Editing filters
Applying Image Effects 61
The core objective of filter layers is to host filters applied to your image. Once a
filter is applied, it's likely that you may want to edit it at a later date.
To edit a filter:
1. Double-click the filter entry, e.g. Gaussian Blur.
OR
Right-click the filter and select Edit Filter.
2. The filter can then be edited via dialog or Filter Gallery. Adjust the filter and
click OK.
Using filter masks
In an identical way to layer masks (see p. 27) you can apply a mask to a filter
layer. However, masks can additionally be used for selective filter control for
image correction or artistic reasons. These are called filter masks, which limit
the influence of any applied filter(s) to that masked region only. Filter masks are
applied either automatically (from a selection existing before applying a filter) or
manually (after you've applied the filter) to a filter group (but never to an
individual filter).
See Using masks (see p. 27) for more details on masking and
masking controls.
