Sorry, I have no idea what you said.
I am looking for a solution to shoot standard a ColorCheckr chart and adjust colour.
Basically profile the camera like Lightroom does, but without using Lightroom.
Hi Bob,
I think basically Phase One doesn't believe that a 24 patch color checker is enough to build a good profile, and I somewhat agree (also depends on what one calls 'good'). That's why those involved in creating good camera profiles often use a better target, a 140 color patch
Digital ColorChecker SG, that covers a larger gamut and many more intermediate colors (an "Array of 140 colors: 24 patches from original ColorChecker, 17 step gray scale and 14 unique skin tone colors"). Some use even more elaborate equipment and procedures. Even shooting the target is not as simple as people tend to think, and the results are therefore often disappointing, from a viewpoint of striving for perfection.
What you can do, is take an existing CaptureOne profile for your (or another) camera and tweak the color response with Capture One's color editor tool if you think it is not correct or to your liking, and save that adjusted response as a new profile.That approach actually makes a lot of sense, and is very flexible. Warning, if you base those corrections on a simple 24 patch ColorChecker, you will get strange colors elsewhere, also depending on the variations in illumination. Camera profiling is not easy.
What you can alternatively try is to create your own profile e.g. with the tools in the
Agyll CMS, but you need a spectrometer to do it, or use a
GUI front end which also has some averages to support 24 patch Color Checkers that have not been accurately calibrated/measured.
RawDigger also has
functionality to save CGATS data for profiling software.
Cheers,
Bart
