What’s the film camera?

As the name implies, this is a camera that uses film as its recording medium. Digital cameras record images using electrical signals, but film cameras create pictures by exposing the photosensitive layer of the film to light.

What’s the half-size format?

Film comes in many formats, but the most popular is the 35mm format (36mm x 24mm frame size) — what we call full size in digital photography. The half size is a format in which two pictures (17mm x 24mm) are captured in a single 35mm-format frame, meaning that you can double the number of pictures that can be captured on a single roll of film — 72 pictures on a roll of 36-expsoure film, or 48 pictures on 24-exposure film.
