    Profile for Canon G10 to simulate Olympus E-3 colors

    mronen

      I want to create a profile for Canon G10 which will simulate Olympus E-3 colors.

      I performed the following steps, but the result is very disappointing:

       

      1. Photographed a GretacgMacbeth ColorChecker with a G10 and a E-3, in the same light conditions (Open shade) in RAW.
      2. Converted the RAW files to DNG with DNG Converter 5.4, all default settings.
      3. Opened the E-3 DNG file in Profile Editor. White balanced by right-click on patch #19. Set Base Profile to E-3 Adobe Standard, Color table 6500K, 'Both color tables'.
      4. Set 18 Control Points, one on each color patch, #1 to #18. Wrote down the HSL values for each.
      5. Closed the E-3 file and cleared everything.
      6. Opened the G10 DNG file in Profile Editor. White balanced by right-click on patch #19. Set Base Profile to G10 Camera Standard, Color table 6500K, 'Both color tables'.
      4. Set 18 Control Points, one on each color patch, #1 to #18. Wrote down the HSL values for each.
      7. Noted the numeric difference between the HSL values for each patch in the G10 file, vs the E-3 file.
      8. Corrected the HSL values for each control point, by the numeric difference between the two files.
      9. Saved and exported with a new name.

       

      Obviously I did something wrong, because the result is BAD!

      I'll appreciate it if someone could help and point me in the right direction.

       

      Thanks,

          I'd like to add two observations about my above experiment:

           

          1. If I change the values of a Control Point using the sliders or the point on the color wheel, the preview changes, but much less than the change of the slider. Say, I change the H slider to -10, the change in the preview is only -2, or so. Is that how it should be?

           

          2. If I hover with the cursor over a color patch in the ColorChecker preview the values change, probably due to noise, and it's difficult to decide which is the correct point. I didn't find an option, like in Photoshop, to set the sampling size so the value is an average of several pixels in all directions.
