Shadows and Highlights tool
The Shadows and Highlights tool lets you
change the shadow and highlight points of an
image.
By using this tool, you can manipulate shades so
that the Shadow point becomes the new darkest
value and the Highlight point becomes the new
lightest value. Shades that are darker than the
shadow then become black, and shades lighter
than the highlight become white. For example, if
you set the highlight point to 200, all points in
the image with a value greater than 200 will be
mapped to a value of 255, since 255 represents
the "whitest" white.
The Shadows and Highlights tool can be used
for both grayscale and color images. If you have
a limited range of grays between your lightest
and darkest point, using shadows and highlights
will have the effect of extending the range of
grays and make more detail in the image visible.
This tool is not available for use with line art or
halftone scan modes.
