OK, I shoot for a company that keeps me flying around the country doing interviews and I always need something to break up the background. I'm lighting with my arri kit and a couple of peppers that I still hold on to for little accents here and there. In the home studio I use the cookies on set but they are too big to travel with since I am allowed only what will fit in the arri case. What can I do to make these blank backgrounds more interesting when I don't have my kook?
