I want to get a bit more into using my 580EX-II flash and have been looking at the plethora of diffusing options. So far I have resorted to the ol' bounce off the nearest object but want to get into the concept of off camera, direct flash and control over ambient and shadows etc.
So my questions is what would you recommend for a relative beginner for both on-camera diffusion and off-camera diffusion?
I was considering the Lumi Softbox III as an introductory softbox but it is a pretty small source so perhaps i'd be better going for a shoot-through umbrella?
Thanks in advance for any help,
