Corrected 2026-10-23 - see C3-B680-04; the original statements below are kept for history and are superseded where the correction says so. Lutz states a projection convention of 16 pictures per foot of film and 1 foot per second, so 16 frames per second, and says the animator must keep this in mind. His worked example photographs each drawing on two frames and holds the opening drawing for 2-3 feet (2-3 s). He treats holds, "dramatic pauses" and reading time for dialogue cards as ways to get footage from few drawings. These are 1920 US conventions from one book, not a general timing rule.

Curator correction 2026-10-23 (discovery audit record C3-B680-04; sources re-fetched 2026-10-23, excerpts re-located by curator GET): Problem. C3-B229-G70-01 says Lutz photographs each drawing on two frames (supported: 'two turns of the handle ... two sections of the film'). Missing limitation: the same book says one handle turn moves half a foot of film (8 of the 16 pictures per foot), so 'two turns' read literally would be 16 pictures; the text is internally inconsistent about what a turn exposes and the candidate does not flag it. Method. Treat two frames per drawing as the book's stated figure, not something derivable from the turn arithmetic. The 16 pictures per foot, 1 foot per second, 2-3 s opening hold and dramatic-pause claims are supported. Limitations. 1920 US convention from one book. Version. Gutenberg ebook 73455.

Curator qualifications: Lutz assumes 16 pictures per second, shoots drawings on twos in his example and treats holds and reading time as planned durations.
