When Jane Wilkins began as a team
mother for her son’s Northside Youth Organization football team some 40
years ago, she never could have pictured where it would take her.
Now,
after 35 years as the executive director, Wilkins will step down in
May. But not before the organization fetes her with a celebration
following its big parade Saturday.
Wilkins is modest about the
work she’s done to help expand the youth sports program over the years —
the tens of thousands of students who have passed through the program,
the millions of dollars raised. She’s helped lead the NYO from a
football-centric program with a few hundred boys to one that has nearly
5,000 children sign up each year for football, baseball and basketball,
as well as girls’ basketball, softball and cheerleading.

After her divorce, with young children, “I needed a job, they needed a me,” Wilkins said. “It was a nice marriage.”
Leaving the NYO, at 75, is bittersweet, she said. Over the years, the group has become a community of friends.
“It
is my social life. I’m blessed to be a part of these families,” she
said. “I thought I’d put my head on my desk one day and die here. I’m
going to have to close a door and open a window.”
“I get a lump just talking about it, even,” she said.
Former
Atlanta Mayor Maynard Jackson once told her NYO was “the best volunteer
situation in the city, with the exception of the symphony,” she said.
Mark
Croswell, the president of NYO’s board of directors, said Wilkins’ ease
with volunteers is her biggest strength. He described her as magnetic,
and said she had a skill for interacting with people like none he’d seen
before.
“Her ability to bring you in, put you to work without you even knowing it….” he said. “She cares so much for the organization.”
Wilkins
said she’s worked hard to ensure the programs offer something for
everyone. For her, it’s been a utopia, even as there have been
challenges like a drop in participation in the football program as
parents grow concerned about the effect of concussions. She has worked hard to ensure players are taught proper blocking and tackling so that children can continue to play, safely.
Her
only regret, Wilkins said, is that with the exception of one grandson
who played basketball for a year, her own grandchildren did not
participate in the NYO programs.
“Would you believe I have four
granddaughters, all of whom are soccer players, and we don’t have it?”
she said. “It would have been nice.”
The
Northside Youth Organization will celebrate the career of retiring
executive director Jane Wilkins at the Opening Day ceremonies for
baseball and softball on Saturday. The ceremony will be held around noon
in a tent in the parking lot at 140 West Wieuca Road Northwest in
Atlanta. Anyone who has been involved with NYO is welcome to attend.
HTHC Notes: NYO is one of my very dear clients. I will miss working with Jane.

Technology used to move forward like a freight train (literally at
one point), but now it's more like a 300 mph bullet train. You just have
to blink and you'll miss the latest smartphone, processor upgrade, new
type of connector or any dozens of other developments that never seem to
stop.
With technology arriving this quickly, information about
how to use it correctly can come and go just as fast. Yesterday's
standard operating procedure is tomorrow's mistake. And what used to be
good advice for avoiding danger might not be relevant anymore.
Today,
we're going to tackle seven persistent tech myths that started out
good, but that you really shouldn't believe anymore. These cover the
range from battery charging to data disposal to privacy and general tech
buying. How many of these did you already know?
1. You shouldn't charge your gadget overnight
Many
people are afraid to charge their phone or tablet overnight because
they think it might overcharge and destroy the battery. I also field
this question from people worried about leaving laptops plugged in 24/7.
There
is a difference between knockoff chargers and third-party chargers. A
third-party charger is an Apple- or Android-compatible charger from a
reputable company like Belkin or Monoprice.
Third-party chargers are OK
to buy. Just know that, in general, they won't charge your gadget as
quickly or reliably as a maker’s official charger.
Knockoff
chargers usually don't have a brand name, or they say they're from
Apple, Samsung, HTC, etc., but have a ridiculously low price. Knockoffs
are often responsible for the horror stories you hear about gadgets
bursting into flames or electrocuting users. Avoid them at all costs.
3. You have to let your battery drain to zero before charging
Nickel-Cadmium
batteries, which used to be a staple of home electronics, had a "memory
effect." That meant if you didn't drain them fully before each
charging, they'd eventually stop holding as much electricity.
The
Lithium-ion batteries that have replaced them in modern gadgets don't
have that problem. In fact, Li-ion batteries last longest when you keep
them between 40% and 80% charged. Also, if you let Li-ion batteries
discharge completely for too long, they can be permanently damaged or
become dangerous as we explain here.
But
Li-ions do have one challenge. The batteries have a built-in sensor
that tells your gadget how much electricity is left in the battery. Over
time, that stops matching up with the battery's actual charge. To reset
it, you have to charge the Li-ion battery to full, let it run down to
the point where your gadget gives you a serious battery warning and then
charge it back up to full again. However, this only needs to be done
every three months or so.
