Filters

Using filters

Filters let you change the look of your images, for instance by giving them the appearance of impressionistic paintings
or mosaic tiles, or adding unique lighting or distortions. You can also use some filters to clean up or retouch your
photos. The filters provided by Adobe appear in the Filter menu. Some filters provided by third-party developers are
available as plug-ins. Once installed, these plug-in filters appear at the bottom of the Filter menu.
To use a filter, choose the appropriate submenu command from the Filter menu. These guidelines can help you in
choosing filters:
Filters are applied to the active, visible layer or a selection.

Filters cannot be applied to Bitmap-mode or indexed-color images.

an error message.

Plug-in filters

You can install plug-in filters developed by non-Adobe software developers. Once installed, the plug-in filters appear
at the bottom of the Filter menu and work in the same way as built-in filters.
If you are interested in creating plug-in modules, contact Adobe Systems Developer Support.
Note: If you have problems or questions about a third-party plug-in, contact the plug-in's manufacturer for support.
