Working With Texture
Last night I was downstairs in my office scanning some very old photographs when I noticed that the back side of the pictures had textures that were almost as interesting as the front. So I scanned the backs, too and planned to use them at a later date.
As it turns out, last night I couldn't sleep at all. I found a self portrait I took back in May and had filed it away for a while. Note the double chin (now gone, thank you very much). There was nothing extraordinary about the original shot, but I'm quite pleased with the final results.
The overlying textures were scans from the backs of two old photographs and a battered old drum head. My only fear now is that every piece of garbage is a potential treasure. Oh my god--I'm turning into my daughter!

I accidentally just deleted a comment from you (at least, I hope it was from you) about a skull photo. And that made me come here, which I'm glad I did because I saw this self-portrait and now really curious about the textures you discovered.
I never thought to look at the backs of old photos, but it makes a lot of sense. And the effect, when applied as a texture, is really subtle yet stunning.
@Da Goddess: Thank you. Just realized that *your* comment got caught by the spam filter. I guess that makes it even. ;)
As for the textures, now that I'm looking for them, it's amazing what now seems worthy seems worthy subject material, even if it is just to add texture to another picture.
