- ajross 17y agoHe mounted the lens so that its focal plane was on the scanner element, and sealed the thing to keep light out. That's pretty much it. It's a clever hack, notwithstanding the 4-5 second "exposure" time. This kind of setup would actually be useful in practice for things like rare book scanning, where you can't flatten the pages for fear of damaging the object.

- ComputerGuru 17y agoBut how does that accomplish a 130 MP? What's special about a scanner vs a camera that lets it do that?
- TJensen 17y agoSize. Scanner is 8"x10" or so. The actual DPI of the scanner is lower than a traditional camera CCD, but there is so much more space. Your exposure time is how long it takes the scanner to traverse a "page". Focusing seems painful.
