Hi all - currently sorting shots from, er, July, and noticing that the noise is very variable - some shots with ISO 800 or even 1600 seem to have less than other shots with ISO 400 (I have an EP1 - and looking at unprocessed RAW files).
Other than the subject, kind of detail etc, I have read somewhere than sensors create more noise when heated, ie for the same scene and the exact same settings, I will have more noise with a camera that has taken several shots before, than with a camera that is taking its first shot.
Any experience with that, similar conclusions ? As an aside, any hints - things I can do to limit the noise at a given ISO ?
