I'm not a big one for highly-processed photos, but every now and then a style will take my fancy and I will want to figure out how it is done. At the moment, it is the smeary, blurry, textured grunge effect.
Examples:
Thomas Devaux http://www.thomasdevaux.com/gallery/gallerydevaux0.php
Nicholas Alan Cope's portraits of Marilyn Manson http://previiew.com/home/newsboard.h...%20Alan%20Cope
So far, I can see that it is a very painterly effect, being as much digital art as photography. There seem to be layering of multiple images (a "double exposure" effect) as well as use of selective blurring, perhaps a texture layer or two.
Any other ideas on the technique behind this? I am always up for a challenge.
