Recently, my Lightroom / NLP has shown errors after re-opening images that I already had converted. In the example below, I wanted to crop images I already had converted and edited a few days ago. While the image is still in preview, everything looks fine, but once the image get loaded there seems to be an error, as it somehow “resets” or reads the conversion wrong and everything turns very bright and orange. Changing the NLP Settings and Profiles doesn’t do anything, and I have to redo every image that I want to crop.
I recently updated my NLP from 3.0 > 3.1 and updated my Lightroom to the latest version.
The first image I took while the image was still in preview/cache, the second one is after it fully “loaded”.
Don’t fret! This just means that your previous conversions were done while you were missing the proper camera profiles. When the camera profile is missing, it will still convert, but Lightroom will use it’s own default “Adobe Color” or "Adobe Standard) as the working profile. When v3.1 correctly loaded the camera profile you need, Lightroom updates the image, and now there is a mismatch between the profile applied and the profile used during conversion.
There are two ways you can fix this:
The easiest way is to manually change the camera profile of any affected photos to “Adobe Color” or “Adobe Standard”. When you do this, you will see the image return to the way it looked previously. You can then sync that profile over to all the other images you need (you don’t need to do it individually).
The other thing you can do is to re-covert the image (this time it will do it with the proper profile for your camera). To do this, you can 1) make a virtual copy (if you don’t want to lose your previous edit), 2) Open the image in Negative Lab Pro, go to the “convert” tab and select “reset image”, 3) Then reconvert and re-edit your photo.
