Thanks for the comment. We use 2 (sometimes 3) cameras (on tripods, of course), macro lens, 18-55mm; 70-300mm & other lens. Flash units with sound triggers. Then we switch the setup, colors, etc around to get different effects. We take hundreds of photos experimenting like this. Many shots are too dark, blurry, timing off and so forth. But we do get a few that turn out.
