Up to now I've been shooting my scans with a single camera (thus statues and architecture), but my goal was always to scan people. To do that I need an array (obviously). Here's the trick though, I'm very poor. I'll have to bootstrap this camera array myself which means I'll be on a very strict budget.
I've done some research on this and the Canon Powershot g11 has come up a few times as a point and shoot solution. It has remote triggering, saves the images in RAW format and has some control over exposure. The problem is price, at this time few are available on Amazon and their price is about $75 more than I can spend on each camera ($178 per camera).
I'm looking for recommendations for cheap, alternate cameras to use in a photogrammetry array. If the price can be around $100 per camera, that would be ideal.