For some gadgets, you might not need to
do it at all. Apple used to recommend this process but now says it is no
longer needed. Check your gadget's manual to see if it has any specific
directions.
4. Always shut down your computer at night
This
myth goes all the way back to the early days of computers. Back then,
computer parts, especially hard drives, wore out much faster than they
do today. So, the idea was that to make your computer last longer, you
should always shut it down at night. Some people still cling to that
concept, and there is a little grain of truth in it.
However,
modern computers have more-robust parts, which means you can let them
run with little to no problem. Whether you shut down your computer
nightly now just comes down to personal preference. If you want your
computer to do things like back up, update or other intensive tasks, you
can schedule them at night while you are not using your system.
If you're concerned about saving energy, turn it off. Or you can use one of your computer's many power-saving modes, which are faster for getting it going again in the morning.
5. You need to defragment your hard drive
This
is a myth that used to be true, but no longer is. Given the way
conventional magnetic hard drives read and write data, over time bits of
data that should be next to each other get jumbled. So, to pull up a
file, the drive would have to travel to 15 different places instead of 1
or 2, which slows down your system.
It used to be that you'd
occasionally need to manually run a utility to defrag your system. Now,
that function is built into Windows and other major operating systems,
and it's run it automatically as needed. There's no need for you to do a
thing.
In fact, defragmenting can even cause a problem if you're using a solid-state hard drive.
Not only do SSDs not have fragmentation problems, the memory cells are
only good for a certain number of reads and writes. Running a
defragmenting program just wears out your drive faster.
6. You can completely wipe data
Hopefully,
you know that when you delete a file from your computer it isn't gone
for good. It's still hanging around on your hard drive waiting for
another file to overwrite it. Until that happens, you can recover it.
That's
a problem if you're selling or giving away a computer; you never know
what information a computer-savvy person can pull from the system. You
need to make sure the data is gone for good, but how?
In the olden
days of magnetic media with early hard drives and floppy disks, waving a
magnet over the drive or disk would do the job. However, modern hard
drives are much more resistant to magnetism, so that won't work.
That's
fine for conventional drives, but because of the way solid-state drives
work, both in computers and mobile gadgets, you can never be sure
you've gotten everything. Mobile gadgets do include a reset feature, and
many SSDs come with their own wiping software. However, something might
get missed.
In most cases, no one is going to go looking for
what's been left behind, or get anything too important. However, if
you're really worried, you can keep your gadgets at home and use them for other projects.
You can also remove your hard drive from the computer before giving it
away and store it, turn it into an external drive, destroy it, or make art with it.
Interesting
fact: Since 2007, the federal government mandates that for hard drives
and other media that have contained classified material, the only option
is to completely wipe and then destroy them.
7. Private browsing is totally private
Every
Web browser has a private mode. When private browsing mode is on, the
browser won't record where you go and it wipes most of the information
someone using the computer could use to piece together your online
travels.
What
you might not know is that private browsing isn’t foolproof. It doesn't
hide your browsing from your Internet service provider, the sites you
visit or any law enforcement that happens to be watching. Ditto if
there’s a logger on the computer or the router is set to record sites
visited. Like most things in tech, private only means that it’s harder
to find.
Bonus: More is always better
This is a general
myth that tech manufacturers love because it boosts sales. However, it
isn't always true, and sometimes more can even hurt you.
You might
be deciding between a laptop with a 256 gigabyte solid-state hard drive
and a 1 terabyte conventional hard drive. A 1TB drive is four times
larger, but an SSD is much faster and more reliable. Plus, most people
rarely even fill up a 256GB hard drive.
Similarly, you shouldn't
automatically buy the camera with more megapixels or the smartphone with
the highest-resolution screen. In a camera, image quality is as much
about the size of the image sensor as the number of megapixels.
With
smartphone screens, after a certain point you can't tell the difference
in resolution (and most high-end and mid-range smartphones are past
that point). However, a higher-resolution screen burns battery life
faster.

If
your device is broken, never fear. At the very least Apple will recycle
it for you in any of their stores, leaving you with an easy way to
avoid putting your device in the garbage and letting it become e-waste.
There are other sites online where you can get a little cash for them,
too, but only a little. So it’s up to you whether you want to try to get
rid of it by Apple recycling or by an online store. Either way, please
don’t just throw it away.

Apple’s
new iPhone SE hits the market next week. With a starting price of $399
unlocked, it’s going to be one heck of a deal, especially if you’ve been
looking for a new smartphone that actually fits in your hand.
Of
course, if you do want something larger, there’s the equally powerful,
though more expensive, iPhone 6s. And if you’re looking for a really big-screen handset, you can opt for the iPhone 6s Plus.
