The - really - optimal ISO setting for a camera
Nov 17, 2012

I just have been told the fact I have already known but not really kept in mind that the digital sensors are have fixed sensitivity, the ISO changes done different hardware and software ways.

It means - theoretically - the camera have only one "best" setting or a very narrow range of the ISO values to present the highest dynamic range and the possible finest details. However changing the ISO it could lead loosing details either in the shadows or in the highlights.

I did google but mostly found "high iso means high noise" articles and nothing regarding the ISO settings and the fine details - I don't care about the noise at this moment, that is a different question. However I am really sure it is already discussed most probably in several forums and there is a camera/sensor database should be available for the theretically optimal ISO settings.

Anyone could help me to find information, facts regarding this question?
