Tooling Special Effects

Photodesk has a reasonable selection of Special Effects available, but many of them operate only on whole images. You can't selectively apply them with the airbrush, for instance. True, you can mask off the parts of the image you don't want to affect, but this is slow, isn't interactive and feels rather clumsy compared to applying other effects.

Here's how you can locally apply a global Special Effect with any tool you like. Or at least, a very convincing facsimile thereof.

The basic idea is to copy the image on to a separate layer, apply the effect to the bottom layer, then paint transparent pixels on the topmost layer.