Updated to reflect that the iPhone SE has a 1.2-megapixel front camera.
Which
leaves the iPhone 6 and 6 Plus. Apple’s oldest smartphones were already
looking a little long in the tooth, thanks to the 6s and 6s Plus. And
now with the SE, they look positively ancient.
In fact, at this point you’re probably better off avoiding the 6 and 6 Plus altogether. Here’s why.
They’ll get slower faster
OK,
so the iPhone 6 and 6 Plus are old, but they’re basically the same as
the 6s and 6s Plus, right? Actually, they aren’t. While the 6 and 6 Plus
look exactly like those newer offerings on the outside, they’re far
different on the inside.
The
6 and 6 Plus come with Apple’s A8 processor and M8 coprocessor; the 6s
and 6s Plus come with the company’s A9 processor and M9 coprocessor.
That might not seem like a big deal right now.
But
if you’re buying a new phone and you’re going to stick with it for two
years or more, buying one with outdated innards like the iPhone 6 or 6
Plus means that, by the time you’re ready for a new phone, your current
one will likely be slowing to a crawl.
Sure,
the 6s and 6s Plus will eventually become slow and outdated, too. But
two years from now they’ll be running far better than the 6 or 6 Plus.
Camera envy
The
iPhone 6s, 6s Plus, and SE all come with the same 12-megapixel iSight
camera. The iPhone 6 and 6 Plus, on the other hand, still use Apple’s
older eight-megapixel camera. Naturally, photos should look a bit
crisper when taken with the 6s, 6s Plus, or SE than those shot with the 6
or 6 Plus.
The
iPhone 6s, 6s Plus, come with improved 5-megapixel Face Time cameras.
The 6 and 6 Plus come with Apple’s older 1.2-megapixel Face Time
cameras.
If
you’re the kind of person who loves taking selfies, then the 6s and 6s
Plus are far better choices than the 6 and 6 Plus. Not only will images
look sharper and offer more detail.
The
iPhone SE, as well as the 6s and 6s Plus also also have Apple’s new
Retina flash, which uses the display as a flash to light up shots taken
in low-light settings.
Display differences
Apple’s
iPhone 6 and 6 Plus, like the 6s and 6s Plus, come with 4.7-inch and
5.5-inch displays, respectively. The only difference between all those
screens is that those on the 6s and 6s Plus support Apple’s 3D Touch
technology, which lets you press harder on the phones’ displays to
access secondary app menus.
Sure,
images and videos will look exactly the same on the 6 and 6s and 6 Plus
and 6s Plus. But 3D Touch is a genuinely helpful feature that more and
more app makers will likely take advantage of in the coming years. If
you buy a 6 or 6 Plus, you’ll lose out on those advantages.
On
the flip side of things, if you were thinking about upgrading to the
iPhone 6 from your iPhone 5s because you wanted a faster phone but not
necessarily a larger screen, you’ve now got the iPhone SE. So you can
get your faster phone without having to upsize.
The price is … wrong
Price
is the real reason the iPhone 6 and 6 Plus are now pointless. With the
introduction of the $400 iPhone SE, consumers now have a high-powered,
low-cost iPhone.
If
you want a bigger screen on your handset, you’ve got the $650 iPhone
6s. And if you want the biggest possible screen, you can opt for the
$750 iPhone 6s Plus.
The
iPhone 6, meanwhile, costs $550, while the 6 Plus costs $650. Yes,
they’re still $100 less expensive than the 6s and 6s Plus, but you’re
getting a lot of added functionality and longevity for that extra cost.
If you really want to save some cash, you’re way better off buying the
relatively inexpensive iPhone SE, with its improved performance and
camera.
In other words: There really doesn’t seem to be any good reason to choose the 6 or 6 Plus over one of Apple’s other phones.

On March 31, you’ll be able to buy the newest member of the iPhone family: the iPhone SE.
What
does SE stand for? Apple says Special Edition, but you could also sum
it up this way: Same Engine, Smaller Exterior. Because Apple has crammed
the chips, guts, and camera of the iPhone 6s into the crisp-cornered
body of the tiny iPhone 5s.
On
one hand, Apple now seems to be following the Samsung model of spewing
out phones and tablets in every conceivable size, rather than innovating
in more substantial ways.
On the other hand, Apple is correct that a certain chunk of the population doesn’t like the jumbo-ification of smartphones, such as the big iPhone 6s and even bigger 6s Plus.
Some people, small of hands, still cling to the three-year-old iPhone
5s (with its 4-inch screen) despite the gigantic improvements in speed,
camera power, and wireless abilities in the newer phones.
