I've been given an assignment to photgraph about 80 x-rays. They are going to be positioned on a x-ray light box. I have a Canon 20D camera. The lens I have are a Canon 80-200mm (4.5-5.6) UV filter, a Canon 28-105mm (4.0-5.6) UV filter, and a Canon 50mm (1.8) no filter lens. I'm not familiar with any shooting other than the camera being on automatic, except manual focus. If anyone can help me, it would be greatly appreciated.
