So I've been looking into stobing first after seeing some of the results people have churned out and by reading thestrobist blog, a great resource. Anyway, so I went out and purchased a promaster 7500EDF flash, very comparable to the nikon sb800 (per the store guy). I also picked up an RPS studio wireless flash trigger kit 4 channel very similar to the one in this link: RPS Studio Wireless Flash Trigger Kit 4 Channel-85ft - Canoga Camera After getting my goodies home I realized that the promaster does not have a PC outlet on it. So I returned to the store and purchased a PC to hotshoe adapter similar to the one in this link: NP11131 Adorama Camera PC to Hot Shoe Adapter with Connecting Cord. So after getting these goodies home it does not work, the remote trigger light goes off when tested but no flash. What gives? Has this happened to anyone else, what can I do to try and fix it? I'm going to take it all back to the store tomorrow to try and get it all sorted out, but does anyone have any tips/tricks in the mean time to try and get it up and running? Thanks for any help you can give!
