Ever wondered why I’m so fussy about ‘clean’ lighting with my coloured gelled photography? Well it’s because failing to produce cleanly lit shots with gels, simultaneously produces horrendous looking shots with gels.
When I refer to clean lighting I’m referring to the fact that I like to keep all of my lights in my scene exactly where they’re supposed to be. If I have a background light then I have it lighting the background and nothing else, when I have a hair light, I have it lighting the hair and nothing else and so on. This might seem fairly obvious but when you’re using white-light and large modifiers like softboxes, the lighting is going everywhere whether you like it or not. We simply can’t get away with being that sloppy with coloured gels.
