heyya POTN,
I was wondering if it was possible to fire the 430ex if it wasnt directly facing the 580ex?
I would like to start shooting people / models, and I saw jacobthephotographers shoot when he just used a 580ex and 430ex.
Although I haven't had the funds to acquire a 580ex, I would like to eventually achieve a similar setup as he had. 580ex on the off camera shoe cord, and a 430ex on a light stand.
Ideally id like to have the 430ex on light stand, and to add an umbrella to possibly diffuse the light even more.
My question is, if the 430ex's reciever is pointing away from the 580ex's transmitter (ie flash is pointing towards the umbrella), will the flash still fire? Or will I run into problems?
In addition to that, if the 580ex is on ettl, will my 430ex fire accordingly, or will it have to be manually set?
Also, is there any way to achieve a similar setup without shelling out $300+ for a 580ex? I've looked into the sigma dg500 line of flashes, but I might as well buy the 580ex and have a peace of mind. Could I maybe have my 430ex on the offshoe cord, and have it wirelessly trigger something like a vivitar 285?
Thanks for any help! 
Eric
