Great pic Harry. Always interested in your work as lighting is always top notch.
It is Foxy that is edging into using manual. I can only think in manual and found my SB80-DX instruction manual hard work so gave up on it. Only use DTTL for behind the scenes snaps.
I think manual can appear quite daunting at first, so an easier starter route is ITTL, DTTL, ETTL. Once you are using a flashgun at full bore to get a correct exposure, then you are essentially in manual as metering is having no effect, and only moving the light relative to subject or upping ISO will affect exposure in auto.
The difference between us Harry, is I only have 4 flash guns and 2 slaves and 1 remote cord. Two of the flashguns are battery eaters so most of my shots are with 2 guns only. I will use one of the battery eaters only if I have to.
Foxy's kit is not very technical. Having seen the brollie, it is a 2 in 1 job. It is just that Foxy is using it in a novel way. Perhaps he will post an explanation of it.
