I've highlighted one of its short comings.
And it is hit and miss with ETTL, because of 18% grey metering, it won't fire that much a flash behind the subject, because of the whole black lit thing. It is actually very difficult. It is much easier to have the flash off camera going off a set value in manual and ETTL the front.
Is that how you usually do it, with 2/3 OCF on stands in manual and ETTL on the hotshoe? What kind of mix of exposure, manual power levels and ETTL exposure comp?
Sorry for the questions but I'm trying to glean as much as I can about this type of lighting as there's little opportunity to practise and even less time to experiment in the heat of the moment
