The Brightness/Contrast adjustment lets you make simple adjustments to the tonal range of an image. Moving the brightness slider to the right
increases tonal values and expands image highlights, to the left decreases values and expands shadows. The contrast slider expands or shrinks
the overall range of tonal values in the image.
In normal mode, Brightness/Contrast applies proportionate (nonlinear) adjustments to image layer, as with Levels and Curves adjustments. When
Use Legacy is selected, Brightness/Contrast simply shifts all pixel values higher or lower when adjusting brightness. Since this can cause clipping
or loss of image detail in highlight or shadow areas, using Brightness/Contrast in Legacy mode is not recommended for photographic images (but
can be useful for editing masks or scientific imagery).
Use Legacy is automatically selected when editing Brightness/Contrast adjustment layers created with previous versions of Photoshop.
1. Do one of the following:
Click the Brightness/Contrast icon
in the Adjustments panel.
Choose Layer > New Adjustment Layer > Brightness/Contrast. Click OK in the New Layer dialog box.
You can also choose Image > Adjustments > Brightness/Contrast. But keep in mind that this method makes direct adjustments to the
image layer and discards image information.
2. In the Properties panel (CC, CS6) or Adjustments panel (CS5), drag the sliders to adjust the brightness and contrast.
Dragging to the left decreases the level, and dragging to the right increases it. The number at the right of each slider reflects the brightness
or contrast value. Values can range from -150 to +150 for Brightness, -50 to +100 for Contrast.
