Messing around with gels and light and trying to maintain control of both. The Under-lighting is done by creating a light box from a fish aquarium--to do so...One light is left shooting through a blue gel into the aquarium which has a piece of white foam board at a 45 angle. All other sides aquarium except shooting surface are covered with card stock. Diffusion film is below the perforated metal sheet on open side of glass aquarium. Second light from top has an orange gel thru diffusion film. Couple bits of black card keep the chrome wrenches dark, couple bits of white card camera right fill on the hardware and tiny bit of light inside the wrench box.
