Hi Forum, not sure if this is quite the right category to post in, so please let me know!
I don’t think this is a bug or an issue with NLP – I’m just curious about the behavior. I scanned a bunch of B&W negatives and inverted them in NLP. The scanned TIFFs are around 28 MB at 3200 dpi. After saving a positive copy of the tiff for further edits, I noticed that the positive copies are nearly 3x the size at ~80MB.
Neither my scanner’s tiffs nor the NLP copies are compressed, so it’s not something on that front.
For a little more context, my workflow is kinda cursed in that I scan the negative, pull it into Lightroom Classic, do the NLP inversion, save the positive tiff in a subfolder, and then pull that subfolder into Lightroom CC for final edits. I usually end up deleting the original scans and keep the inversions on hand. So obviously saving space would be nice and so would eliminating Lightroom CC from the workflow. I know that I can sync Lightroom Classic photos to the CC library, but because the curves and things on the inversions are off the negative, I find it difficult to edit further. And now I’m going off topic!
Anyway, why are the NLP positive copies so much larger than scanned negatives?
