The files aren’t really untagged, they are tagged with a profile named “ Phase One no colour correction” which, when stripped off in Photoshop with sRGB as a default RGB space produced no colour change. For me this meant that the files has been converted (encoded) into sRGB because the data was obviously in sRGB numbers and not Nikon D-70 numbers. What else could possibly explain how the file aquired sRGB numbers?
As I stated, the "No Color Correction" tag follows the processed. When you strip it off i will agree that it looks similar to srgb, but its not srgb. This new Profile C1 calls "NCC" is the closest choice to not getting data that has been messed with. As for your nikon experiences, that is consistent with our findings with regards to what gets tagged to the file versus actually applied to it. Should you wish I would be happy to continue this offlist.
