The four pieces I have submitted are samples of my medical illustration work. They are general anatomy images, created in Adobe Photoshop, and are aimed at a general audience. (e.g. use in textbooks, education) 4x6 - giclee print.
"I needed a very high quality print to enter in a photography art show. I had my photograph printed at a superb printer, using a very expensive machine. I also ordered the same print through Photobucket. And yours was superior!"
