Thanks. AzShooter - info on camera, etc...
These were shot with a Nikon CoolPix 8700, an older 8Mp digicam. Lighting was via an overhead fluorescent lamp diffused though draughtsman's tracing material, with some light bounced back into the shadow areas via a reflector card. Shutter speed? I wouldn't know without checking the data. I select aperture to control depth of field and let the shutter speed fall where it will. Probably a couple of seconds or so.
