To clean up stray pixels left inside or outside a color-based selection:

1 Choose Select > Modify > Smooth.

2 For Sample Radius, enter a pixel value between 1 and 100, and click OK.

Photoshop or ImageReady checks around each selected pixel to find any unselected pixels falling within the specified range. For example, if you enter 16 for the sample radius, the program uses each pixel as the center of a 33-by-33-pixel area (16 pixels in the horizontal and vertical directions). If most pixels in the range are selected, any unselected pixels are added to the selection. If most pixels are unselected, any selected pixels are removed from the selection.

Note: The relationship between physical distance and pixel distance depends on the resolution of the image. For example, 5 pixels is a longer distance in a 72-ppi image than in a 300-ppi image. (See "About image size and resolution"on page 62.)
