[Lcms-user] General question about CIE Lab and TIFF

[Aaron B. <bo...@gm...>]

Hello!

This isn't directly related to lcms, but can anyone "illuminate" me
on the two CIE tags PHOTOMETRIC_ICCLAB and PHOTOMETRIC_CIELAB
in the TIFF format ?  I can't find much on the web about them.

I am trying to relate them to the two CIE colour spaces supported by JPEG
2000
standard:
1) CIE with default D50 illuminant
2) CIE with custom illuminant, which I plan on storing in the TIFF ICC
profile.

Thanks very much,
Aaron
