Erasing similar pixels
To use the magic eraser tool:
1
Select the magic eraser tool ( ).
2
Enter a tolerance value. This defines the range
of colors that can be erased. A low tolerance erases
pixels within a range of color values very similar to
the pixel you click. A high tolerance erases pixels
within a broader range.

Select Anti-aliased to smooth the edges of the
area you erase.
4
Select Contiguous to erase only pixels
contiguous to the one you click, or leave
unselected to erase all similar pixels in the image.
unselected to erase all similar pixels in the image.
5
Select Use All Layers to sample the erased color
using combined data from all visible layers.
6
Specify an opacity to define the strength of the
erasure. An opacity of 100% erases pixels to
complete transparency. A lower opacity erases
pixels to partial transparency.

Using the background eraser tool
The background eraser tool lets you erase pixels on
a layer to transparency as you drag; this allows you
to erase the background while maintaining the
edges of an object in the foreground. The
background eraser samples the color in the center
of the brush, also called the hotspot, and deletes
that color wherever it appears inside the brush. It
also performs color extraction at the edges of any
foreground objects, so that color halos are not
visible if the foreground object is later pasted into
another image.

If a brush is too large to fit in the palette, it appears
as a smaller brush with a number indicating the
