If I raise the RAW files I get banding. Nothing to do with the flash. But yeah, there's definitely banding if I take a black image and raise it 5 stops - something I've never, ever done before.
I used a Canon ex600RT and a Godox v860Cii to test. I tested without anything in the hotshoe, with the flash in hotshoe, but turned off, with the flash on, with flash below x-synce, and with the flash above x-sync.
The only way I can get green banding is is I have 'Silent LV Shoot.' set to 'Mode 1'
Otherwise, I just get the banding Tony (something-internet-guy) blogged about.
That’s very interesting, I see no banding without flash. But with the trigger in the hot shoe I get it at 1,65 stops or a bit of shadow lift.
It did not help for me to disable silent shutter and not using mode 1, it’s same no matter.
What I meant with a “dark shot” is a shot that’s not completely black, but intentionally dark, but usable, to give a realistic starting point for editing.
I get noise when I push 2-3-4-5 stops, and wouldn’t use that for anything, but with flash used, I can barley touch the file before I see the banding.
I’m also wondering about my sensor, I seem to get motion blur like behavior no matter what the shutter speed is and with still subjects... they look fantastic at 200% in camera, but in my computer nothing looks really sharp and most just look like a cellphone shot. Haven’t had the time to do any testing and honestly felt like everything got perfect so took a whole bunch of shots before downloading Lr and try to edit them. Lots of noise at iso 320 also... I’ll try to have a go at proper testing later today, but hard to find the time...
