I've been doing event photography for a few years, but I will be doing product photography at my new job. I am just looking for reasonably priced lighting to shoot their products. Probably between 300-600 for 3 lights with stands and diffusers of some sort. Does anyone have any suggestions for good continuous lighting kits? 90% of the shots only need to have a white background with no shadows. I may be building a lightbox to use, and a 4th light to go under it to take care of shadows.
