Scanning a 300-page book in one sitting

Most of the time lost in scanning a book is not the shutter — it is picking the phone up, framing the page, tapping, and putting it down again, three hundred times. Set the phone up once, pointing straight down at the open book with the whole spread in frame, and do not touch it again until the last page.

Anything that holds the phone steady works: a stand, a stack of books with the phone on top, or a shelf edge. What matters is that the distance to the page does not change, because vFlat measures the page shape from that one viewpoint.

With auto-capture on, vFlat watches the frame and takes the picture when the page is flat and still. You turn the page, hold it down, and wait for the shutter sound. There is no tap, so there is nothing to nudge the phone out of position.

Your fingertips can stay on the page. They are removed from the scan, so hold the paper wherever it is comfortable rather than pinching the very edge.

Frame the whole spread rather than one page at a time. vFlat splits the spread down the gutter into two separate pages, already in reading order, and flattens each one on its own. A 300-page book is 150 captures, not 300.

Turn, hold, listen for the shutter, turn again. Once the rhythm settles, a capture every four to five seconds is comfortable, and 150 captures pass in about fifteen minutes. If a page comes out wrong — a shadow from your arm, a page not quite down — retake it there and then rather than hunting for it later.

When the last page is done, export the whole book as a single PDF. Run text recognition on it and the book becomes searchable — every chapter, every footnote — from the phone it was scanned on.
