Kodak Tri-X

After exploring a series of different methods for developing 35mm black and white film at home, this is the process that gave me the most consistent results.

Based on a variation of semi-stand development, this process is very forgiving and doesn’t require exact time keeping.

I tested it on Kodak Tri-X 400 pushed to 1600, developing three rolls at a time and this is the setup I used:


3 roll Paterson development tank
3 Auto load reels
1 litre mixing jug
3 film clips
Mixer paddle
1 litre concertina bottle
Ilford Rapid Fixer
