Brightness and Contrast tool (Native Color Mode only)
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. For Lab color images,
brightness and contrast applies only to the L (Lightness) channel.
Drag these sliders
to change the
Brightness and
Contrast
• Brightness: The Brightness control lets you change the brightness setting. Too
much brightness can make an image look washed out, while very low
brightness levels can make an image looked very dark.
• Contrast: The Contrast control lets you change the contrast setting. Too
much contrast can make an image look like a photocopy of a picture with
little or no gray shades. Too little contrast can make an image look dull and
flat.
