Hi, I have the Demp-it and diffuser and love it. I'm shooting this wedding next Saturday under this huge pavilion. The problem I'm having is when I have the Demp-it and diffuser on I think I'm losing a lot of wasted flash just going straight up because I'm have to either raise my ISO way up there and having to the adjust the flash level Manually so it will through enough light. Also this is at 1/250. Also this is with the Flip-it totally forward. I don't want to use direct flash because I really don't want that look. I do have the Stofen diffuser but I'm wondering if I will run in the same problem. Let me add- absolutly no way to bounce flash. The ceilings are 25 to 30 ft. high and no walls to bounce flash off either. Any solutions??? Thanks!!
