As you drag the slider, hold down the ALT key (Windows) or the OPTION
key (Macintosh) to display a white overlay on the image. If you see a color appear
when you drag the slider, you are losing shadow detail in that color channel. If you see
solid black, you are losing all shadow detail in that area of your photo.
5. Drag the Brightness slider to the right to brighten the image; drag to the left to
darken it. In essence, this setting changes the midtone values of the image. You can,
however, brighten an image too much, and it will appear as though all detail in the
highlight areas of your image are lost.
6. Drag the Contrast slider to the right to increase contrast; drag to the left to
decrease contrast. This setting increases contrast by increasing the brightness of
highlights and darkening shadow areas of the image, while leaving the middle of
the tone curve unchanged. If you picture an S-curve, you??™ll get an idea of how the
Contrast control works. Note that the middle of the tone curve is determined by
the Brightness value.
7. Drag the Saturation slider to the right to increase color saturation; drag to the left to
decrease color saturation.
TIP
Select the Temperature value, and press the UP ARROW
key to increase the value by 50 degrees Kelvin, or press
the DOWN ARROW key to decrease the value by 50 degrees
Kelvin.
