Log, Lin, 10-bit, 12-bit, etc

[SimonBjork]

To confuse things even more, I've got another question of the use of Redlog.

In VFX, I work with linear EXRs or linear TIFFs out of RedcineX or other application. When compositing I sometimes push the values above 1.0. That's okay if my final output is to a "normal" dpx log file, all the overbrights are preserved. If I apply a Lin2Redlog in the end of my composition, a lot of values stay above 1.0 if they were really bright. So my question is, can I use normal log curves instead of the redlog one? Cons?

Gramme,

Looking for clarification, are the log curves in RCX like REDLog based on a linear starting point like the forthcoming REDFilm curve, or is that an equation specific to REDFilm?

Thanks.

All our curve math is based on a linear-light starting point.
