Use the Save and Load buttons to save and reuse custom filters.
Apply a Custom filter
1 Select an image, layer, or area.
2 Choose Other > Custom from the Filter menu.
3 Select the center text box, which represents the pixel being evaluated. Enter the value by which you want to multiply
that pixel’s brightness value, from -999 to +999.
4 Select a text box representing an adjacent pixel. Enter the value by which you want the pixel in this position
multiplied.
For example, to multiply the brightness value of the pixel to the immediate right of the current pixel by 2, enter 2 in
the text box to the immediate right of the center text box.
Note: To avoid turning the image completely white or black, the sum of the values in the matrix should equal 1.
5 Repeat steps 3 and 4 for all pixels you want to include in the operation. You don’t have to enter values in all the text
boxes.
6 For Scale, enter the value by which to divide the sum of the brightness values of the pixels included in the
calculation.
7 For Offset, enter the value to be added to the result of the scale calculation.
8 Click OK. The custom filter is applied to each pixel in the image, one at a time.

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 unless the developer has specified another location.
If you are interested in creating plug-in modules, contact Adobe Systems Developer Support.
Important: If you have problems or questions about a third-party plug-in, contact the plug-in’s manufacturer for support.
