I met German photographer, Tilo Gockel / fotopraxis, during one of his visits to New York. Seeing this photo on his blog recently, immediately reminded me of my recent first attempt at playing with colored gels and flash .. except that he did it better! So I asked Tilo if he'd translate his article for us into English. It's always good to get another angle on doing something. There are a couple of good tips and ideas in there. Thanks Tilo!
