I have my speed light off camera on its own stand. It is connected to my Paul Buff Alien Bee light so will flash when the Alien Bee flashes. This worked for awhile, but now I'm having trouble with the speed light not flashing or regenerating when attached to the Alien Bee. It works just fine when I attach it to the hotshot on the camera, but when I remove it from the camera, place it on a stand, and attach it by the cord to the back of the Alien Bee, it does not flash. What could be the reason for this? I will mention that I changed the batteries in the speed light, thinking that could be the problem. I'm using the speed light as fill light for the darker shadows on the face, and I really need to get it working. I don't know what to try. I did post a question on the Paul Buff technical forum, so I hope to get an answer back from them. But I know there are a lot of smart people here, so I thought I'd post the problem here as well. Thanks so much!
