CHROMiX

ColorThink Pro CMM

I wonder what the CMM used by ColorThink Pro 3 is. Perhaps the OS CMM? And how is the absolute colorimetric rendering calculated?

This is because, e.g. Adobe RGB (0 128 0), converted to Lab (with Apple CMM and absolute colorimetric), get similar results in Photoshop, ColorShop, ColorSync Calculator, but a different result in ColorThink Color Worksheet.

Thank you.

I wonder what the CMM used by ColorThink Pro 3 is.

I asked myself that question too.

It probably uses LittleCMS, I got an error mesage today when dragging the Getty test image (has TIFF RGB embedded) into ColorThink Beta 11

Error dialog is titled ‘Little cms’;
Error #3000; Bad tag signature cacacbcb found.
Error #3000; profile is unsuitable for output.
