I have a theoretical question for you guys...
Given an average ambient temperature, would an image exhibit higher IQ/less noise with a shorter exposure at higher ISO, or a longer exposure at a lower ISO? I caught this comment by Thierry in another post (about the eMotion 75 @ 800 ISO):

I have no idea if this a valid theory or not, and it probably differs greatly on the type of back. Any insight or real world experience on this?It also depends on the ambient temperature when your are shooting: my guess (but it's only a guess) is, that it will give a better result with ISO 800 at 4 sec. than at ISO 100 with 30 sec.
