where can i get lightboxes that are suitable for backlighting fine art photographic prints in an exhibition?
I have found some websites that sell light boxes but they seem to be only for big companies ie for outdoor signs but I cant seem to find somewhere that supplies them for art or photography purposes
Smaller light boxes are sought-after items and sell well on eBay. (Look under Cameras and Photo > Darkroom and Developing). Sometimes you can find good deals in X-ray viewers at junk shops of when a hospital sells surplus stuff.
