Let's
say you've decided to take your involvement in photography up a
notch, going beyond the endless flow of selfies, the keepsakes and
the occasional “doesn't that look cool” grab shot.
Let's
say part of that process was getting a dedicated photo editor
(Photoshop Elements, Paint Shop Pro, Snapseed et al) instead of just
relying on Instragram filters or the effects your smartphone camera
has built in.
Let's
say you're sitting down at your computer, editor open and looking at
a photo and checking out all those cool sliders like “Clarity”,
“Noise Reduction”, “Sharpen” etc.
Let's
say you're wondering what to do with all those nifty, yet daunting
controls, and are hoping to find a tutorial on how to use them to
best effect.
Well,
this ain't that tutorial. Said tutorials are built into the help
functions of the various editors, and can also be easily found on
YouTube or via Google. I can't offer anything that would be better
than any of those, (probably not even as good). What I can do is
offer an important piece of advice that many people starting to use
more advanced editors really need to heed:
Less is
More. Take It Easy. Dial It Back a Notch. Don't Overdo It. Chill.
Yes,
that is all one piece of advice.
You
see, what happens when many people get their hands on some of the
controls in a good editor is they become enamored of what the effect
does, beyond their ability to recognize when the effect has become
destructive to the image. An otherwise nice looking photo can be
ruined by overdoing certain helpful functions, and often a beginner
doesn't recognize what is going wrong. But those with a more
experienced eye will see the problems, and we see a lot of them
because the overuse of certain effects is rampant.
Oh
yeah, here's a second piece of advice:
Keep
Things in Order.
This is
important because certain effects can adversely affect other changes.
For instance, making exposure or contrast changes can make noise
(that grainy look) worse. So noise reduction should be applied before
doing any exposure or contrast changes. Most people use the following
workflow when applying various effects and controls. Note: You should
do any cropping before starting further work on the image.
- Noise Reduction
- Contrast/Exposure/Color Saturation (these 3 are interdependent and often must be tweaked at the same time)
- Special Effects Filters
- Sharpening.
The
reason for this order is simple, and important: each change could
have an adverse effect on the previous changes if done before, rather
than after. I could go into some in depth technical explanation why,
but this isn't really a technical article, so just Google it if you
want.
Now
comes the whole “Chill” part. There are two reasons why changes
should be conservative. The best way to proceed when getting started
is to make a change to a certain point, then dial it back about 10%.
The reason is because of, you guessed it, how future changes will
influence the changes already made.
Noise
Reduction: Digital photography has created an expectation that
images should be as smooth-toned as possible. The days in which
“grain” was an acceptable part of using certain films to produce
photos are gone. In fact, some people assess photos primarily by how
much noise they have, with other factors such as whether the photo is
even worth looking at being secondary. But I digress.
Getting
rid of noise is both easy and a pain. Simple noise reduction usually
involves just clicking a button or, better yet, moving a slider until
the photo looks “clean”. The problem is that reducing noise also
reduces detail, so too much noise reduction can result in a smeared
looking photo, or one that is so artificially digital it looks like
it's CGI instead of a photo of real life.
Sharpening
can recover some of this detail, but not all of it. So it's always
better to take it easy with noise reduction, in part because the next
steps can help reduce noise as well.
Exposure/Contrast/Color
Saturation: One of the great
things about digital is that it's much easier to correct or change
exposure (brightness level) contrast and color saturation. However,
because these three are interdependent in a lot of ways, you will
find that making small adjustments of each on is better than trying
to improve or fix an image by making a big adjustment in a single
area.
Increasing
exposure is going to make most photos look like the contrast and
perhaps color saturation, have been reduced, while decreasing
exposure can have the opposite effect. Increasing or decreasing
contrast can make a photo look over or under exposed, and throw off
color saturation. Increasing or decreasing color saturation can give
an apparent increase or decrease in contrast. This is why adjusting
these three settings really needs a light touch, and some patience,
to get things looking the way you want.
