Hello all, I have a Canon EOS Rebel T3 12.2 MP CMOS Digital SLR with 18-55mm IS II Lens and will be taking a photo of an all black, tactical shotgun. I have 2 lights, a green screen, and a roll of white thick stock paper. I'm a complete newbie to photography and not sure how to maximize this small space with minimal supplies to take the highest quality photos. Where should the table go in relation to the window? Should I cover the window to black out the room? What are the basic no-brainer settings I need to have on my Rebel T3 for such a shot? All suggestions are greatly appreciated!
