Common paint tool settings in the Paint panel
To use the Paint panel, first select a paint tool from the Tools panel.
Opacity
For Brush and Clone strokes, the maximum amount of paint applied. For Eraser strokes, the maximum
amount of paint and layer color removed.
Flow
For Brush and Clone strokes, how quickly paint is applied. For Eraser strokes, how quickly paint and layer color
are removed.
Mode
How pixels in the underlying image are blended with the pixels painted on by the Brush or Clone stroke. (See
Channels
Which channels of the layer the Brush stroke or Clone stroke affect. When you choose Alpha, the stroke only
affects opacity, so swatches are grayscale. Painting the alpha channel with pure black has the same result as using the
Eraser tool.
Duration
The duration of the paint stroke. Constant applies the stroke from the current frame to the end of the
duration of the layer. Single Frame applies the stroke to the current frame only. Custom applies the stroke to the
specified number of frames, beginning with the current frame. Write On applies the stroke from the current frame to
the end of the duration of the layer and animates the End property of the stroke to match the motion with which the
stroke was drawn.
When you have a paint tool active, you can press 1 or 2 (on the main keyboard) to move the current-time indicator
forward or backward the number of frames specified by the Duration setting in the Paint panel.
