Alister Chapman can almost be called a Sony employee with impunity, because for decades he has been explaining camera concepts from the Japanese camera factory to the entire film world. The special thing about his insights is that he often gives you more insight into the internals of Sony signal processing than Sony itself. Which is why Sony often uses him as a kind of product ambassador.
One of his hobbyhorses - the CineEI mode - is still a closed book for many filmmakers. We would describe CineEI as a kind of RAW exposure with log recording. Here, the sensor can "only" be read out and recorded in its BaseISO.
Of course, this has consequences for the correct LUT preview as well as the correct exposure via aperture and exposure time. Interestingly enough, Alister Chapman is not an ETTR advocate, but has his roots in the classic grey card exposure, which can still be found in many analogue film textbooks.
For those who also work with this exposure method, Alister&s blog on xdcam-user contains a long article about what he considers to be the correct settings for the new Sony FX6 in CineEI mode.
And also those who prefer to expose according to ETTR and own an FX6 can certainly take a good overview of the most important setting options as a kind of checklist from the article...
