Manufacturer's Technical Publications


Film and Chemical technical data sheets from the manufacturers. If you're trying a new film or developer, and I don't have developing times listed for it, the manufacturers are your best starting point. Because these publications are not always easy to find on the manufacturers' websites, I have gathered links to them here.

All of the links will open in new tabs as PDF files.


Kodak B&W Films and Chemicals:


These are the tech data sheets for the current version of Kodak's black & white films. Note that all of these films were reformulated several years ago, and the developing times for them changed! Use these publications only for the current versions of Kodak films.

Tri-X 400

Tmax 100

Tmax 400


Discontinued Films

My tech sheets for discontinued Kodak films are the last versions that Kodak published before they stopped making these films.


Verichrome Pan

High Speed Infrared



Kodak no longer has any tech publications for their chemicals online, so these are from my archives. The developing times listed in them should NOT be trusted, as Kodak has reformulated their films since most of these tech sheets were published.

I am presenting them here because they're of interest to those who still have some of the older versions of the films in their freezers, and because the developer data sheets still have useful information about capacity and shelf life that has not changed.

These are the last versions of the chemical data sheets that Kodak published.



Tmax and Tmax RS Developers





Ilford B&W Films:

These are the current versions of Ilford's technical publications for their black and white films. They should be considered accurate only for the current versions of these films, since older versions may require different developing times.

HP-5 Plus

Tech data sheets for Ilford's Delta black and white films.

Delta 3200



Agfa B&W Chemicals:

This is the best version I have of Agfa's recommended developing times for Rodinal developer. It includes times for dilutions higher than 1+50 for some films. This info sheet is also more accurate than Agfa's later tech documents for Rodinal, which indicated strangely long developing times for many Kodak and Ilford films.

Keep in mind that Kodak has reformulated ALL of thier black and white films since Agfa's demise, so the developing times for Kodak films may not be correct. See my Tested Developing Times for correct Rodinal times before you use the old Agfa data I am offering below. The Agfa recommendations are a good starting point for old versions of Kodak films, or for films I have not tested in Rodinal.
