When Michael, whom I know for being a great improviser and really not camera-shy but a tad crazy, asked me "do you have the fast frame thingy on your camera ?" I didn't know, by answering Yes, I had signed up for a free work out !
A Grey background, a striplight & a big poly at the back and a magnum dish and a large softbox at the front, and I was ready to follow Michael in his performance.
