Framebuffer set to AJA Kona 525/29.97 10 bit. It's definitely putting out a darker gamma. It renders correctly however. So I have preview with a Gamma +1.2 in Comubstion and remember to turn it off before rendering.
as I've got a LOT of shots and the director in the room riding me...it's a bit of a crapfest.
switching Control Panel gamma doesn't affect it - Combustion seems to be sending out YUV to the framebuffer, unlike AE which does RGB.
