Lecture 15: Cameras & Lenses (18)

I'm confused about the naming convention for the 35mm-format film. Why would a sensor size of 36x24 be named 35mm?


The width of the film is 35 mm, but only 24 mm is used for the actual image (since in film cameras, extra space is needed for miscellaneous padding/other things*). This isn't needed by digital cameras, so its just a naming convention now.

*An online search says that they needed sprockets and frame information, but I don't know that those mean either XD
