I'm putting this into scraps because it's really not mine, per se. I didn't take the photo, and they're not my hands. These are taken from one of the model packs from 3d.sk. I did manipulate the top and bottom shots so that they overlay perfectly. If you take one and move it over the other, they line up perfectly.
I scaled stuff, and used liquify and transform to adjust it, so theoretically, it's a photo manipulation, and I pay for 3d.sk and have the rights to use the images as I see fit, and royalty free, so this is me using them.
I'll also use this space to once again rant about how much I effing love 3d.sk. Yes it's a pay site, but it's worth it you cheap kids. If you're in school, and your school doesn't have an account with them, just go in with some of your classmates and pay for a subscription. It's amazing.
Anyway - feel free to use this as reference and what not.
