What do the numbers on a roll of film mean?

The ISO number is essentially an indicator of how sensitive the film is to light – it’s also often referred to as film speed. You’ll find this number on the side of any type of film and common ISO numbers include 100, 200, 400 and 800. The lower the number means the lower the ‘speed’ of the film.

Is Fuji Film DX coded?

DX-iX (data exchange – information exchange) is an expanded DX encoding system introduced in 1996 to be used in conjunction with the Advanced Photo System (APS). In 1998, Fujifilm introduced a film identification system for 120 and 220 format roll film called Barcode System (with logo “|||B”).

Is Kodak Gold DX code?

Kodak Gold 200 is a 5500k daylight balanced, ISO 200, colour negative 35mm film that’s available in rolls of 24 or 36 exposures. It has the DX code 512504 and is developed using the regular C-41 process.

Does ISO matter in film?

Set the Film ISO ISO is the film sensitivity. It’s a number, more common ISOs are 100 and 400. The higher the ISO, the higher the film sensitivity and the larger the film-grain size. The good thing about low-ISO film is that the film-grain is very fine and you have a lot of detail.

How do you find the speed of a movie?

Film speed is determined by an ISO number (in the UK/US this used to be known as ASA). You will always find a number on your box of film. This ISO indicates how sensitive the film is to light. It lets your camera or light meter know what other settings are needed to get a good exposure.

Is CineStill DX coded?

Now DX-Coded! CineStill film is the amazing technology of motion picture film, prepped and rolled for still photography. CineStill 800Tungsten is a unique film for still photographers.

Are all 35mm film DX coded?

All brands of 35mm film that we see available now from Kodak, Ilford, and many others still use DX encoding. However, it has not been completely without controversy over the years. DX coding is something that many film photographers will already be familiar with.

What is ASA in film photography?

The ASA (American Standards Association) scale is an arbitrary rating of film speed; that is, the sensitivity of the film to light. If everything else is kept constant, the required exposure time is inversely proportional to the ASA rating.

What speed film should I use?

Medium speed is 400 ISO. As can be expected, the medium speed is probably the best for general-purpose use and can handle indoor lighting conditions, overcast days and any combination of the two. Even so, it’s not suited for action shots or very bright days. Fast-speed film is usually rated at 800 ISO and above.
