here is a good example of the Exposure triangle, i always said, that ISO, IS NOT, part of the exposure triangle, ISO is applied gain, and that happens after the picture has been taken, in Digital photography, not Film film is different.
ISO in Digital photography is Applied gain which happens after the picture was taken.
the first of the exposure triangle is Aperture, the second, is shutter speed, and the third, is SNR (Signal to Noise Ratio)
see turning up the ISO is degrading your signal and degrading your picture, each time you turn that ISO up a level higher your applying noise to your image.
now i'm not going to say any more watch this video which will explain this in great detail..
Any one who tells you that ISO is part of the Exposure triangle, doesn't really understand what digital photography is.
