One project I am considering is where I show an image of one of my subjects holding a large photo I have taken of them. Doing it with a real print is both expensive and a bit troublesome because the print will often be a bit reflective and does not photograph well (tends to look a bit flat).
I wanted to try an approach that involves photo compositing. I had my subject hold a piece of foam core so that the hand position on the "print" looks "normal". I also wanted the background to look a bit dark to give the "print" a bit of "pop", so I used a technique sometimes called "focused flash". Here I underexposed the background by 1 - 2 ev and used off-camera flash to light my subject so that she was properly exposed.
Here is the "final" completed version:
This is the actual image before photo compositing.
