in my university, we can rent out lighting equipment to use for filming video. the kit includes a fill light, a key light, and a back light. the fill and key lights have an umbrella and a soft box to put over them. can't you use this same kit for shooting portraits with a digital camera inside too? The man in charge of renting the equipment out claimed he couldnt give me the equipment becuase the lights are for HD video cameras and ONLY work with that, but i don't understand that if im trying to take basic portraits for an introduction to photography class and want to use these lights why they wont work. any help?
