Some modern 35mm emulsions can record ~500 megapixels worth of detail, but good luck getting all that detail in a digital scan.

The scan is the least of the problems - good luck getting to that level of detail with mostly vintage lenses, balancing depth of field and diffraction, keeping the film perfectly flat, on a stable enough tripod with no vibration whatsoever; developing perfectly in the dedicated developer. Yes, it's impressive but no, it's not relevant to the average user or hobbyist.

I wonder how this compares to Technical Pan, which I imagine it was modeled after.

500 megapixels can have less detail than an old 1 mpix digital from 2001.

[Image resolution is a very complicated topic](https://en.wikipedia.org/wiki/Image_resolution) and megapixel count, or even lines/mm does not tell the full story.

All the current Nikon Z bodies (and probably other brands too) have different levels of pixel shift where it’ll take 4 or 8 images and basically cancel out that it’s a bayer sensor. The bayer array is a 4 pixel pattern, so it moves one pixel to the right then one down and then one back to capture all 3 channels for each individual pixel. For things like film scanning it works flawlessly, I use it all the time.

Then it’ll do a 16 or 32 shot stack in order to do the same thing but with more resolution.

It’s been a feature of Olympus (now OM System) high-end cameras for years. I did not realize that Nikon had picked it up as well.
