I've just updated my firmware to allow a greater range of power with my B1's when using HSS.
A curious quirk has been noticed - it may have done this with the older firmware, but I don't use HSS much so not sure if this is a new thing or not.
With shutter speeds set at a leisurely 1/100 sec I take two images of the same area. (5D Mk3)
All shits are manual shutter / aperture / ISO / colour set manually to 5600K
With the TTL Remote set to TTL, colours are reasonably as expected.
With the TTL Remote set to HSS, colours are somewhat warmer - guessing about 500-600K
Now I might expect colours to shift when I start pushing the HSS system with shutter speeds in excess of 1/200 (we can't have everything in life), but at a slower 1/100 I would assume the B1's behave with a normal flash operation.
Happens equally on both of my B1's, with exactly the same E1 firmware update, (which all went through just fine) and the C3 firmware update verified fine on the remote.
(As a side note, TTL seems a little under-exposed with the Profoto ETTL system, maybe 1/2 stop?).
Thoughts anyone? (I've got Profoto digging, but their UK office is unsure at present).
