[QUOTE="Griso, post: 548542, member: 36326"] Hi Fred, I'll rattle these off one by one if that's ok 1) As I'm sure you know, when using AutoISO, the camera will adjust the exposure to achieve what IT thinks is the optimum exposure. However, if you're shooting something very white, the camera will try to under expose it to achieve the (18%?) grey. If you're shooting a bird against a bright sky, the camera will expose for the sky giving you a very underexposed subject. etc etc., but I hope this unconfused you :) 2) err, yes, I'm shooting RAW and post processing. I'm honestly slightly surprised (verging on flabbergasted to be honest!) that someone asking how to adjust ISO would have the implicit suggestion that he's a complete numpty, doesn't shoot RAW, or post process (although as we all know there are very good and legitimate reasons for shooting JPG and using in camera processing, but let's not go there now). Anyway, I do hope this leaves you in a slightly less confused state and we can get back onto 'how do you press the ISO button without your left hand?!!' [/QUOTE]
