Description

There was a lot of improvements in the auto-tuner of "filmic", that would be relevant for "unbreak input profile" too. For example "unbreak input profile" often sets the black cursor to -16 EV while this was changed for filmic. Also, unbreak input profile has a "dynamic range" cursor while filmic has a white relative exposure cursor for the same purpose (modulo an addition/subtraction with the white cursor).

Not a very serious issue since this log mode in unbreak input profile is much less useful since filmic is there, but it would be cool to be more consistent.

History

#1 Updated by Aurélien PIERRE 9 months ago

The dynamic range option vs black/white exposure is still something I'm not sure. Filmic needs the white and black because these values are used later in the S curve building. Unbreak profile does nothing with it later. The dynamic range is a well-known, tabulated, value you can find out for each sensor at a given ISO sensibility, and I feel it's more intuitive to use rather than asking users to compute the black exposure from the DR and the white exposure.
