I ran into some difficulty when using S-log3 on the Sony FS-7 because my images always seemed to be under exposed, even though I was using a light meter. Part 1 of this tutorial series was mainly about looking at why lenses don't behave ideally and how to use an 18% gray card to get "correct" exposure. In part 2 I wanted to eliminate the need for a gray card - which I knew would just get lost or destroyed on set - and start to be able to trust my light meter again.
So I read the Sekonic manual and it gave me a way to compensate the exposure reading. Then I went into Video Gear and lit up a gray chart and found the correct compensation offset for each of my lenses. The end result is that I can use my light meter again with more trust - because it's been verified! That's what this video is about.
Most of my lenses are about half a stop darker than ideal. What really surprised me was that the optically excellent 21mm lens is almost a stop darker than ideal! I ran into this problem in post on the car mount video and the results of the color correction was frustratingly as good as I could get it. I won't have that problem anymore.
So here's part 2 of 2 of our log gamma exposure tutorials - shot in S-log3 on the Sony FS-7.
