Yes if you save to TIFF...it gets locked in (That's the case with any program). Same if you save to JPEG but has no effect on the original RAW file. In this case you saved the TIFF to aRGB because you applied it.
I understand it never does anything to the original RAW file.
Sorry, I wasn't sure from the original wording. Clear now you have that down
Second reset the default workspace to aRGB and force to open checked. Reopen the same RAW file and simply save as tiff with embed profile checked.
Yep, color profile always gets "baked in" when you save to TIFF. Same with Photoshop and when you convert the TIFF to another profile then thinks get lost. Here you saved to TIFF to sRGB (the original color profile that was in the NEF instruction).
Not when you have "Use this instead of embeded profile" checked. The saved TIFF is aRGB not sRGB. With this unchecked it ignores the default color space setting and goes with what is embeded in the file. The working space and the saved file will be whatever was embeded.
That's were I'm not sure. The Color Profile panel (and adjustment menu) seems to affect what profile is saved in the TIFF/JPEG. The opening preference seems to always affect what color space is saved to the TIFF/JPEG but does the NEF. That's silly if true.
Now open both images in photoshop. When I did this they do not look the same even though they show the same profile embeded. Use the color picker on a specific spot, the colors aren't the same in the two images. But they should be exactly the same if apply profile after the RAW file has been opened in CNX2 does the same thing as forcing a profile application as the RAW is being opened.
Now I see what your doing. It wasn't clear before. I think the forcing open (in the second case above) doesn't actually change the profile saved. It only sets the working space color profile used and when you save the TIFF it saves in the original color profile that was used in the NEF. To change the profile in the TIFF from the one set in the original NEF...you have to use the Color Profile panel and apply it before saving.
At least on my machine this isn't how it works. Please go -test this yourself- exactly as I described before we discuss this any more.
I did it again and it saves the TIFF as aRGB if you use the color profile panel and saves the TIFF with the original embedded sRGB in the second case
Have the "use this instead of embeded" checked in both cases with sRGB working space set for the first, open a RAW file, apply aRGB and save as tiff named "apply.tiff". Close the image. Set in preferences aRGB color space, "use instead of embeded" checked, open the same RAW file and simply save as "open.tiff". They will both be aRGB images now.
Photoshop reports the second as aRGB though, so you're right but ViewNX2 reports it as sRGB. It appears that the tag CNX2 sets is wrong while the actual color profile the file is in is indeed dependent on the Color Profile panel. That's indeed a silly way to do things but is how I understood it....though the tagging is a new quirk/bug to keep in mind
When I open them in photoshop, yes they -both- are aRGB images but don't look the same at all. The one I opened with aRGB looks "normal", the one I applied aRGB to looks blown out and strange.
In my case I get a sRGB Tiff and an aRGB Tiff. I shoot in sRGB and rarely need a different color profile but will be careful when saving to a different one with CNX2.....will be sure to use the color profile panel and be careful not to use the preference opening setting. Thanks for the help.
