Reuse
Checked 21 October 2026
Ilford says Ilford Ilfotec DD-X may be used for more than one film.
- 1+4 may be reused
Longer time for reuse: +10 % development time for each successive film in a litre (N, N+10 %, N+20 % ...), up to N+90 % for film 10.
Capacity, as the maker states it: 1 litre of 1+4 working solution reused: up to 10 x 135/36 or 120 films. Per litre of concentrate: 16 films one-shot, up to 50 reused.
For the highest image quality ILFOTEC DD-X should be used as a one-shot developer, however for greater economy it can be reused to process either several films individually or multiple films in batches. ... 1 Litre of ILFOTEC DD-X 1+4 can process up to 10 x 135/36 or 120 roll films provided that the developer is reused. ... Used at 1+4 for one shot processing it will develop 16x135/36 films. If reuse techniques are used, it will develop up to 50x135/36 or 120 films. ... ILFOTEC DD-X working strength solutions should not be kept for more than 24 hours.
