Gafpa LUTs and Flog2

VaBr

Hello,

I currently have a Fuji XT5 (same sensor as XH2) and I’m interested into your LUTs made for F-Log2.

Which zebras percentage should be set on the camera for exposure so that your LUTs then work well in Resolve?

Thanks

VaBr

Also, could you provide the node workflow that should be respected (WB if needed, exposure if needed, LUT, how many CST with their values) please?

Note: I tend to shoot ETTR with zebras set at 85% (which is the maximum value recommended by Fuji to expose FLog2).

Thanks.

hey thank you for your question. 85% is a good level to see full clipping. Basically a camera captures light in linear, which is then transposed to log, the brighter you shoot the less noise, but if you shoot too bright apart from clipping you might loose some details due to the nature of a log curve, but this is marginal. For node flow, I would always do denoising on the first node, then on the 2nd do a technical pass white balance, not creative but just scene based, and use the offset slider if the exposure is too crazy, on the third note add the log to log node, and if you keep it simple add a node behind for some exposure adjustments like highlights etc and after that a color space transform from arri log c to rec709 . Make sure nothing is dramatically clipped or out of gamut, and do some primaries after this pass if needed
