You did't mansion which film you have exposed. In my experience I increase/decrease 20% for every push/pull process. As an example if I expose TMAX 400 into 100 iso I will make a pull process of 20%. My TMAX 400 is 5 minutes 10 second at 26 degree C . When I expose 400 into 100 iso my developing time is 4 minutes 8 seconds in TMAX developer at 26 degree. Every film is washed at normal water at 26 degree because the temperature will be the same. Agitation will be every 30 seconds. Hope you will find you answer.(posted 9424 days ago)Thank you Mohammad Irfanul Islam Darkroom Section Drik Picture Library http://www1.drik.net http://www1.drik.net/darkroom