Three
things about the SE are newsworthy: First, the battery life is about 30
percent better than the iPhone 6s’s (good for 13 hours of Web browsing,
Apple says) — a side effect of having a screen the same size as the 5s.
Second,
at $400 without a contract (for the 16GB model), the iPhone SE is the
least expensive iPhone that Apple has ever offered. Finally, with its
4-inch screen, the SE is now the smallest brand-name smartphone sold in
America.
The
SE is loaded with features (Apple Pay, Live Photos, fingerprint
unlocking, 4K video recording, hands-free “Hey Siri” voice commands, and
more), but not a single one of them is new in the SE.
It actually lacks
one modern feature of the iPhone 6s: It doesn’t have 3D Touch, which
makes shortcut menus pop up when you apply additional pressure to the
iPhone 6s’s screen. (Compared with the 6s, the SE screen isn’t quite as
colorful, the front camera not quite as good, and the fingerprint reader
isn’t quite as fast, either.)
In
other words, a review of the iPhone SE would, for all intents and
purposes, be a re-review of the iPhone 6s. Therefore, to save us both
time and effort, here’s what I said about the 6s, in lightly updated
form. After all: If Apple can recycle its finest ideas, why can’t I?
(You can skip to the final paragraph for my final thoughts on the new
phone.)
Things you’ll appreciate all day long
The biggest new thing is speed.
The
processor inside: Apple says it’s “up to 70 percent” faster than the
iPhone 6. Opening apps, switching apps, processing things — it all
happens faster.
Apple
also says that it has tuned both its Wi-Fi and its cellular (LTE)
antennas to make them faster. This, too, is screamingly obvious when you
call up websites side-by-side on the old and new phones. Who doesn’t
like faster Internet?
Things you’ll appreciate occasionally
Apple
makes much of the iPhone’s new camera. It takes 12-megapixel photos, up
from 8. And it can capture 4K video (that is, four times the resolution
of high definition).
But
as Apple itself has pointed out many times, having more megapixels does
not mean you take better photos. More megapixels can be useful when you
want to crop a wide photo down to a smaller subject and still have
enough resolution for a print. Otherwise, more megapixels just means
bigger files — and your phone will fill up faster.
I’ve
been taking lots of pictures in lots of lighting situations with the
old and new cameras side by side, and I can’t tell any difference. Can
you?
(Hint: The iPhone SE photos are on the right.)
Now,
it’s not a slam to say that photos taken with the SE don’t look any
better than those captured on an iPhone 6 or 5s; the iPhone’s camera was
already among the best ever put into a phone. But you shouldn’t expect a
leap forward in most of your shots.
As
for the 4K video: Once again, not much to write home about. First,
because more pixels in a video doesn’t mean it’s a better video; the
only guarantee is that it eats up more storage on your phone.
(Fortunately, you can turn off 4K recording in Settings.)
Second,
because you probably don’t have anywhere to play the 4K video you’ve
captured with this phone! Paradoxically, iPhone itself doesn’t have
enough pixels to play 4K video. And don’t think you can wirelessly beam
them to your television using an Apple TV; even the new Apple TV can’t handle 4K programming.
(You can post your 4K video to YouTube, although very few people can play them back in 4K.)
But there is one camera enhancement that’s pretty awesome: the selfie-screen flash.
The
new iPhone offers a “flash” for taking selfies. At the moment you take
the shot, the screen lights up to illuminate your face. Better yet: It
samples the ambient room light and adjusts the color of the screen’s
“flash” to give your face the best flesh tones.
This
trick — flashing the screen — is inherited from the Photo Booth app on
the Mac. It’s been flashing MacBook screens white to light up your face
for years.
Of
course, the iPhone screen is too tiny to supply much light, even at
full brightness. So Apple developed a custom chip with a single purpose:
to overclock the screen. In selfie situations, the screen blasts at
three times its usual full brightness, just for a fraction of a second.
It is crazy bright.
(It’d
be cool if you could turn that on manually — to improvise illumination
for an emergency plane landing, for example. But you’d burn out your
screen and eat up your battery charge.)
Anyway,
it works fantastically well. Compared with phones with no front-facing
flash, or compared with other phones’ noncolor-corrected flashes, the
iPhone 6s’s front-facing screen flash is clever and effective. Every
time you take a flash selfie, the results are as clear-cut and dramatic
as this comparison:
And one thing that’ll make you scratch your head
The
other much-touted feature is something called Live Photos: still photos
that play back as three seconds of video, with sound.
What
you’re getting is 1.5 seconds before the moment you snapped the photo,
plus 1.5 seconds after. (During this 3-second capture period, a LIVE indicator
glows on your screen.) In the phone’s Camera app, there’s a special
icon at the top; that’s the on/off switch for Live Photo capturing. (The
factory setting is On.)
