Antonia, is that approach an attempt keep equipment costs down? SONY and JVC have pretty high quality digital HDTV motion cameras for well under $10,000, am not sure if the SLRs you are talking about can beat them in price and quality. I investigated digital SLR, at least in the under $2500 range, and was told that you can't actually just open the shutter and shoot a steady stream like you can with almost every other digital still camera; the mirror is in the way. Therefore, there is a "recoil" or "reset" factor for a digital SLR. If you need to achieve 24/30 FPS, you'd need more than one SLR. Now the higher-end digital SLRs may get past that issue. As you can see, I've been thinking along these lines. A cool digital SLR that could take 1-3 minute film snippets, the 'disarming' factor of shooting a film on a still camera, etc. etc. Add to that "motion matching" software that can take a succession of stills and generate a 3D model.....possibilites abound. ::::: Opera :::::
