Would it be possible to enhance the user interface of the Gamma Adjust transformation such that Adjusting an inverse Gamma could be selected numerically on the slider. For example 2.20 inverse Gamma.


Background: Another user, Den, suggested a workflow for processing linear DNG files, including an Inverse 2.20 gamma brightening curve.

Would simply choosing say 0.45 (the inverse exponent or 1/2.22 = 0.45) on the slider do what you need?

It would be convenient to display the inverse ratio of the slider setting , e.g. 0.4545 = 1/2.2 ;
A data entry box would be convenient for entering as formula such as "1/2.2"
