Profile Edition/MakeinpuICC Question

Submitted by dje on

Forums: 

I have the process running to produce ICC camera profiles using a SpyderChecker24. One thing I notice in the SpyderChecker reference data file is that the illuminant is D65. However my test shot of the patches has been taken under approximately D55 illuminant. Should I be chromatically adapting the XYZ data in the SpyderChecker24.cie reference data file before runing MakeinputICC ?

Thanks Dave

You can try chromatic

You can try chromatic adaptation, however that's not what I would be doing. I would measure the chart to get spectral reference.

Thanks but I don't think I

Thanks but I don't think I have a suitable instrument to measure the spectral reference of the patches.

There are rental services, you can try https://www.lensrentals.com/rent/x-rite-i1studio-spectrophotometer

Generic references are usually not very accurate.

Alternatively, you can feed CGATS from RawDigger into basICColor Input (they have spectral reference for SpyderCHECKR and a free fully functional 14-day trial), as it is shown on this video: https://www.dropbox.com/s/9xp9ze26i1gmhon/input%205%20profile%20from%20R...