Your
obvious concern might be: “Whoa, Nellie! 12-megapixel photos? At 30
frames a second, that’s 90 frames, each 12 megapixels — 90 times as much
storage as a still image!”
Well,
no. The actual photo you snapped is a full 12-megapixel shot. But the
other frames of the Live Photo animation are only screen resolution —
not even one megapixel per frame. Overall, Apple says, an entire Live
Photo (still, video, sound) takes up about twice as much space as a
still photo.
(The
downside of that clever compression scheme: You can’t extract a
full-resolution still image from one of the video frames. That’d be
cool.)
Behind the scenes, a Live Photo has two elements: a 12-megapixel JPEG still image and a 3-second QuickTime movie.
When
you try to share a Live Photo, a special icon reminds you that you’re
sending a larger-than-usual file. You can tap to turn it off (and
therefore send only the JPEG):
If
you decide to proceed with the Live Photo turned on, what happens next?
Depends on what kind of device receives it. If it’s running the latest
Apple software (iOS 9 or OS X El Capitan), the Live Photo video plays on
that gadget, too. Facebook accommodates Live Photo playback, too.
If
it’s a device or software program that doesn’t know about Live Photos —
you send it as a text message, for example, or open it in Photoshop —
only the JPEG image arrives at the other end.
This
whole three-second video business isn’t new. HTC’s version, back in
2013, was called Zoe; Nokia’s, last year, was called Living Images.
Pocket cameras like the Nikon 1 have a dedicated button just for
capturing them.
Maybe
Apple was inspired by the popularity of animated GIFs, or 6-second Vine
videos, or 15-second Instagram clips. I’m not exactly sure what you’d
use Live Photos for, or how they’re an improvement over a video clip
you’ve shortened yourself — but then again, I’m not one of those crazy
snake people.
A new era of pricing
You
can get the iPhone SE for “free” with a two-year contract from Verizon
or Sprint. It’s available in four colors of metal back: silver, gray,
gold, and rose gold.
“Free,” of course, is a subsidized price; you’re paying off the phone’s actual price over the two years.
Nowadays,
more people prefer to buy the phone outright and pay monthly only for
cell service. For that, it’s $400 for the iPhone SE; add $100 to get
four times the storage (64 GB). You should definitely do that; 16
gigs won’t get you far. (And why doesn’t Apple offer the most logical,
in-beween capacity, 32 gigabytes? Insert your own evil conspiracy theory
here.)
But
there’s a third way to do it: Rent the phone. Each cell carrier — and
now, Apple itself — is prepared to lease you your phone. You pay nothing
up front, and then you pay a monthly equipment fee of around $16.50 a
month. (That’s T-Mobile’s and AT&T’s price for a two-year rental.
The other carriers haven’t yet announced their pricing.)
What SE really stands for
The
$400 for this Smartphone Extraordinaire is a Smart Expenditure. On one
hand, it still has the Sharp Edges of the iPhone 5s, and its addition to
the lineup will remind critics of Samsung’s Excess. On the other hand,
its 1.5-day battery life means that it only Sips Energy. This is a piece
of very Solid Equipment, even if it is a Special Edition for people
with Small Extremities.

With
every update to a new operating system comes a few kinks and bugs.
However, iOS 9.3 seems to be causing a lot of problems for some
users. Last week, some people who updated their devices to iOS 9.3 had trouble getting into their phone. This week, devices seem to be crashing when you try to open links in apps like Safari, Notes, and Chrome.
We’ve
put together the common problems that keep cropping up in iOS 9.3 in
this post, as well as common iOS 9 problems and how to solve them (read the iOS 9 troubleshooting guide here).
Crashing links
Hundreds of users have posted
in an Apple Support thread that they are able to open links in various
apps. The app will even freeze afterward. For some, nothing happens when
they click a link, and for others, tapping and holding links causes the
device to crash.
@AppleSupport I have a problem with opening links in Safari in iOS 9.3 iPhone 6S.
Many
of the people who are reporting the bug seem to be having issues on the
iPhone 6, 6S, and 6S Plus, but there are some people having the same
problem on earlier devices and some iPad models. The bug isn’t solely
restricted to iOS 9.3, either, as some people on 9.2.1 and other
versions are having similar issues.
Some users are saying that turning off Javascript in Safari fixes the problem in the browser. However, the bug still persists with other apps like Mail and third-party apps.
9to5Mac reports
that the problem may be caused by installing third-party apps, as the
issue only appeared after a third-party app was installed on an
unaffected iPhone 6 and iPad Pro and the problem lingered after the app
was uninstalled.
@AppleSupport received
a lot of tweets from frustrated people citing the same issue and is
asking those who’ve been affected to direct message the support team, so
it can better assist them.
