Scanning with a digital camera

How do you get NLP to scan the sprockets, especially the colourful C200 data surrounding and above the sprocket? The NLP user guide points to excluding extraneous negative, such as the rebate as it can throw the colour conversion, and exposure levels amongst other things.

Was reading thru this thread and thought I'd show you all what I came up with. My first attempts were a little difficult with my tripod set up that I started with way back in '17(?). Thanks to all of you here for the inspiration to get this rig. All of it is used stuff from various places except for the adapter on the camera.

The image above shows area outside the film space. The film image is the full image uncropped. I found that I get better results quicker if I crop off all the bits that are not the image, but I still get good results if I include the boundary. I just need to apply more correction once it is downloaded into LightRoom.

For the images that I show with sprockets? I use a Lomo Digitliza film holder.
 
... recommendations for currently available light sources that are known to give even light to at the very least medium format.

I have the Beseler Dual-Mode Slide Duplicator and it works great except for uneven light. ...

I've tried my old iPad Mini, but it is not even. I think I tried my iPhone 11 with similar issues.

I've tried a lot of things. Some suggestions:
- Video lights are far brighter than light panels or phones.
- Electronic flash eliminates vibration issues, but is difficult to rig.

My answer: Flash or Video light, then two layers of diffusion. I use matte drafting mylar (brand Dura-Lar). Experiment with spacing. Mine at moment: flash - one diffuser - 2" - another diffuser - 1" - negative.

Hint: bamboo drawer organizers or pre-made boxes at craft store are helpful for rigging the diffusers and spacing.
 
I've been playing around with the beta for the next NLP update. Rescanned some film I previously had done at a lab and tried out the Pakon LUT that'll be released for NLP soon. Not bad! I've never used a Pakon before so I can't speak for how close it is, but I liked how they came out.

Thanks kindly, Huss 👍 (Sorry for not replying earlier, the reason being the page in view moves so fast on RFF although I did book-Mark this thread but took my eye off as it were. )
I’ve got one of those Digitliza meg holders, so good to go with that.

This is similar to what I use, except the bellows is mounted on a focusing rail and the rig is mounted on a macro stand.
 
Looking for thoughts and expertise on this question: What's limiting image qual in Cam-Scans?

For a "typical" user, 35mm films and a 24MPx body. What's limiting?
- Image detail on the film?
- Copy lens?
- 24MPx Bayer sensor?
- Software (e.g. negative inversion)?

Would that change with a 50MPx body?

And, for any of this, how would we know? What comparisons would give us some answers?

Why? Inquiring minds want to know! Regards to all! Stay safe.
