Digital Photography Goes Mainstream

"We've come a long way since we made the move to digital back in 1993," says Jon Keeling, director of PhotoArt. "Our original camera, which costs upward of $40,000 fully outfitted, had a mechanical filter wheel mounted in the camera lens. During each shot, the wheel would advance through three passes to capture red, green, and blue. Then the software would merge the three image 'layers' together."
