Setting options for painting and editing tools
You set options for a painting or editing tool in the options bar.
Selecting a blending mode
The blending mode specified in the options bar controls how pixels in the image are
affected by a painting or editing tool. It’s helpful to think in terms of the following colors
when visualizing a blending mode’s effect:
•
The base color is the original color in the image.
•
The blend color is the color being applied with the painting or editing tool.
•
The result color is the color resulting from the blend.
To select a blending mode for a tool:
Choose from the Mode pop-up menu in the options bar.
Normal Edits or paints each pixel to make it the result color. This is the default mode.
(Normal mode is called Threshold when you’re working with a bitmapped or indexed-color
image.)
Dissolve Edits or paints each pixel to make it the result color. However, the result color is a
random replacement of the pixels with the base color or the blend color, depending on
the opacity at any pixel location.
Behind Edits or paints only on the transparent part of a layer. This mode works only in
layers with Lock Transparency deselected and is analogous to painting on the back of
transparent areas in a sheet of acetate.
Clear Edits or paints each pixel and makes it transparent. This mode is available for the
line tool (when fill region is selected), the paint bucket tool , the brush tool ,
the pencil tool , the Fill command, and the Stroke command. You must be in a layer with
Lock Transparency deselected to use this mode.
Darken Looks at the color information in each channel and selects the base or blend
color—whichever is darker—as the result color. Pixels lighter than the blend color are
replaced, and pixels darker than the blend color do not change.
Multiply Looks at the color information in each channel and multiplies the base color by
the blend color. The result color is always a darker color. Multiplying any color with black
produces black. Multiplying any color with white leaves the color unchanged. When you’re
painting with a color other than black or white, successive strokes with a painting tool
produce progressively darker colors. The effect is similar to drawing on the image with
multiple magic markers.
Color Burn Looks at the color information in each channel and darkens the base color to
reflect the blend color by increasing the contrast. Blending with white produces no
change.
Linear Burn Looks at the color information in each channel and darkens the base color to
reflect the blend color by decreasing the brightness. Blending with white produces no
change.
