Thank you for your help.
I just scanned the negative as positive TIFF, then right clicked on the file in Windows Explorer to open it in Lightroom Classic. My Lightroom is using standard settings, so i did not see a dialog of edit/copy questions.
I just imported the image, whitebalanced and crop it. Then converted it with NLP 2.2 and pressed OK to see the results. Then i closed Lightroom and it asked me to backup the catalog. Afterwards i had been copying the files to another directory and lost the history when opening Lightroom again.
So i am not sure my TIF .are still original, but when i look at the file properties of the image in Windows Explorer, i see the creation datetime and modification datetime of the file is the same…so can i conclude that it is still the original positive scan?
When i apply white balance to this file again i do see the border color changing again… so i am not sure, else i have to rescan this serie again.
I find Lightroom rather slow, so i only use it for NLP 2.2 conversion and then use Photoshop.
