Seems like only yesterday... I've not followed this thread closely, and don't know if you guys are discussing Photometric 8 or 9, and what bitdepth. To be on the safe side, I thought it best to add a link to the specification supplements. http://partners.adobe.com/public/developer/en/tiff/TIFFPM6.pdf This supplement was largely unknown when we did the work concluded in http://www.asmail.be/msg0055212264.html. Also, neither the original specification, nor this supplement, described the 16bit per channel encoding we investigated. http://partners.adobe.com/public/developer/en/tiff/TIFFphotoshop.pdf This supplement was written after our work on 16bit per channel Lab in TIFF. It does mention the 16bit per channel issue. I don't know if it contradicts or confirms the conclusion Marti and I arrived to in 2001, as I haven't investigated, and don't remember too much detail. Unless Marti feels otherwise, my humble opinion is that, should there be any contradictions between our findings in 2001 and any of the specification supplements, the specification supplements take precedence. With the original specification, the two supplements, and our work in 2001, it seems there's a lot of different stuff people have to investigate to come at a total insight on L*a*b* in TIFF. If anyone here is willing to help, I'll gladly try and make a good overview and add that to the TIFF documentation over at http://www.awaresystems.be/imaging/tiff.html. Please let me know.
