As someone who has built multiple custom macro film scanner setups, owns basically very consumer film scanner of note (including the Coolscan 9000 and the Minolta Scan Multi Pro), and is intimately familiar with the workings of various film scanners and science of digitizing film, I don't think this article provides particularly good advice.

Just for instance, the LS-2000 features in the post has an advertised optical resolution of 2700DPI, which means the absolute maximum megapixel resolution you can get out of that thing is a little over 10MP. Film scanners are notorious for overstating their optical resolution, which has nothing to do with the resolution of sensor used to digitize the image data and everything to do with the lens in the scanner. You can have a 200MP sensor scanning your film but if your lens can only resolve 1000DPI you will have a very high resolution image of a low resolution lens projection. It's maybe a little better than a flatbed and it features dust removal, but in the year of our lord 2024 the LS-2000 is not a good choice for scanning film.

As for his macro scanning setup, he appears to be using the digitaliza for film holding, which is a notoriously bad product with many known flaws. Negative supply makes a line of lower cost version of their very good film holders, and Valoi also offers an affordable system of components that I highly recommend. There is a ton of good information out there about macro scanning, and had the OP sought it out he could avoided his little adventure in retro computing.

Also, the LS-2000 is a noisy POS. I owned this thing for years (bought new) and put plenty of time into it. It just sucks. It was only mediocre for slides and black-&-white negatives; for color negatives it was nearly useless. You could never remove the base negative color and retain good image color. The dynamic range sucked.

I sold it on eBay years ago, then researched what might be better. The general opinion was that consumer-accessible scanning peaked with the Minolta Dimage Elite 5400 II. Of course these were long out of manufacture, but I managed to find one new in the box on a small auction site. To this day I haven't gotten around to scanning a single piece of film with it. Maybe this post will finally get me off my ass...

B&Ws also scan poorly on it if the negatives are even a little bit dense. Tricky negatives that could still produce good images in the darkroom had no hope on the LS-2000.

Yeah, it's another one of those products that inexplicably collected cachet and reputation but was trash in reality.

I had a VCR of similar reputation, which also suffered from a noise-filled image coincidentally (the Panasonic AG-1960).
