DEVELOPER D-76 DILUTED 1:1 WITH WATER*
(Time in minutes*)

(Note:  Kodak Developer D-76 diluted 1:1 is roughly equivalent to Sprint Developer diluted 1:9)
The following data has been updated from the most recent manufacturer's data sheets available March, 2001.  The times listed below apply to both 35mm and 120 film formats.

*Agitate continuously for the first 30 seconds, then gently for 5 seconds every 30 seconds thereafter.

**Kodak T-Max films exhaust fixer more rapidly than other films. If negatives show a magenta (pink) stain after fixing, the fixer may be near exhaustion or the film may not have been fixed long enough. If the stain is slight, it will not affect printing. If it is pronounced and irregular over the film surface, refix the film in fresh fixer.

DEVELOPER D-76 DILUTED 1:2 WITH WATER AT 75F*

During the summer months, it may be preferable to process your film at 75 degrees, since this is approximately the temperature of the running cold water, and since it is preferable to have all chemistry, including the final wash, as close to the same temperature as possible. To compensate for the increased activity of the developer at this higher temperature, dilute the D-76 stock solution from the tank 1:2 with water instead of 1:1 and use the following times:

This film can also be exposed at even higher ISO's, yielding unusual, grainy results, if developed in Kodak T-Max developer, as follows:

Extended Development with D-76 and Additional Dilution*

The data below are derived from The New Zone System Manual. Some photographers find that they are able to obtain a more evenly-developed negative with a better gradation of tones by diluting the developer more than 1:1 and then developing for a longer period of time. Note that all of the films listed below are exposed at half of the manufacturer's suggestion ISO in order to increase shadow detail. This method of using a lower ISO and the following development times with diluted D-76 may be especially useful when dealing with contrasty subjects.

Developing Kodak High Speed Infrared Film:

For best results, expose this film with a #25A (deep red) filter. In order to avoid fogging, the film should be loaded and unloaded from the camera in complete darkness. Do not remove the cassette from the plastic container except in darkness. Follow exposure recommendations on the data sheet included with the film; a trial ISO of 80 is recommended as a starting point. Bracket on your first roll to insure printable negatives.
