"if you shoot your own photos there are several advantages. Higher resolution. Color and lighting consistency" Thats a big assumption to make. I'm describing technique ASSUMING that people don't own a professional photo studio or even a camera. "with low-resolution source material, how accurate is your clone going to be?" You'd be suprised. I don't consider any of the source materials I've worked with so far to be Hi-Res. Maybe Medium-Res at best. Obviously, the better the source material the better the finished product. But I'm trying to show people how to get maximum results with minimum resources. Ideally, I'd love to be working at ILM with the latest in cutting technology. I'm not and neither are most small business owners or freelance artists. Doesn't mean you can't get some impressive results, you just have to be resourceful.
