This was done in Photoshop 7, without the use of filters.
[note]Yes, I realize Che Quevara was, and still remains to be, a controversial figure. I used him as a subject simply because I've always appreciated the classic picture of him, and I do not intend to start any discussions on him. Please, keep this to the art.[/note]

I don't know much about Photoshop (I use Corel/Jasc Paintshop Pro and Inkscape), so could you explain to me what it means to be "without filters?" Looks neat though.
Filters are "spill" effects, that are applied to entire selections. The most obvious use for them is textures, but they can produce other effects, like a "fisheye" effect. I used to rely on them heavily, but I'm realizing more and more how little control they allow, especially when used as textures.
Edit- If you want, I can send you an image that demonstrates how filters work, along with a simple explaination.
