Dark Room Developing

Chemical Processes

Step 1: Developer- 1:1 mix

How to mix the developer.

When mixing the developer and water, take the temperature of the developer first and then match the water, (150ml of water and developer at 20 degrees) 

Example- If your developer reads 22C, you would have to make your water 18C. So when you mix the two together, the temperature will be 20C. 

Developing times: PAN (50 ISO) = 8 - 9 minutes 

FP4 (125 ISO) = 12 minutes 

HP5 (400 ISO) = 14 minutes 

Step 2: Stop Bath 

(pre-mixed from the bottle) 

Stop Bath = 300ml for 30 seconds - Film facedown

(The chemical used, can be re-used)

Step 3: Fix 

(pre-mixed from bottle) 

Fix = 300ml for 5 - 7 minutes 

Agitate film for 5 seconds every 30 seconds untill film is fully fixed.

Step 4: Wash

Wash the film for 10 minutes in a tray of cold, clean water. 

Step 5: Drying

Dry film in a film dryer can take unto 5-15 minutes depending on the temperature
