Is Portra 400 DX coded?

Kodak Portra 400 is an ISO 400, daylight-balanced colour negative film that’s available in 35mm, 120, and large formats too. The 35mm cartridges are DX–coded with the number 115334.

Is Kodak Gold film DX coded?

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. According to Kodak themselves, you get saturated colours, fine grain, and high sharpness.

How does DX coding work on 35mm film?

How it works: DX coding is a system to allow cameras so equipped to read the film speed and other information from a 135 (35mm) film canister. The left hand row as shown above is the common contact and the conductivity of the other squares give the data. The top of the two rows of DX coding tells the camera the film speed.

Is there a way to read the DX code on a film?

The N80 has an automatic ISO function that can read the DX code of the film and shows me what it is on the display panel on the top of the camera.

What do you need to know about DX encoding?

They are used by photo finishers to identify each frame for printing. It consists of two parallel linear barcodes, one for a synchronizing clock, and the other encoding film data such as type, manufacturer and frame number. The outside of film cartridges are marked with a DX Camera Auto Sensing (CAS) code readable by many cameras.

When was the first DX encoded film made?

In contrast to former solutions like Fuji ‘s film speed encoding method in 1977, which was already using electrical contacts for film speed detection on 135 format cartridges, Kodak’s later DX code system immediately met success in the marketplace. The first DX encoded film was the color negative film Kodacolor VR-1000 in March 1983.
