Thank you. You always have good questions and comments. Here is what I can tell you so far. I agree with you that it probably is not the cards as it’s well downstream.
1, If the issue is the LR export, instead bring the stack into PS and do a File-Save-As and use the same target output parameters and see if the image issue repeats.
I will try this using both PS and Bridge to see if it persists.
2, You gave a lot of details, but you didn't attach the example images, nor provide the specs on the LR export. What are those export parameters, and if you change them, does that impact how the example input stack exports?
Export is to only convert from NEF to TIFF
3, Is there anything common in the problem stacks? Do they have more images, say above a certain threshold count? Are the files on disk above a certain threshold in bytes, GB, as compared to a stack with no problem?
Stacks consists of between 50 and 300 images. Typical uncompressed raw size from FF Z9 8256 x 5504. Not all images are affected. I will have to do a new export to see if it’s the same ones or random.
4, If you start the process over for one specific stack, from the NEF import forward, does the issue repeat for that stack?
Will have to check
5, If you export one stack that exhibits this issue, if you exit LR, restart LR, and re-export the same image, does the same problem occur?
Will have to check
6, If you export one stack that exhibits this issue, if you exit LR, restart the computer, and return to LR and re-export the same image, does the same problem occur?
Will no 5 first to see, then will check this.
I think that I will try PS and Bridge first to see if this occurs, then try other steps.
Many thanks
