This idea is not mine. I want to make that clear. I’m just re-posting this idea that David Hobby of Strobist.com came up with and posted to his blog.
Say you walk in to a room that you’re going to photograph for editorial, architecture, food. Whatever. The light sucks. Plain and simple, you need to add flash but you need the ambient for fill or maybe you can’t turn it off. Matching the colour of your flash to the ambient can be a pain. Especially, if you have no idea what the colour is!
