Just playing at doing test scans, same subject matter, but dark outside. I decided to recalibrate with the lights off, and the lower light levels appear to be working. Using medium subject option, with low res to get the "texture" option, and here's some screenshots. I think you'll agree the "quality" is better.

One pass, then two pass

PS I found using the turntable, as it does 8 steps by default to put the main side at around 45º to the camera, that way you get three passes of good resolution...makes difference, anybody else think the same?
