Retouching and restoring images 247

ForeSwatch — erases all pixels that match the current foreground

color on the Materials palette

• Limits — specifies whether erased pixels are adjacent to each

other. This control has the following options:

Discontiguous — erases all pixels in the tool’s path that match the

sampled pixels, even if they are nonadjacent. You can use this

mode to correct areas in which the background shows through

holes in the image.

Contiguous — erases only contiguous pixels that match sampled

pixels. You can use this mode when the background pixels are of a

color that is similar to that of the edges of the object you want to

isolate.

FindEdges — uses the edge information to restrict the erasing

Auto Tolerance — determines the tolerance based on the pixels in

the tool’s path. The tolerance may change continuously as the

tool moves over different parts of the layer. You can unmark this

check box to specify a Tolerance setting.

Use all layers — samples data from all layers merged together.

Only pixels in the current layer are erased. To sample data from the

current layer only, you can unmark the check box.

Ignore Lightness — ignores sharp differences in color lightness

and saturation. You can mark this check box when the colors in

the object that you want to isolate are strongly saturated and the

background is unsaturated, or vice versa.

Should I use automatic or manual tolerance?

You should start by marking the Auto Tolerance check box. If you find

that too much or too little is erased from the image, you can unmark

the Auto Tolerance check box and increase or decrease the value in the

Tolerance box.
