We should begin by saying that the point of all of this is not just to criticize one of the most repeated photographic myths out there – that's just a tool, because an incorrect understanding of the way that exposure and ISO work, as well as their roles during the shooting process, leads to a falloff in the quality of shots that photographers get.

So our goal is to show how, by rejecting this myth, you (the now-enlightened user) will be able to more fully utilize the capabilities that your camera has, as well as to improve the quality of your photographs.