According
to some users in the support thread, the Cupertino company is aware of
the issue and is working on an update within the next two days. We have
reached out to Apple and will confirm if this is true.
Activation issue
Apple
has already released a fix for the activation issue in a new version of
iOS 9.3, build 13E237, which you can download over the air or via
iTunes. We’ve also put in a work around for people who are still having
trouble or have yet to download the update.
The
bug affects iPhone 5S devices and earlier, as well as iPad Air devices
and earlier. Your iOS device will essentially ask for a password to
authorize your account and complete the update process. For some people,
they couldn’t get their devices to activate, and the message,
“activation server is temporarily unavailable” appeared onscreen.
Apple
addressed the issue in a support page on its website, offering steps
for users to get around the problem, as well as a firmware update. The
build number initially changed from 13E233 to 135236, and now it’s on
13E237. It should solve the problem and allow easy upgrading for those
with older devices.
If
you’re having trouble, try signing into iCloud and confirm that your
device is listed in the My Devices section. If that doesn’t work, try
connecting your device to a computer and open iTunes. If you have the
latest version of iTunes, select your device and there should be an
Activate button near your device name. You then just need to enter your
Apple ID and password.
We’ll update this post as we hear about more iOS 9.3 bugs and fixes for them.

Capturing a great photo is like capturing lightning in a bottle. You
don't get a second chance at it so you better get it right the first
time.
At least that's the way it used to be. Thanks to digital
photo editors, you can fix little mistakes and turn ho-hum pictures into
fantastic photos.
The
programs listed here range from user-friendly to advanced. They're all
free, so you can find the right one for you. Here we go: Paint.net
was originally created as a free replacement for Microsoft's Paint.
Like Paint, Paint.net is really easy to use, and it's extremely useful.
It
lets you add text, paint, patterns, shapes and gradients to any
photograph. It also includes tons of features that let you sharpen, blur
or remove grain and noise. But the best part about Paint.net is that if
you mess up, you can revert back to your original photo.
GIMP
was designed as a free alternative to Photoshop. In case you don't
know, Photoshop is a powerful and expensive photo-editing tool that's
widely used by professional photographers.
GIMP can do almost
anything Photoshop can do, including adding layers, filters, and more.
It can save files in Photoshop's PSD format. Plus, it's open-source
software, which means it's being updated and improved all the time.
RawTherapee
is a free, full-featured RAW editor that lets you do the same things as
pricey programs such as Adobe Lightroom. You should double check to
make sure that your camera's file formats are supported by RawTherapee
and that you download the correct version of the software.
If you
have a DSLR camera, you may be taking photos in a RAW file format. These
are sometimes called "digital negatives" because they contain the
unprocessed data from the image sensor of a camera.
These files
have more detail and a wider dynamic range. You can also edit white
balance and exposure after you've taken a photo. But you'll need special
software to view them and to edit them.
Luminance HDR
was designed to create high dynamic range photos from multiple photos
of one image taken at different exposures. You'll be able to tone map
(adjust colors), rotate, resize and much more.
Film captures a
wider range of luminance than most digital devices. You can achieve that
same look for digital photos using HDR imaging found on some cameras,
or photo-editing software like Luminance HDR.
Fotor
is a free download for PCs, Macs and smartphones that can turn basic
snapshots into colorful masterpieces. It just takes a few clicks and
there's hardly any learning curve. You can add effects to any photo,
create brilliant collages or customize photo cards for the holidays.

There was a great Huffington Post post
a couple years ago: a Radio Shack ad from 1991, accompanied by the
comment that every single product in it has now been replaced by the
smartphone. You know: camera, radio, clock, calculator, camcorder, and
so on.
One particular 1991-era appliance wasn’t in that Radio Shack ad, but should have been: a scanner.
Turns
out your iPhone or Android phone is fantastic for “scanning” contracts,
articles, book pages, receipts, sheet music, driving directions,
recipes, and anything else on paper. All you need is the right free app.
Now, do me a favor: Don’t reply, “Why would I need a scanning app? I can just take a photo with my phone!”
It’s really not the same thing.
A
good scanning app can recognize when a page is framed properly and snap
the shot automatically. It can straighten, rotate, and un-warp the
image to produce a tidy, perfectly rectangular page. It plays with the
color, brightness, and contrast to eliminate shading and shadows,
leaving you with a PDF that you can email or upload to Dropbox, Google
Drive, iCloud Drive, or another storage service.
Some of these apps can even perform OCR (optical character recognition) on the scan — meaning they can convert a picture of text into actual
text, which you can then edit, copy, or paste into another app. This is
fantastically useful if you’re a student, researcher, lawyer, or any
other kind of literate person.
