Do you know about film?
What is ISO?
ISO describes the sensitivity of film to light. The
greater a film’s ISO rating, the more sensitive it is.
Usually, color negative film of ISO 1CX), 200 or 400
is used.
What Is DX-coded film?
DX coding informs the camera of a film's ISO
sensitivity, so the camera can self-adjust to the
film’s speed. Almost all negative-color film is DX-
coded.
