Apple Macintosh PhotoFlash - Manual (Page 85)

You can use commands in the Enhance menu to adjust the color balance,
exposure, brightness, and contrast of an image; to blur or sharpen it; and to
remove dust or scratches. You can also use most of the Enhance commands
on selected thumbnails in a catalog.
If you are using any Enhance command on a single image and part of the
image is currently selected, the command affects only the selection. In some
cases you can use an equivalent tool in the PhotoFlash Tool palette as an
alternative to using an Enhance command. For a quick summary of the way
the tools in the Tool palette work, see the beginning of Chapter 3, “Working
With Selections.”
This chapter describes in detail how to enhance images by using the standard
Enhance commands and how to enhance selections by using the Blur,
Sharpen, DeDust, and DeScratch tools. If you have installed any Photoshop-
compatible plug-in modules in the PhotoFlash Plug-ins folder, additional
commands that aren’t described here may show up in the Enhance menu.
Such commands work much like the standard Enhance commands. See the
documentation that came with the plug-in modules for more information.
