So I had a roll of Kodak Ektar 100 loaded in my Olympus OM-1. Anyways long story sort I realized this afternoon that I had forgotten to adjust the iso, but rather left it at 400. Now this is bad enough. However Wednesday I was helping a friend develop her first roll of film, which happened to be a roll of Ektar that had been shot at iso 400. Because she forgot to adjust the iso as well. So naturally I reminded her that she needs to make sure she readjusts the iso as per the film requires. Maybe I need to take my own advice more often.
