I was wondering if anyone has a suggestion for a good on-line glossary for film lighting terms and equipment. The range of equipment is so overwhelming, it would be nice to have a glossary. I know I need to get some books, but I was hoping to find something online too. I've googled it, but all I find are more general "movie" glossaries. Nothing for lighting specifically that also included some of the equipment terms. Thanks!!
