Here’s a photo of my first light box. It’s made out of white foam core, and top is parchment paper. The whole thing is held together with T-pins and disassembles for storage. The lights are blue bulbs, available from your friendly local photo supply house. The two side lights are 250 watts, the top is 500. The top light is hanging from a ceiling fan using a terribly jerry-rigged set up involving some coiled copper wire and two hangers — one over each of two fan blades!
I built this based on the excerpts at www.ganoksin.com from Charles Lewton Brain’s book, Small Scale Photography. One quick note: 1. never touch blue bulbs with your hands, use cotton gloves or socks.
