It's a simple exposure simulation derived from mathematics involved
in a chemical reaction. I may add another method derived from
photography.

You are free to use it as you like.

Good for that too to some extent. There is a link between these two but
I'm not trying to do human vision simulation, that would require way
too much work.

assumed_gamma can be abused to give this effect (just add a value to
your current assumed_gamma). I suppose there could also be a treshold
value.

ABX may include it here:
