Hi,
There is a significant interest in the Color Checker Passport software and the DNG profile editor for camera calibration. In a sense it's overblown in my view.
Here is what I see:
- Doing camera calibration for some specific conditions is a good thing. Takes care of possible individual variations between cameras.
- Would we shoot repro, it may be a good thing to build a calibration for a specific light source.
On the other hand:
- After doing some basic profiles, like studio strobes, 6500 K sunlight and incandescent we don't need much more than a white balance patch.
- Lightroom doesn't have a hierarchy of DNG-profiles so it's not feasible to have a great number of profiles for different light situations.
I made some tests with different light sources, flash, incandescent and energy saving lamps in the same configuration. I failed to see a large advantage of calibrating for each sort of light versus just using WB on a grey patch.
Finally, the Color Checker Passport software is a free download. If you already have a decent/recent CC-card you should absolutely check. The Adobe DNG Profile Editor is more flexible, that tool is also free.
Best regards
Erik
