Understanding ISO settings

This was a great page in terms of understanding ISO settings and how they work better. I think with this along with the page that highlights the native and best ISO shootings to shoot with on DSLR I feel very comfortable in terms of knowing what ISO settings to shoot on. Another things I have read about is how the Magic Lantern software can set the camera so it only uses the best ISO settings to ensure only the best ISO settings are used for shooting with. This is something that I will look more into and see how exactly it works as I have been meaning to read and understand Magic Lantern better.
