It appears quite a few users would like to purchase this proposed alternative version, with a relative consensus on features...
I?ve also have this kind of system. But I?m using for a whole body scan about 74 cams ;-) with 12 cams, you can ony capture the bust of a person.
Some more on how I take photos for use in PhotoScan. Also see my post above.
Aperture setting usually is a compromise between maximizing depth of field with smaller aperture size (larger f-stop number) and decreasing sharpness due to diffraction with smaller aperture. Typically I use f 8 to f 16. Important - sensor size has a major impact on aperture effects. With the smaller sensors used on compact cameras the preferred aperture will probably be around f 4 to f 5.6.
My subjects are inanimate to I frequently use a tripod. Using a tripod allows longer exposures, and I also find that when using a tripod the camera locations generally are more evenly spaced with the camera direction more consistent. I usually use an ISO setting of 100 or 200 though if needed to keep exposure times short I occasionally go to an ISO setting of 400. A very few times I've used an ISO setting of 800 when the alternative was not to get usable photos.
When the camera is on the tripod Shutter speed is what ever it needs to be given the aperture and ISO settings selected. When I'm hand holding the camera I use a minimum shutter speed of 1/25 second and prefer to be faster. This sometimes requires an increase in ISO or a larger aperture (smaller f-stop number).
