A fractal is a fractal, whether post-processed or not, so mine always go into the fractal gallery. I'm a firm believer that using Photoshop, etc., to enhance an image only changes it from a fractal to fractal ART. Besides, everyone gets a chance to see what's posted, as they are available in the new posts gallery.

Using a fractal in Bryce, etc. as a texture map may be a different story, as the fractal is a component of a larger work and not the focus of it. But to my mind, that's not 'post-processing'.