It’s
hard to express how happy people are with their scanning apps; I mean,
they rave about them. Look at these reviews on the iTunes app store:
What to look for
I’ve just spent several days testing no fewer than 18 of these scanning apps. (Correct: I have no life.) In the course of that testing, I came up with a master list of 14
features that I think those apps should have — and I discovered that
it’s very hard to find one app that offers all of them. Ready?
Free.
Automatically finds the borders of the page.
Automatically straightens, rotates, and de-skews the page.
Lets you readjust the cropping later.
Lets you specify the page size for the result (letter, legal, A4, etc.).
Rapid-fire batch mode (snap one page after another without pausing to process each one).
Password-protects documents.
Generates multipage PDFs.
Provides brightness/contrast adjustments.
Supports annotation (draw on or sign a document).
Exports to all the usual places (Dropbox, Box, Google Drive, iCloud Drive, etc.).
Faxes directly from the app.
Automatically saves each scan to a chosen location (Dropbox, Google Drive, etc.).
Converts the picture to actual typed text (OCR).
Life
is short, so I’ll spare you the blow-by-blow of my incredibly boring
journey through Genius Scan, Genius Scan+, Google Drive, Scanner Mini,
Scanner Pro, iScanner, iScanner Pro, Scannable, DocScan, DocScan Pro,
TurboScan, CamScanner, CamScanner Premium, iScanner, ScanBot, ScanBot
Pro, JotNot Pro, and Fast Scanner.
Instead, I’ll just share with you my findings:
There are lots of terrific scanning apps.
Many come in both free and paid versions. Sometimes the differences are
minor: For example, you can email scans from any of them, but often
only the pro (paid) versions let you save your scans to Dropbox, Google
Drive, and so on.
The more features it has, the more complicated it becomes. Just try figuring out how to add pages to a scan you made yesterday, for example.
Step count matters.
Some of these apps do a lot, but you have to tap your way through them —
and there are lots and lots of taps. And each of those taps is another
decision point for you, another pause, another moment of having to
think. Automated is better.
Compare
here, for example, the manual, tap-when-you’re-ready apps (like Genius
Scan) to the ones that automate the procedure (like Evernote Scannable):
That said, for the sake of simplicity, here are the apps that offer the best combination of simplicity and automation:
Best free app (iPhone, Android): ScanBot
This app can do finger-free scanning: Just aim and wait as ScanBot auto-detects, auto-straightens, and auto-snaps each page.
Further
distinguishing this app is the fact that you can set up one-tap
“workflows” such as Send by Email or Save to Dropbox. In fact, you can
specify an auto-upload folder on those services (Dropbox, iCloud Drive, Google Drive, Evernote, OneDrive, OneNote, Box, WebDAV, FTP, and others.)
You
can use the LED light on your phone to illuminate your page; there’s
built-in Help; you can specify file size and resolution, and there are
one-tap buttons for naming your scans (after the time and date, your
location, and so on).
You can upgrade to two levels of Pro, each of which adds even more Holy Grail.
For
$6, you get impressive OCR; annotations; a truly superb signing feature
(for contracts); automatic file naming, and Quick Actions (tap a phone
number in the scanned text to dial it, a URL to open that Web page, or
an address to see it in your Maps app).
For
$8, you get all that, plus auto-upload; the option to password-protect
the app (or, on the iPhone, protect it with your TouchID fingerprint);
and automatic smart file naming.
Two peculiarities to note: First, on the iTunes app store, if you search for the name ScanBot, the name of the app that comes up is different:
But yes, that’s the app you want.
Second, you won’t find Pro versions listed in the app stores. Just get the free one, and then use in-app purchases to upgrade.
ScanBot
has more “Please Wait” messages between steps than some rivals, and it
lacks the rapid-fire, uninterrupted batch shooting of CamScanner
(described below). But overall, this is the smartest, most complete free
scanning app you can install.
Most polished app (iPhone): Evernote Scannable
This
is a beautiful, fast, idiot-proof scanning app. You point the phone at
page after page — without ever touching the screen — and marvel as it
auto-recognizes the page, snaps it, straightens and parses it, all by
itself. You don’t have to tap at all until all your pages have been
snapped. And even then, all you do is tap a little checkmark to finish.
Easy
to use? That’s for sure. There are only two screens in this app: The
one where you snap things, and the one where you look at the resulting
documents:
Scannable
gives you the option of turning on your phone’s LED for better
lighting, or making your phone vibrate for scan confirmation.
You
can send your scans to any app listed on the standard iOS Share sheet:
Send by Mail, Messages, Notes, Dropbox, or iCloud Drive.
