C100: is it worth using C-log with AVCHD?

ETTR most of the time means putting the histogram as far to the right as possible before the image clips, regardless of content. But like you say: no need to beat it further.

…


Indeed.
Also, ETTR is applicable to shooting RAW or LOG and it necessitates grading the footage, at least to correct the exposure. RWA files necessitates processing anyhow, and in the case of LOG files, anti-log must be applied. Thus, in those 2 cases, grading, or processing, will be done anyhow, even without ETTR.
ETTR and its' usability isn't dependent on the codec and bit-depth used.
So, yes, even C-log AVCHD 8 bit files will benefit from ETTR.

As for 'correct exposure' - 'correct exposure' is applicable only to files that are to be used as they are, as they come out from the camera, without any mandatory grading or processing. Which is why ETTR isn't to be used in such cases.

The beauty of shooting and editing yourself, is that you can treat your footage any old way you decide for yourself.
