Re: My experience with log

I see some nice, replies: Thank you.

Thinking about about ISO as a mapping is a useful idea. And I see some replies talking about applying a negative gain setting. This is all good info. Do you know a web site, perhaps with diagrams, that explains this further?

I understand that the sensor output is technically linear to start with, and a log transform is applied to get it to what the eye perceives as linear, so then it seems a little counterintuitive to apply a new gamma to put it back into a SLOG profile... get what I mean? It seems like you could have left the data in a 10bit linear profile that still spans the full dynamic range. I expect the explanation is because of better noise performance at the top end? Anyway, in my hunt for answers I usually turn up web sites that are either over simplified, or go into more science than I need to know.
