About 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. (See "Using plug-in modules" on page
Note: If you have problems or questions about a third-party plug-in, contact the plug-in's
manufacturer for support.
Using filters
To use a filter, choose the appropriate submenu command from the Filter menu. These
guidelines can help you in choosing filters:
The last filter chosen appears at the top of the menu.
•
Filters are applied to the active, visible layer.
•
Filters cannot be applied to Bitmap-mode or indexed-color images.
•
Some filters only work on RGB images.
•
Some filters are processed entirely in RAM.
•
Gaussian Blur, Add Noise, Dust & Scratches, Median, Unsharp Mask, Solarize, and High
•
Pass filters can be used with 16-bit-per-channel images, as well as 8-bit-per-channel
images.
Previewing and applying filters
Applying filters—especially to large images—can be time-consuming. Some filters let you
preview the effect before applying it.
To save time when trying various filters, experiment on a small, representative part of
your image.
To preview and apply a filter:
1 To apply a filter to an area of a layer, select that area. To apply a filter to the entire layer,
leave the image unselected.
2 Choose a filter from the submenus in the Filter menu. If a filter name is followed by
ellipses (...), a dialog box appears.
3 If a dialog box appears, enter values or select options.
