Advaitin please confirm.
I too would not have guessed wireless with the combo of HVL20 and i40.
I will check it again tomorrow when I get out of the hospital.
But again I ask, even if it is not radio and is optical, how can I eliminate
exposure contribution from the on-camera, e.g. the HVL20, from the overall
exposure?
I would think the HVL20 so underpowered that its contribution at distance
will be minimal.
Yeah I'm always scheming owls

I don't use flash much. Sometimes with a better beamer for birds. When I was working I used multiple dumb flashes and electric eye triggers and a minolta flash meter for combined readings. All that stuff is gone. If I have to have a flash these days I use a shoe mount and bounce it or use a softbox type diffuser. If I had to, I suppose I could set an off camera rig, but I'd want the instruction manuals close by. I used the beamer for the owls here, no flash for the owl in Bulgaria. If your flash on camera is a master and your second flash is the main but slaved, you just need to experiment to see how much you can diffuse or turn the head to still set off the second flash. Just off the top of my head.
