I did a shoot yesterday and used a 580exii as a back light. The recycle time on it was way too slow. I was also using a 430ex through a softbox and it recycled really quickly but the 580 ex ii took forever. I had it on 1/1 power - will that cause the massive delay?
Also - I used a roll of paper on a background stand for a white background. Thing is, the roll kept on unwinding until I had a big pile of paper on the floor - how do you stop the paper unwinding? It's just the standard white background from calumet.
