Hi all, I am having problems developing 35mm B&W film in T-Max developer. My exposures are fine, I used different cameras but but my negatives come out underdeveloped. I use the Massive Developing app as a reference for times. I am agitating the first minute and then for 10 seconds every minute. Am I over agitating? What could be the problem? I used to use HC- 110 without a problem but now with T-Max I can not get a handle on it. As you can imagine the dissolution of seeing my photos ruined. Thanks in advance for your help. Raul
