I think we’re heading in the right direction.
I’m just a little confused, because the problematic photos do have the ‘Negative Lab’ profile assignment, but there is also a ‘’!’ Profile missing’ warning.
When browsing for profiles (grid view), I see that the NLP profiles are there (v1.0 and 2.0), but the exposures are way off for either. Selecting ‘Embedded’ profile seems to fix the exposure issue, and allows me to edit the photo in NLP as I normally would.
Oddly, the same profiles don’t cause the exposure issue for photos that were converted with NLP, and I can chose either profile, with no noticeable change in exposure.
edit: alternatively, for some black & white photos, the issue can be fixed by selecting ‘Color,’ for Treatment, under Saved Presets, in Library Mode. Other photos become blue, if this method is selected. For Color photos, since the Color mode is already selected, the only way to fix it is to set the profile to Embedded, under Develop mode.
