Photographers produce two-dimensional images of three-dimensional objects and scenes. What fun, to take those flat pictures and re-create them with actual depth!
This process of creating three dimensional images is called Paper Decoupage. It involves printing multiple copies of the image, cutting out sections, carefully tinting the edges, and layering the pieces with spacing in between to build the 3-D artwork.
I use this method to emphasize the perspective of the images and give them a tactile quality people want to touch, especially when an item extends out over the mat. It also allows me to combine several related photographs into a single 3-D composition.
I still make 2 dimensional photographs but find they must be of a compositional quality creative enough to be as interesting as the 3 dimensional ones.
