Evening all, a quick question about ISO settings. Be it good or bad I've always left the camera set on auto ISO with the base threshold at 200 and the max at 3200. I can't say this has served me badly but there's a niggling thought that, not unlike the film days, I should manually select the ISO depending on the scenario, much like choosing a film speed and tailoring the parameters to suit. What's your thoughts and feelings on this topic?
