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 100, 200 or 400 is used.
What is DX-coded film?
DX coding informs the camera of a film’s ISO sensitiv¬
ity, so the camera can self-adjust to the film’s speed.
Almost all negative-color film is DX-coded.
