Using Rebel Xt and Photogenic Lights. Help!

[indiamb]

Hi everyone! I have been using an older photogenic lighting kit (8050 MA) with a flashmaster power unit. I have been taking very nice portraits with it for about 2 months. Recently however, I have been getting horrible results. If my camera is set on the same setting for let's say 10 shots, 3 shots are blown out, 5 of them are very dark with a blue cast and 2 appear to be correct. I am using a 420 EX on a Rebel XT to trigger the strobes. I have determined through test shots using only the camera and the 420EX that it is not the flash or camera (exposures were consistant)but the strobes. I am not sure what the problem is Please Help! I have a couple of shoots coming up soon!:confused:

Your problem lies with your chosen method of triggering your off camera strobes. The 420 emits a preflash that is triggering your strobes befor your shutter opens.

Get a flash capable of manual opperation like a 500dg super, a 550ex or a 580ex and set it to manual mode so no preflash is emitted or get you a wein safe hotshoe to pc adapter and a pc coard to trigger your off camera strobes directly from the cameras hotshoe.
