Brightness & Contrast
The Brightness & Contrast tool lets you control the brightness and contrast levels of the entire
image. Increasing the brightness makes all tones in the image lighter. Contrast, on the other hand, is
the range between the darkest and lightest shades in the image, and increasing the contrast makes
greater separation between the darkest and lightest areas of the image.
Note: Individual channel adjustments for brightness and contrast are not supported. For RGB color
images, the same effect applies to all channels.
To use the Brightness & Contrast tool:
Drag the scroll bar on the Brightness or Contrast control to change the settings. Take note of the
following:
• Too much brightness can make an image look washed out, while too little brightness will make
the image look dark.
• Too much contrast will make an image look like a photocopy of a picture, with little or no gray
shades left. Too little contrastwill make the colors in the image look dull and flat.
