Do DNG photos possess a color profile or, since this is still sensor data in a wrapper (from NEF-raw in my case), do we say there _is no_ inherent color profile? I had not been paying attention, but when (at last) I looked at my DNGs in Adobe Bridge, I was surprised to see "Color Profile: untagged."
Somewhere I read that LR operates in ProPhoto RGB working space, altho the full implications of this are over my head. Therefore, if my monitor is correctly calibrated, is what I see "as if" the data were ProPhoto RGB? (My monitor has a far more constrained gamut, I know, and interprets the picture data that it is given to display.)
Meanwhile, I see that when I export (or send to be edited in PhotoShop), then color profiles kick in -- for my exported 16-bit TIFFs I use Adobe 1998, and for my JPEGs I use sRGB, since they head for the Web.
Here's my puzzle: if I pass along the DNGs, how are they interpreted? I thought that when someone opens my images in a "smart" application with a calibrated monitor, that the app would read the color-profile tag and present the image accordingly. (As for the Adobe 1998 TIFFs.) But what happens when a non-Adobe app opens one of my DNGs? If it is a "smart" app, does it assume-by-default that the data (including the embedded XMP parametric adjustments) are "as if" ProPhoto RGB. Yikes!
This query must have been discussed often, but my search on this forum failed to turn up the topic.
