Adjusting the brightness and contrast sliders corrects the color tone. If the original
image is too dark, too light or indistinct, use these settings to correct the image.
The method is applicable to 8-bit grayscale, 12-bit grayscale, 24-bit color (when
ColorSync™ is off) and 36-bit color images.
Adjusting Brightness
Adjust the brightness of the entire image.
This method is effective for adjusting the color tone when the entire image is too
dark or bright. However, one must be careful not to raise the respective values too
high or low to avoid creating excessive highlights or shadows.
Adjusting Contrast
Contrast is the degree of variation 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.
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.
