After seeing some of the results on here i've decided to invest in some flashes and remote triggers, thing is aside from my sigma ef500 i've never used flashguns. I can bounce the sigma, but i want the flexibility of remote flashes. Thing is, i dont know where to start, octaboxes, softboxes, radio triggers etc etc.
For a budget of around £500 sterling, what could/should i be looking at?
All advice greatly appreciated
