Re: Laser-cut stand to digitize newspapers

Please post an update once you've completed a scanner and worked through all of the kinks. It's helpful for others that visit the site and are looking to solve the same sort of issues (newspapers/posters/large page sizes). Thanks!

Re: Laser-cut stand to digitize newspapers

Seems overly complicated for what you need to do. You basically need a copy stand with some way to hold the pages flat. In the simplest case, the camera, and even the lights, could be positioned on tripods instead of the complex system you've shown. That being said, overkill doesn't necessarily hurt...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

Rather than build a scanner large enough to handle that one large book, you might consider scanning that one book manually one page at a time with a single camera on something like a crude copy stand and a build your scanner based on the size of the majority of the books you have to scan. The reason...

Re: safe hand removal of plastic binder combs

Since you're only scanning one 100-page book, I'd do it on a flatbed scanner or a copy stand and be done with it. You shouldn't have to remove the spine for this. Since you can open a comb-spined book 360 deg. where it will fold back on itself, you might get away with putting a flat spacer board (I'...

Re: New scanner by Archive.org?

I wonder why Archive.org doesn't want to show TTScribe which is their main scanner now. We can only guess. It may be the scanner that the seasoned page-flipper was more familiar with. That scanner also is more "open" than the TTScribe and makes photographing a person using it somewhat eas...

Re: New scanner by Archive.org?

The scanner used in that video is what the Internet Archive used before they switched to TTScribe. If you look at the page on wikipedia on Book Scanning, there are photos of that scanner there dated from 2011.

Re: Recommendation regarding brightness

you can compensate to some extent this problem by photographing a flat white sheet.. Yep. That's the technique I use to mitigate that problem. The first photo taken by each camera are of blank reference pages. The post-processing software that I developed does this correction automatically in the b...

Re: Recommendation regarding brightness

Probably not that critical if you're going to scanning black text on a white page and then post-processing with something like ScanTailor that binarizes the output. If you're looking for something more accurate than that you could always use an 18% gray card to set things up. I remember reading thro...

@jeffamuffin

If you don't mind, will you post the file size savings of your work so that we can get a rough idea of what one could expect by going this route? Thanks!
