Hi guys. I want to make custom action figures and models. I have a 1:6 scale (12 inch) Iron Man figure and I want to 3D scan it, so that I can digitally shrink it down to 1:12 scale (6 inch) and 3D print a 1:12 (6 inch) scale Iron Man. In the reverse, I would like to use the 3D scan of this 1:6 scale figure and enlarge it so that I can make a life size Iron Man statue.

What kind of scanner do I need for this kind of work? I've read that Digital SLR camera photogrammetry works well, as long as you dust the object to be scanned with flour or baby powder. Do you agree with this? If true, this is wonderful since I already own a Canon Rebel DSLR. Thanks!
