I have been shooting alot of events and clubbing shots for these recent years. My flash is on most of the time on my camera. Till now, I am still looking for way to have a nice diffuse light on my flash.
Apart from this, the nikon CLS do a really great job in this system. I can control my flash, TTL, manual, or AA on my comander flash. Unlike what I usually do last time, I use manual in all flash, and triger it with PC cable.
