Question: can you reuse ilford developer?
Answer: 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.
