Sigma flat and otherwise from Kirk Tuck on Vimeo.
After watching the video shot with the Sigma fp in .Mov at DPR I decided to test my camera to see just how flat a file I could pull out of the camera without jumping into Cinema DNG (raw file).
I took the camera to the bridge over Lady Bird Lake in Austin, Texas and shot some tests.
I used the camera's "neutral" profile, turned down the sharpening and the contrast in the "color" parameters and then used the manual tone curves to add +4 to the shadows and -4 to the highlights for even flatter files.
All shot at 29.97, 8 bit, All-I, 4K onto a regular V90 SD card.
I used ISO 400 as it is the camera's native video ISO. I used a variable neutral density filter to adjust exposure. We were in full sun on a very bright afternoon. No fill.
I shot with the camera for about an hour in 97 degree heat, mostly in direct sun, with no heat issues from the camera.
That's all. Thanks. KT
