This question is probably directed at PE; I'm currently using the Fujihunt X-Press C-41 kit to process C-41 films; in various posts on APUG, stabilizer seasoning has been mentioned if I recall correctly. The Fujihunt solution contains 1,2-Benziso-thiazolin-3-one . Is there an advantage to re-using the stabilizer, thereby seasoning the working solution with processed films, or is the working solution (of stabilizer) best used on a one-shot basis? The process manual / leaflet doesn't give advice on this subject. Tom.