And, as you’d expect, every scan can be auto-saved to Evernote, the powerful free note-keeping app.
There
is, however, one very weird limitation with this app: It auto-deletes
every scan after 30 days. Because Scannable was designed to be a hungry,
hungry hippo for feeding Evernote, that shouldn’t matter; everything
you scan can be safely stashed the moment you take it — in Evernote.
But
if you’re not an Evernote person, the 30-day thing means that you
should export or email each scan while you’re thinking about it.
The most features (iOS, Android): CamScanner
If
I were a spy, having to snap multiple pages of the enemy’s secret
nuclear plans with only 30 seconds in their vault, this is the app I’d
want. Its batch mode lets you snap page after page with no intermediate
screens, no pause to save, and no “processing” cursor. It’s great at
scanning lots of pages fast.
It doesn’t snap the pages automatically, though — you have to tap the shutter button for each capture.
Otherwise,
though, this is an elaborate system, full of features that no other app
offers. You can invite colleagues to comment on your scans, sync your
scans across devices, send people a link to download your scan, add
notes to a scan. There’s a full-blown drawing tool, so that you can sign
or annotate a screen.
Incredibly,
there’s even OCR. CamScanner can analyze the scan and turn it into
typed text. In the free version, alas, all that gets you is the ability
to search your scans for a certain phrase. To export or edit the OCR’d
text, you have to upgrade to the Premium version.
Distressingly, that Premium is a subscription: $5 a month, or $50 a year. (Rival apps, like Scanner Pro, have a one-time cost
of just $4.) In addition to the OCR export feature, CamScanner Premium
gets you 10 GB of online storage, the option to auto-upload every scan
to Box, Google Drive, Dropbox, Evernote, or OneDrive, and more.
The
heartbreaker is that the free version stamps “Scanned by CamScanner” at
the bottom of every page. If it weren’t for that, CamScanner would
easily be the best free cross-platform scanning app.
Honorable mention (iPhone, Android): Scanner Mini, Scanner Pro
Here’s
another free app that stands out for its fully automatic snapping. It’s
super cool to watch the app find the page you’re scanning and then
auto-frame it:
The app is also easy to figure out, gives you the option of using flash, and the scan quality is great.
Unfortunately,
the free version offers only two export options: send the resulting PDF
or JPEG by email, or save it to your camera roll.
If
you’re willing to pay $4 (ooh! scary!), though, you can upgrade to the
new Scanner Pro 7, which gets you the whole enchilada: the ability to
upload to Evernote, Box, OneDrive, Google Drive, or Dropbox, and very
good OCR.
Free OCR through Google Drive (iPhone, Android)
If
you use the Google Drive app on your phone, you already have a scanning
app — with OCR! But you’ll never find it without some directions, so
here we go:
In the app, tap the round red + button, then tap Scan. (On the iPhone, there’s no Scan button; try tapping Use Camera, which works almost as well.)
The scanning process is very basic: nothing is automated, and you can’t adjust the crop or perspective of the result.
But
here’s the great part: Everything you scan automatically and instantly
appears on your Google Drive, your free 15 GB “hard drive in the sky.”
And here’s the really
great part: Once you’re looking at your Google Drive list, you can
right-click the scanned document, choose Open with -> Google Docs —
and read the interpreted, OCR’d text!
The
words OCR never appear anywhere (probably because most people don’t
know what that is). But yeah, that’s all you have to do: Open with ->
Google Docs.
Now
that you know about this trick, you know that you can, in effect, add
OCR to any scanning app. Just direct the result to Google Drive, and
boom: You can use Google’s online OCR feature for free.
Microsoft Office Lens
Here’s
the world’s simplest scanning app — a perfect solution for the easily
overwhelmed. It’s free and it’s available for iPhone, Android, and (of
course) Windows Phone.
The app automatically finds and frames the page, with excellent precision and very cool animation. You tap the Snap button, then you tap Done.
You can then send the scanned page to OneNote, or convert it to a Word
or PowerPoint file. (If you scan a business card, there’s some basic OCR
that extracts the contact info into a VCF file — which you can, with
some effort, add to your contact list.)
But
there’s no way to capture a multipage document, and there are no
security features, no option to edit borders manually, no brightness or
contrast adjustments, no annotation or signature features, and no
additional export options.
Scan these options
If you’ve never tried a scanning app, you’re in for a real treat.
For
occasional use only, grab Evernote Scannable (iPhone only); it’s so
simple and fast, it doesn’t matter if you only use it once every couple
of months.
Otherwise,
check out either Scanner Mini or Cam Scanner, both free and available
for iPhone or Android. You’re already carrying a camera, radio, alarm
clock, calculator, and camcorder in your pocket; surely there’s room in
there for a scanner.
