I have not kept up with the innovations in photography since I graduated in 1988. Back then I used completely manual 35mm Olympus SLR's. I do have a digital camera now. In fact, I have owned several. However, I have never used the available technology to do anything other that shoot a simple image. No manipulation of any kind.
Dave, on the other hand, is a professional who does weddings, portraiture, commercial, editorial, and advertising work. He is also a talented artist both as a photographer and a painter. He graciously let me look over his shoulder when ever I wanted throughout the day. He also patiently explained some of the cool processes he uses to achieve his final images.
