If your film canister says 800, you can’t simply adjust it back to 100.

Since the processes between film and digital are distinct, that means that they “read” ISO differently as well.įor instance, the film’s ISO is set. Meanwhile, in digital cameras, the sensor can change light into an electric signal that determines it. With film, the photosensitive chemicals determine the film’s light sensitivity. The main difference between film and digital is how they process light sensitivity. What is the Difference Between Film ISO and Digital ISO? Most modern cameras also start from 100, but can now go as high as 25,000 or even more. When digital cameras became the norm, they adopted the ISO system that film cameras used as well. ISO 800 would be perfect for night time photos because it is sensitive enough to record images in low-light situations. Meaning, you can only use it in the daytime. So how does ISO work? If a film canister says ISO 100, it has a relatively low sensitivity to light. Although, you can find ones as low as 25 and as high as 3200 in some cases. The common range you’ll encounter is 100-800. The higher that number, the more sensitive the film is to light. The acronym comes from the International Organization for Standardization, which developed the system.īack in the days of film photography, the ISO was marked on film canisters. ISO is a photography term that describes the sensitivity of your camera to light.
