Does anyone have any tricks (read: made the mistake) of taking a picture where a person legitimately appears to be an amputee? I need to this effect with legs at the knee for one shot, and a hand at the wrist (if possible) for another. I was thinking about just folding a leg back, but that limits the angle. I'm hoping someone has some more advanced tricks, or even just specific suggestions about folding the limb back. I failed finding real amputees that would fit my needs, but I did look. Suggestions?
