Lighting for some people is scary. There's all sorts of talk about color temperature and ratios and a million different light modifiers. The hardest part is just getting started. My approach has always been that of continuous experimentation. The idea is to start with one light setup and make small adjustments little by little until after an hour of playing you're doing something entirely different than when you started. This morning's fun started with me using a couple of umbrellas to test light falloff and feathering, and as usual, it was 10am and I was too busy playing with lights to care about things like showering before pictures.
Anyway, from that starting point, I slowly added one background light, then two, then dialed down the main lights, then colored the background lights, then eliminated the front lights all together, and ended up using bare speedlites filtered to create an ever changing mix of colors.
Lesson for the day - Incremental changes can yield drastic results. Go experiment with something!
