Interesting project! I scan 35mm and medium-format film with a mirrorless camera, macro lens, and Lomography film holder, then convert with Negative Lab Pro in Lightroom. I’m happy with the results, but the Lightroom subscription has me considering writing my own converter.
Could you share more about your NumPy pipeline, or publish the code? I’m particularly curious about how you use the blank film reference and roll-level measurements to handle the orange mask, color balance, and tone curves. Do you use camera/scanner calibration profiles or film-stock-specific adjustments, or estimate everything from the scans themselves?
Also, your screenshot appears to show an OpticFilm 7400. Would you recommend it, and roughly what did you pay? Have you tried camera scanning? I’ve been considering automating film advance and capture on my setup, but consistent color conversion is the part I’m least confident about.
Can you please not post AI-generated or AI-edited comments to HN?

Of course, it's impossible to know for sure what was LLM processed or not, but some of your posts (like this one) have been getting classified that way.
It is a very sensible and reasonable comment- literally all questions I'd want to ask to replicate the setup, in a format that's easy to parse. If the author did use LLM it did not substantially alter the content of their question.
I thought it was a reasonable comment and, like you, I thought they were good questions. I haven't followed what kind of watermarking LLMs are putting in their output that might be a telltale for their use so maybe it's readily apparent in a way that isn't to me.
I'd be mortified if a comment I made was accused of being LLM-edited or "created". I don't use any of that junk but if I'm reading LLM output and not realizing it I just might be adopting some of its mannerisms and styles with realizing it. That's chilling.
I ended up discussing it with the moderators and they interpret "transcribe and formatting" as contributing enough that they want to "educate" the user to not do that.
In my mind, using an LLM to lightly format a legitimate questions falls below any threshold I'd apply to AI-written writing. I often dictate HN messages to my phone, and in my case, personally edit the message (tediously), but if there was a tool that produced text that looked lightly LLM, I wouldn't care about it at all.
It's not a big deal because in five years, the idea of chiding a user for using an LLM to enhance their text is going to be considered ridiculous. I've lived through enough computer revolutions to know this; once, I didn't get a job (in ~1989) because I could type 80wpm but made a bunch of errors... on a typewriter! The agency told me they needed people who could type 80wpm on a typewriter.
