I am trying to trigger a studio strobe with the 600D flash or a wireless speedlite430exII
In both cases, and with both flash outputs set to manual, the camera still fires the flash twice, once before the shutter opens, and once to expose.
why is it still firing twice if I haven't selected E-TTL II mode? this double flash is obviously triggering the strobe early.
Any work arounds? I do have a set of cheep wireless triggers, but this would mean loosing the built in functionality of the 600D to wirelessly trigger the speedlite, plus I dont want to buy a hotshoe sync for the wireless trigger.
