    DNG Profile Editor, Tone Curve – question

    Peter DL Level 1

       

      How to get rid of the 'shadow bump' with the Camera Raw Default Tone Curve ?

      When creating custom profiles with the DNG Profile Editor (chart wizard), I’m usually selecting "Camera Raw Default" or "Linear" as the base tone curve in the Tone Curve tab.

      Profiles with a 'linear tone curve' may at times be useful (or not; which is not the point here), however, the initial rendering in Camera Raw at Camera Raw Defaults (as shipped, except the different profile) is quite dark and dull. Whereas profiles with the Camera Raw Default Tone Curve are too contrasty for my taste, again referring to the initial rendering in Camera Raw at Camera Raw defaults (as shipped, except the different profile).

      From what I understand, the Camera Raw Default Tone Curve includes 3 elements which in terms of PV2010 language are equivalent to: Brightness 50, Contrast 25 and Point Curve: Medium Contrast. PV2013 indicates it all as zero/linear, however, that’s just a matter of terminology.

      I’d like to get rid of the Point Curve Medium Contrast part, right in the profile, by eliminating it from the Camera Raw Default Tone Curve in the DNG Profile Editor.

      Appreciate your advice how to accomplish this.

          ... figured it out on my own.

          File closed.

            Sorry for tardy.

             

            Here's how I do it - put this in a dcpr file:

                please ignore the term "&amp;amp". Not sure what my iPad did here.
