I’ve never had this issue before with NLP. I received negative files from my lab today and when I convert them (no matter what I do) they appear almost IR. Yet I called the lab and they rescanned them and converted them with their scanner and everything looks great. Curious if anyone has ever seen anything like this before with NLP. First image is my NLP conversion and the second image is the image that the lab converted. Thanks for your help in advance.

Such differences are hard to diagnose without the original scan.

How did you scan them?
This looks to me like you might have clipped a color channel during scanning. You might retry a scan making sure your histogram is in the middle and no color channels are clipped.

The scans are lab scans. Attached histogram screen shot of the photo that isn’t converting correctly. The lab calls this process of delivering negatives “scan to positive”. I’ve had the same lab do this for me a couple times and they’ve never given me scans that are “over-scanned” off the negative so that I can white balance like all the tutorials online. However, this is the first time I’ve had an issue not having an area outside the negative to white balance to. Should I be giving them special instruction to send me scans that are off the negative enough so I can perform this white balance? Is it fair to assume they are scanning with their scanner and then cropping that outside information out and then sending to me?
I’m limited to one photo per post so continuation here:
Below is a photo attached that I had no issue converting from another roll. This roll was a daylight balanced stock and the one of the pool above is a Tungsten balanced stock. Would that have anything to do with the issue I’m having?
The original scanned image is in a JPEG file of 1920 pixel on its long side? That is what I get when I download the sample. If this is the case, check the scanning part in the User Guide.
I’m just noticing this now that the other rolls I’ve converted to negatives and then used NLP with this lab has provided me with TIFF files and that as you pointed out this entire last roll are jpegs. Does NLP glitch or not like jpegs?
I’ve noticed that the colors in the photographs taken at night on this roll are far better than the photos with any sort of daylight in them. The ones shot during the day or at dusk look very off.
Another thing is the lab is using a Noritsu scanner and is saying that they can’t scan beyond the perfs and outside the image on 35mm, they can only do that with their scanner on medium format. Is this correct for the Noritsu?
Here is a google drive link to the three photos as negatives that I posted above. Curious if ya’ll might try converting them on your own and seeing if the results are the same as mine.
Thanks so much for your time in trying to help with this issue; it’s been keeping me up.

@KylePahlow JPEG source files? I’d not even try, JPEG is simply too restricted to provide good conversions. Please use RAW for your camera scans. 16 bit TIFF is okay too, but anything else tends to waste one’s time.
