Well the name has anyway.
There was a bit of confusion coming up and so a name change was in order. Originally the idea of "The Gaffer" was in reference to the job title on a film set, namely the person in charge of the lights. However, it may have been mistaken for the slang for boss and I don't want to give the impression that I'm in any way the boss of this website. That's Marc Peters' distinction.
So, what to change my forum name to?
Last week there was a delay caused by a need to re-light, during which the talent asked what the problem was. The director replied "We're waiting for Rembrandt here to finish his sodding masterpiece" which, since I'm very much a fan of chiaroscuro lighting, also known as "Rembrandt lighting" fitted rather well. Although my reply of "actually I'm more influenced by Caravaggio" went down like a fart in a spacesuit with lots of cries of "just get on with it!".
So "Rembrandt Rob" it is. An illusion to a style, rather than a claim to artistic genius.
