2 x SpeedLite problem
I think that should be simple and easy but it wasn't...
Recently i got 2 speddlite 580 and tried to use them both as a light source.
One on camera and One off camera but it didn't work.
The one on camera was Master (ETTL) and off camera Slave (ETTL)
When I shoot 2 flashes goes off but you can see light only from one on the photo, the one on camera was giving the light.
When I set flashes MANUAL they both give light.
What Im doing wrong. Can I use both flashes in TTL as a light sources or not.
