Adjustments
There are far more postproduction adjustment when shooting—should only need a little tweaking,
options than can be covered in this book. However, using just a few adjustment tools. The most useful of
most photos—as long as you made the right choices these are shown below.
ADJUSTMENT BEFORE AFTER
ROTATE AND CROP
There are two reasons to crop a photo: to remove unwanted details
around the edges, or to change the aspect ratio so that you can improve
the composition. You can rotate a photo dramatically to change its
orientation, or apply it more subtly to straighten out key elements.
EXPOSURE
The Exposure adjustment enables you to correct any errors in exposure
and to adjust the photo’s brightness to your taste. You can also use it to
create a high- or low-key photo (see p.72). Lightening a photo can,
however, increase the visibility of noise, particularly in areas of shadow.
WHITE BALANCE
The color temperature of a JPEG can only be adjusted crudely, to warm
it or cool it down. With Raw, you can select any preset or specific Kelvin
value without losing quality. You can also use the White Balance color
picker to take a White Balance “reading” from a neutral area of the photo.
CONTRAST
Decreasing the contrast in a photo pushes all of the tones closer to a
mid-gray, making the shot appear flatter and duller. Increasing the contrast
pushes tones further apart, making the shadows darker and the highlights
brighter, and the colors appear more saturated.
SHARPENING
This option helps to emphasize details and reveal texture. How much you
apply sharpening varies according to how the image is to be used. Input
sharpening, applied after import, is normally moderate; output sharpening,
when you are preparing a photo for printing, is usually more extensive.
ADJUST EXPORT PRINT
Make any alterations to your photos. Export Raw photos to a more useful Creating prints is the ultimate way
