Light first
Turn off the flash, look for the window, avoid your own hand’s shadow. An under-exposed but even page reads better than a bright one crossed by a shadow.
Flat, straight on
The reading direction doesn’t matter — the tool straightens it — but a page photographed at an angle loses its margins. Hold the camera directly above, not at a slant.
The whole page, margins included
Folios, stamps and shelfmarks sit in the margins. Frame wide: the tool finds the text, it doesn’t recover what’s out of shot.
A double-page spread, one shot
An open book is photographed in a single shot, and read as one page. That’s half the photos, and a single page to count.
Don’t rename anything
The order the shots were taken in is the order of the box; the name the camera gives keeps it. One folder per shelfmark or per day is enough — the tool goes through subfolders.
Don’t retouch anything
No cropping, no rotating in an editor: every save recompresses the JPEG and slightly damages the text. Deposit the original as it is, the tool takes care of the rest and keeps it intact.
