Quick Summary
- Kodak uses edgeprint codes for 35mm (135) and medium-format (120/220) film stock, including black and white, color negative, and color transparency films.
- Edgeprint codes are exposed onto the film edges outside the sprockets, providing information about the type of film.
- While some manufacturers simply include the film name in the edgeprint, Kodak often uses codes, which can be cross-referenced with film types and names.
- The article provides tables detailing the edgeprint codes for various Kodak film stocks, including black-and-white negative, color negative, and color transparency films.
I recently started scanning decades’ worth of old film negatives and slides — mostly Ilford, Kodak, Fujifilm, and Agfa — that had been taking up office space.
I’m culling and disposing of many of the tens of thousands of negatives that I’ve accumulated over the years — yes, I know it’s sacrilegious, but it’s time.
I wanted to record the specific film stock for each shot. In the digital age, EXIF data handles this automatically, but with film, that data is easily lost. In many cases, I recorded some shooting and processing data on the negative sheets when I developed and filed them. Things like the camera used, the developer used, and whether it was push processed.
It can also be very useful to know the specific kind of film stock used. And it can be more than a matter of record-keeping; it can affect how you digitally edit the images, especially if you’re using something like Negative Lab Pro.
Fortunately, manufacturers helpfully exposed the film type directly onto the film edges, outside the sprockets. It’s known as the edgeprint code, and on Kodak film it’s at 2-inch intervals at the top, above the sprocket holes. There’s a practical example at the top of the page; in that case, it’s Kodak T-MAX 400 black-and-white negative film (5053 TMY).
Some manufacturers, such as Ilford, make things easy with their edgeprint codes — they just include the name of the film, such as HP5, Pan-F, FP4, or XP2.
Kodak does that with a handful of their film stocks, but on many, they make things a bit more confusing by using codes. And if you’re not using them in day-to-day shooting anymore, it’s easy to forget what codes apply to which film types. Which is where the table below comes in. It cross-references the films’ edgeprint codes with the film types and names.1
I’ve broken it out into main film types and whether the film was color negative, color transparency, or black-and-white.
And while I’m mainly working with 35mm / 135 stock, I’ve also included several medium-format 120/220 codes. I’ve not included some of the other, more specialized formats that are available in some cases, such as sheet film or movie film stock.

Things worth knowing
DX Code. Newer film canisters (or magazines) often include what’s known as a DX code (this has nothing to do with Nikon cropped-sensor digital cameras, in this case). These are exposed metal parts of the canister that are configured into a very basic barcode pattern. For newer cameras that could read them, these DX codes conveyed to the camera the nominal film speed (ISO) of the film, reducing the need for the photographer to have to remember to manually adjust the ISO when they inserted the film.
They also served another purpose for film processing machines used in development labs through a latent-image bar code along one edge of the film that conveyed information such as the film family, film generation, film type, and number of exposures. Kodak also deployed a machine-readable Keycode for this latter purpose.
Standard photography film in 35mm (135) and medium-format (120/220) is often available in ready-to-go film canisters (or magazines, as Kodak refers to them) or on long bulk rolls that the photographer can load themselves into film canisters for use. In some cases, there are minor differences in the markings between these films.
Push / Pull. Film stock has a nominal ISO rating, which is the sensitivity that the manufacturer has determined that the film performs at optimum levels with standard processing. But you can also push and pull film, which involves deliberately treating the film as a high or lower ISO film. That has the effect of underexposing or overexposing the film.
Sometimes it’s done as a pragmatic adjustment for lighting conditions. Or it might be done as a creative choice for different visual results. Adjustments are then made in the processing, sometimes by adjusting the developer time, using a different developer chemical, or increasing the developer liquid’s temperature. Some films are more forgiving of pushing and pulling than others.
Slide film can go by many names: color reversal, color transparency, or chrome film.
Motion picture film stock uses different coding styles. You can find Kodak’s guide to those codes here and a guide to reading film can labels here.
Notes & References:
- The starting point for this information is Kodak’s Reference Dataguide: For Kodak Professional Photographic Products (1994; publication PG-118). I’ve built on that with newer and updated films using other Kodak technical data guides when available (such as this one), as well as technical guides for individual film stocks. This is a running list and doesn’t include every film Kodak has ever made; let me know if there’s something missing that you think should be added. [↩︎]
