These two did another project where they figure out the lighting of an artist in CG. This one is on Andrew Wyeth. My big take away was to start using modifiers on my lights. Kind of a forehead-slapping moment.
When I light stuff in the studio the first thing I do is decide what kinda modifier I am gonna put on the light. Strip box with a grid? Projector with a grid? Beauty dish? Well, in CG I just grab a naked light and start aiming it like a scrub. It will be interesting to mess around with diffusion and more modifiers.
