| I was part of a font consulting company during the Postscript /
| Truetype font wars, and we reconstructed fonts from scans or
| earlier digital formats. Most of the work was fixing bad data.

| Cool to see this reposted! I see on the forums are using
| dedicated compact cameras. Are they still better than
| smartphones?
|
| I also wonder if using the LIDAR from iPhones for example could
| significantly improve the flattening process.

| I made one of these during my MBA. I spent close to $2000AUD
| including the two Nikon mirrorless cameras I purchased. I am not
| particularly handy and made it out of spare 2x4 lumber I had so
| it wasn't light.
|
| But it worked, I scanned about two dozen short term library books
| that I needed to reference frequently during my course at a cost
| of about $85 per book. If I'd purchased the time limited ebooks
| they would have cost $125 each, and been scattered across 3
| different bookstore apps.
|
| I would scan while watching tv and could do approx 1000 pages per
| hour.
|
| I also learned that I should not do carpentry and potentially
| saved tens of thousands by hiring a handyman or carpenter for
| home diy...
