Step 3 • Adjusting Images
Adjusting Brightness
This method adjusts the brightness of the entire image, which is effective for
images that are too bright or too dark overall. One must be careful, however, not
to raise the respective values too high or low to avoid creating excessive highlights
or obscuring shadows.
Brightness = 128 (Standard) Brightness = 190 Brightness = 80
Adjusting Contrast
Contrast is the degree of deviation between light and dark areas. Raising the
contrast accentuates the difference between the light and dark areas. Lowering
the contrast reduces the difference between the two.
Contrast = 128 (Standard) Contrast = 170 Contrast = -100
Raising the contrast of pictures with a blurred focus is effective in adding clarity to
the image. Raising the contrast too high, however, will obscure the dark portions
or create excessive highlights.
