"If you don't have a roll of gaffer's tape in your studio, put down this book, go online and order a few rolls right now. Not duct tape. Not electrical tape. Graffer's tape! It's one of those things that once you have it, you'll wonder how you got through a shoot without it (ask any studio photographyer). You'll use it for everything from holding grid spots in place, to fixing a gap in softbox, to keeping things together when doing product shots, to... I could go on and on."
