    Imitating Camera Raw Calibration settings with Adjustment layers

    EeroKau Community Member

      Hi,

       

      I do quite a lot color grading and color manipulation with Lightroom, Photoshop and Speedgrade.

      Sometimes I like to use Camera Raw "Camera calibration" Settings to play with hues of the image.

       

      I have yet to found a way to imitate or reproduce the look with  Adjustment layers inside Photoshop.

      I have tried with channel mixers and hue/saturation adjustment layers with no good results.

       

      I want to use Adjustment Layers because then I can export the look as Lookup table for other applications.

       

      Do you have any hints how i could achieve these kind of effects as in the sample image below?

      Cheers,

      Otso

          This mode in Camera Raw / Camera Calibration adjusts the three primaries of the camera sensor.

          This is equivalent to an adjustment of the chromaticity coordinates of the working space primaries.

          These are not directly accessible in an image processing workflow. One had to modify the ICC profile

          of the working space.

          The purpose of this hue modification in ACR is (in my humble opinion) a weak correction of the camera

          sensor primaries, perhaps because of ag(e)ing (though I never heard of).

           

          This is the effect, but with unknown scale factor:

          (neg) shift toward-----Original------(pos) shift toward

          magenta-----------------red-------------yellow

          yellow--------------------green----------cyan

          cyan----------------------blue------------magenta     

           

          IMO, one cannot mimic this effect.

            Thank you for your response. That explanation clarified the the mechanisms behind the tool.

             

            However, I still find it odd, if I would be unable to imitate that look inside Photoshop.
