This needs some updating.

There are a total of 167 "folders", plus various meta-folders.

Camera process: Canon PoweShot G10, manual focus (have to disable safety autofocus,
etc. and save it in the C1 profile where we work), should focus around 0.7 meters
(scale is logarithmic, so good luck), F/3.2, ISO 200 (must use dial), shutter 1/60 sec.
We focus towards the bottom center of page, not center of page, using the dial and
autofocus button until we are hopeful.

- mention the manual focus process we changed to later

- mention the early flatbed scanner (PNG) work
