In-Depth Information
Because filters are designed for specialty purposes, the interface
you use to control filters will vary. A few filters have no user inter-
face (for example, Average, Despeckle, Facet). If a filter does not
have an ellipsis (…) after its name, it has no user interface. These
filters are fairly limited and will likely fall off your favorites list.

Fading a Filter
Most filters, however, will have some form of user interface. Some
filters have their own window; others use the Filter Gallery. No
matter which interface you use, consider selecting the Preview
option. This allows you to see the
filter's changes to your canvas before
you actually apply the filter.
Here are a few more tips about using
a filter's interface:
•
Click in the preview window and
drag your view to change the
preview area.
•
Use the + or - button under the
preview window to zoom in or
out. Additionally, you can zoom
into the preview by pressing
Command+= (Ctrl+=) and
zoom out with Command+ -
(Ctrl + -).
•
Click in the image window to
adjust the center point of the
preview window. (This may not
work in all cases.)
•
When you're in a dialog box,
fully explore it. Try adjusting all
the variable sliders one at a time.
If there's a Load button, try load-
ing presets that shipped with the
product.
•
To see t he “ before” st a t e, cl ick
and hold inside the preview win-
dow. When you release, the filter
preview is shown again.
Depending on the filter chosen, Photoshop will use a different interface.
Newer filters like Oil Paint have a very large preview area while older filters
like Diffuse have a much smaller preview area. The Gallery Effects filters
have a unique user interface that allows multiple effects to be combined
into a single operation.
