| 1. | The measurement is taken from the film plane to the subject.
|
| 2. | It was inspired by the film Planes, Trains and Automobiles starring Steve Martin.
|
| 3. | M39 LTM mount with flange to film plane distance 28.8 mm not applicable.
|
| 4. | Both the lens and the film planes are separate and can be moved independently.
|
| 5. | The bellows provides a flexible, dark extension between the film plane and the lens.
|
| 6. | Photographing from the ground, perspective can be eliminated by keeping the film plane parallel to the building.
|
| 7. | Using a focal-plane shutter, exposing the whole film plane can take much longer than the exposure time.
|
| 8. | Due to Petzval field curvature, the film plane upon which a lens focuses may not be a literal plane.
|
| 9. | The cameras were coupled rangefinders, but had a unique focusing mechanism that moved the film plane instead of the lens.
|
| 10. | Due to the mechanical compression the elastomer film contracts in the thickness direction and expands in the film plane directions.
