High ISO only in low light, or???
Several times I noticed people shooting pictures at 400-800 ISO, resulting in very fast shutter times, even for landscape pictures with no moving objects.
I would have thought one would use the lowest possible ISO to avoid noisy pictures, unless there is the risk of motion blur.
Why are they doing that? Is there an IQ reason to do so or did they just forget to switch the ISO values back to the normal (low) settings?
