Oct 31, 2009 18:06 | #2 its when you stop down the power of the strobe....it dumps the previous power setting you had on. I'm sure someone can explain this better in a more technical way. but that's basically what it is. Jerome

Traditionally, if you lowered the setting, you needed to fire the strobe once to "dump" that charge so it could recycle to your new, lower setting. Otherwise, the first shot at that setting would give you too much light. "If you're not having fun, your pictures will reflect that." - Joe McNally

Great explanation, but I still fire it once after I lower the setting because I just do.
