Film Image Format
From Photo-3d
This appendix gives the placement on film of several 3D formats. These appear actual size in the original print of this FAQ. The same length of film is shown in all cases for comparison purposes, even though this does not always allow an even number of frames to be shown (i.e. the Realist and European formats)
Standard 35mm film dimensions
For complete information, refer to ANSI standard PH1.14-1990.

Nimslo / Nishika (4 lenses) - 4 sprocket (24 x 18)
Film chip size is nominally 18 mm with a 1 mm frame separation.
34.95 +/- 0.05mm
4.75 +/- 0.03 mm 1.98 +/- 0.03mm
2.80 +/- 0.03mm
2.00 +/- 0.15mm

Image Tech 3d Magic and 3d Wizard (3 lenses) - 4 sprocket (28 x 18)
Image Tech Professional (5 lenses) - ???
Realist - 5 sprocket (24 x 23)
Film chip size is nominally 23 mm wide with a 0.75 mm frame separation In this format, the film advances two frames for each exposure. This results in an unused exposure at the beginning and end of the film. The extended film sequence is 1L-unused-2L-1R-3L-2R-4L-3R- etc.
European - 7 sprocket (24 x 30)
The film chip size is nominally ?? mm, with a ?? mm frame separation. This pattern requires the camera to advance first one frame, then three frames - the extended sequence on film is 1L2L1R2R - 3L4L3R4R - 5L6L5R6R - etc.
