> image "noise" or "grain" that is introduced into a picture as you increase the ISO Not this absolute shit again. This is not how photography works or how physics actually work. Image noise does NOT come from high ISO, it comes from low exposure (not enough light hitting the sensor). ISO is just a multiplier between a number of photons and the brigthness of a pixel in your photo. The implementation of the multiplier…

ISO does not create noise. It amplifies (accentuates) the noise that is already there.
