Hi I've been doing nightclub photography for a while, I use a 5d mark ii with the 24-105mm lens and 430ex ii flash gun an diffuser. Usually I Boyce the light off of the ceiling. However I am going to a bigger venue where the ceiling will be high. I'm not sure what to do in terms of how to use the flash. Also my normal settings are on manual f.4.5 2nd curtain, ISP 400 and shutter speed of 1/6
