We all strive to produce photos that are perfect right out of the camera. Unfortunately,
sometimes what comes out of the camera doesn't quite match what we envisioned
when we pressed the shutter button. Here are some easy things you can do to
improve your photos after the fact.
STEP 1: Crop The Image
It's best to get the framing right in camera, but often we don't.
So examine your photo and check that it is properly aligned (i.e., the horizon
is horizontal) and framed. If not, use the image-editing software's Rotate
feature to align it, then crop as necessary. It's best to crop the image
before doing the following steps, because it will give you a smaller image file
to work with, and that will require less computer resources so things will go
faster.

Here's
an original image that's too dark, the subject is too far
to the left, and there's clutter in the background. Cropping
the image solves the too-far-left problem and eliminates most
of the clutter.

STEP 2: Level The Field
It's tough to judge color rendition when the image is too dark or too
light, so adjust image brightness and contrast carefully. The image-editing
program's Brightness/Contrast control is seldom the best way to do it.
The Levels control provides you with much more control. Go to Image>Adjust>Levels,
and you'll get a window similar to the one shown (I use Photoshop, but
other image-editing programs have similar capabilities).
The Levels window displays a histogram--a graph of the tones in the image.
With Photoshop, dark tones are on the left, light ones on the right (some image-editing
programs may reverse that). Below the histogram are three arrows. Moving the
left one to the left edge of the histogram will make the darkest tone in the
image pure black. Moving the right arrow to the right edge of the histogram
will make the lightest tone in the image pure white. (You won't always
want pure black and pure white--go by what looks right to you on the screen.)
Move the middle arrow to adjust the mid tones--moving it left makes them
lighter, moving it right makes them darker.
Levels adjusts the entire image. If specific portions of the image are too light
or too dark, use the Dodge and Burn tools. The Dodge tool makes the area to
which it is applied lighter, the Burn tool makes the area darker. Working on
a Duplicate Layer rather than an Adjustment Layer will keep the dodging and
burning separate from previously corrections.

To
solve the too-dark problem, use Levels: Moving the right arrow
to the left restores a true white to the lightest tone in the
image, and moving the middle arrow to the left lightens the middle
tones.

STEP 3: Color Adjustments
Once the image looks good tone-wise, adjust the colors if necessary. The easiest
way to do this is via the Color Balance sliders. Go to Image>Adjust>Color
Balance, and adjust the red/cyan, green/magenta and blue/yellow sliders until
the colors look right. If the image has a neutral tone, you can often adjust
the color balance by clicking the middle eyedropper in the Levels window, then
clicking on the neutral area to neutralize the clicked area.
When the colors look right, go to Image>Adjust>Hue/Saturation, and adjust
the saturation slider for optimal effect. With Photoshop, moving the slider
left reduces saturation, moving it right increases saturation.

This
shot was made in early-morning light, which gave it a yellow cast.
Some might like that; if not, adding some blue with the Yellow/Blue
Color Balance slider removes the cast.
