There should be 2 lights in front of the table at 45 degrees and one underneath at the back. The one at the back doesn't have a soft box and this is the one you put gels on. It is easier to put a tripod in front of the table and use the zoom for your camera. The settings on your camera should be:
Shutter Speed: 1/60 Aperture: F16 ISO: 100 or 200 White Balance: Bulb |
