A person who makes highly polished wooden articles posted on a forum about the specular reflections he was getting. His home-made lightbox had two 45W lights about 4 inches from a thin tissue diffuser on either side. I stressed that he had to move the lights back and add thicker diffusers. but he had it all on a table-top and there was no way to alter the light to subject distances. Also, I think he was unsure about longer exposures. I shot this bit of polished Treen. The little hot-spot was from the front door, but using the grey cloth on the studio box as a blind, I cut that off. I posted it with the exif data and the pic of the set-up to emphasis the need for lots of diffusion.