How
does all of this can have an effect on noise levels? Increasing
exposure can make noise more apparent in shadow areas. Increasing
color saturation can make noise more apparent in large areas with
little detail. Contrast changes can make existing noise more obvious.
However, reducing things such as shadow or black level can make noise
less obvious, at the expense of losing some shadow detail. All of
this is why you do noise reduction first, then go gentle with the
next set of changes.
Special
Effects Filters: Yes, they can
make your pics look really cool. When used properly. And sparingly.
As in not on every photo you want to share. Really. Not every pic is
well served by the vignetting, or old style film effects, or overdone
tone mapping. Always keep in mind that as a photographer, what may be
a great shot to you involves your emotional investment in that image,
something that may not be shared by others.
Effects
filters can make a shot look better, or be more attractive to the
viewer, but my advice is the same, to dial the effect back about 10%,
or more, from what you think looks good. Most importantly, always,
always, always consider whether the image is actually improved, or
made more aesthetically appealing, through using effects filters.
Often what people do is take an image that should simply be deleted
and make it worth looking at for a few seconds by adding the
effect(s). However, that doesn't really make the image worth keeping,
it just makes it the photographic equivalent of a gimmick song by a
“One Hit Wonder” musical artist.
Sharpening:
Sharpening isn't really sharpening. No, I mean it. All sharpening
does is increase the brightness or darkness between adjacent pixels,
making lines between light and dark more apparent. Your brain
perceives this as an increase in sharpness, to a point. However, if
you apply too much sharpening, you create halos around certain areas
in the image and it ends up looking like that photo taken with your
brand new $800 dslr kit was made with a cheap cell phone. In fact,
oversharpening is probably the main way in which people ruin images.
Modern
editors have some wonderful sharpening tools. I recommend sticking
with Unsharp Mask to start, although the smart sharpening tools found
in Photoshop and some other apps handle the task quite well. Just
keep in mind that some dialing back of what you think looks good is
usually in order.
Remember
how I said that each change can affect previous changes? This is why
sharpening should be done last, because if you sharpen a photo, then
do something like noise reduction, it won't work as well as it
should. The noise reduction is basically trying to undo the
sharpening process. It's kind of like trying to change your shirt
while still wearing your coat.
Clarity:
This is sort of a “fix a lot
of stuff at once” tool. You should still do noise reduction first,
but clarity can eliminate doing other things like exposure adjustment
or sharpening. As the name of the effect implies, it improves the
clarity of the photo by making all those other adjustments at once.
So the sliders in a clarity control handle the interdependent
adjustments of exposure, contrast, color saturation,
black/white/shadow/highlight levels and even sharpening all at once.
This
sounds like a great tool, and it is for a lot of photos, but it can
also be overused. Too much clarity can result in an image with a
bizarre combination of too much contrast, with grungy looking dark
areas and plastic looking bright areas.
At
this point you might be asking “Can't I just use the 'One Stop
Photo Fix' or similar one-click option in my editor?”
The answer is yes you can. Keep in mind, however, that this control
works by comparing your image to thousands of “normal”
photographs and changing things to match that “look”. That's a
look you may or may not want. Also, photos which are not “average”
will turn out disastrously with one stop options. Concert photos, for
instance, with great areas of darkness and colored lights, will turn
out looking horrible most of the time when fixitall options are used.
The
bottom line is making your photos look awesome using photo editors
takes some time and experimentation. Eventually you will find
settings that make your photos look great, but also like your
photos instead of photos imagined by the programmers of the editor.
That's why I didn't include any examples in this article: how I
produce my photos is based on my tastes and goals, and yours may be
very different. You may like levels of effects that I don't, and
ultimately it's up to you to decide what works best.
One
final consideration, be aware of how others will be viewing your
photos. What looks great on the 5” screen of your iPhone 6 or LG G3
may not look so good on the 22” monitors people are viewing it on
as they peruse Facebook. Problems which you can't see or appear
minimal on a phone or tablet screen become major bugaboos on a
computer monitor. If you're going to be printing photos, that
involves a different approach to editing, and so a different article.
Most
of all, enjoy!
