I am trying to figure out some low-level temporal characteristics of film exposure.
In particular, I am looking for detailed information what exactly happens when a film frame is exposed:
- When/how is the frame being transported behind the lens at what point in time?
- When/how is the shutter being opened in what period of time over which part of the frame?
- At what point in time is the shutter being closed, and how?
- How is the shutter constructed mechanically, and what triggers it?
I would like to understand those details in order to relate analog film camera technology to digital film with global and rolling shutter.
Attached is a synthetic exposure-time diagram for a simulated rotary disc shutter similar to http://en.wikipedia....ry_disc_shutter (but with the shutter positioned below the (landscape) frame). I would like to understand whether that is an accurate representation of what really is happening?
In addition to the recording side, I would like the same information for the projection side (double flashing etc.).
Any advice or pointer to existing information or books would be most welcome,
thank you very much
