Contrast difference: Burned-in LUT v SLog w/ same LUT

PostFri Sep 15, 2017 12:03 pm

Here are two anomalies that I observe and don't understand...can anyone explain?

When I burn in a LUT in-camera and then compare to the same LUT applied to SLog in post there is a very small increase in contrast to the latter.

LUT in-camera:

LUT applied to SLog in Resolve:

And having noted that 'Offset' in Resolve needs setting to 4.45 to compensate for the 500ISO (2 stop push) when I use Resolve Live feeding the camera's image live and use the same Offset setting of 4.45 the exposure doesn't match:

An Offset setting of 1.35 is needed:
