In my last video-log from the studio I was demonstrating how I did a ‘Photo-Noir’ selfie with one light and a reflector, and someone later asked why I’d referred to it as an ‘experiment’ when its a well known studio technique!

Well, what was experimental about it was that I was using a single rotolight, instead of a flash. So, what’s a rotolight, and what makes it different from a standard studio flash?
