Multi-imaging

I have been doing multiple exposure series of images for my art portfolio. This time I decided to apply the technique to some commercial work. I picked up the image of an optometrist's phoroptor at my annual eye exam last week thinking that I would combine it with something else to make a commercial stock photo. I had the photo of the girl's face in my files and created the optical chest charts easily in Photoshop. Then it was a matter of combining all the elements into something that made sense.
