Sometimes, using roll analysis causes some (usually more than one, but not more than 2 or 3) of the photos on the roll to turn blue:

disabling roll anaylsis for those frames solves the issue:

I’m using NLP v3.0.2, the latest at time of writing.

I can provide the CR3 files for this photo or the whole roll, if that would be helpful - but i’d prefer to email them than share them here
