Retouching image areas by using brushes

You can retouch images by applying brushstrokes. Some retouch brushes mimic photographic effects, while others change pixels based on their lightness, saturation, hue, or color values. Some retouch brushes create effects that are similar to those produced with the color-correction commands. The retouch brushes are described in the following table.

Brush	Effect
Lighten/Darken	Increases or decreases brightness; affects the RGB or Lightness value of pixels
Dodge	Lightens and brings out details of areas that are in shadow (mimics the traditional photographic darkroom technique of holding back light to produce lighter areas in printed photos)
Burn	Darkens areas of the image that are too light
Smudge	Spreads color and image details from the starting point and picks up new color and image details as it moves, as though smearing paint
Push	Spreads color and image details from the starting point but does not pick up any new color or image details
Soften	Smooths edges and reduces contrast
Sharpen	Heightens edges and accentuates contrast
Emboss	Causes the foreground to appear raised from the background by suppressing color and tracing edges in black
Saturation Up/Down	Increases or decreases saturation; affects the HSL value of pixels
Hue Up/Down	Increases or decreases hue; affects the HSL value of pixels
Change to Target	Changes pixels based on a characteristic of the current foreground color on the Materials palette: color, hue, saturation, or lightness • If you choose the color as the target, the brush applies the foreground color without affecting the luminance. • If you choose the hue, saturation, or lightness as the target, the brush applies the hue, saturation, or lightness value of the foreground color without changing the other values.
