cameraLogToLinear - Why does not use LogSideBreak?

It would be convenient if we could specify logSideBreak in the Log Parameter,

so why isn’t that option available?

I thought it would be more user-friendly if both logSideBreak and logSideBreak were provided.

There is a simple equation to convert the linSideBreak to the logSideBreak. Please see the documentation here:

It would not make sense to allow the format to contain both simultaneously since that would be specifying two different values for the same point – it would be unclear which to use if they differ. Perhaps a future version of the spec could allow either one or the other to be specified, but these numbers are not user-facing, so it’s not clear how much benefit that would bring.

Thank you for replying

I just thought, it would be convenient for user if I could write it using logSideBreak instead of having to convert it to linSideBreak.

It meant that it would be nice if users could freely choose variables.

Of course, if both are written in CLF, it would make the compile more complex, so I think it should be treated as an compile error.
