Discontinued & Obsolete

The following films and developers are no longer in production. You may find more data in the main chart if the film has been recently discontinued. If you are developing old film which has not been refridgerated or frozen you will probably need to extend the times given here. If you have an old pack or bottle of any developer, it will almost certainly have lost some or all of its activity and should not be used without testing.
