I can't believe that I haven't mentioned David Hochbaum in this blog yet. The man does some seriously illustrative and creative work!!! I love the story telling nature of his pieces.
"David Hochbaum's art is the construction of paintings built on photographs and images that are not only the contemplation of human behavior, but also a reaction to history, astronomy, sex, and iconoclastic symbols....David Hochbaum's medium is built from a melange of wood, metal, and paper, both photographic and printed matter. Each work is painted with oil, acrylics, varnishes, pencils and inks. These images are layered physically as well as historically, combining the figurative approach of the 19th century photographer with the medieval alchemist projected through the eyes of a 20th century cubist."
There is a decent explanation of his technique on his site. He uses posed photographs as his basis for these beautifully haunting and involved stylistic works. I am not certain about his collage techniques, it's all so mysterious.
