You've all heard of photoshopping, that ability to enhance a picture/change a picture so that it looks almost real. I've done that before. Here's my picture of Natalie Maines of the Dixie Chicks with Saddam Hussein.
Looks like they're having a good ol' time, right? Sure, except that it never happened. In the first picture, that's actually Maines with her husband, but I photoshopped Hussein's face in there, and but for the pink of Saddam's ruddy skin into the lilly white of Maines' husband's chest, it might pass as legitimate.
I did this one too - it's more realistic. This kind of thing can get you into trouble, so I don't do it much.
I stopped at my grandmother's house over the summer and she asked me if I could blend a friend's two family photos together so that the resulting single picture looks like a family portrait. Sure, I told her. No problem.
Hmm... notice the darkness around the edge of these 70's photographs. Notice too that to blend them together, I'll have to make an arm where none existed before. I can't just stick them together.
I managed to do it by copying bits of the father's fabric and molding these bits into a sleeve. A little shade here, a little highlight there. I think it comes off fairly realistic.
So if you ever have to do something like this, try that approach. I printed this out on photo paper and sent it to her. She plans to give it to a friend of hers, the mom in the photo. Kind of cool to be able to do this.
