Reuse
Checked 21 October 2026
Ilford says whether Ilford Ilfotec LC29 may be reused depends on how it is used.
- 1+9 may be reused
- 1+19 may be reused
- 1+29 use once
1+9: +10 % development time for each successive film in a litre (N, N+10 %, N+20 % ...), up to N+90 % for film 10.
1+19: +10 % development time for each successive film in a litre (N, N+10 %, N+20 % ...), up to N+40 % for film 5.
Capacity, as the maker states it: Reused working solution: 10 films per litre at 1+9, 5 films per litre at 1+19; 1+29 is one-shot.
With ILFOTEC LC29 there is a choice of dilution - 1+29, 1+19 and 1+9 - and the option for either one-shot processing or for greater economy to reuse the diluted developer solution during one working session. ... Working strength solutions of ILFOSOL S 1+9 and 1+14 and ILFOTEC LC29 1+29 are described as a one-shot developers. They should be used only once and discarded, we do not recommend reusing them to process more than one film. ... For the highest image quality ILFOTEC DD-X 1+4 and ILFOTEC LC29 1+9 and 1+19 should also be used as one-shot developers. For greater economy they can be reused to process either a number of films individually or multiple films in batches.
