Looks like this guy is making beginners more confused.
Comparing low vs high ISO as same shutter speed, then of course the low ISO picture will be darker. Then increase brightness digitally to show more noise and say lower ISO more noise.
Try to shoot picture at correct exposure with low ISO and also with high ISO, meaning the low ISO one with longer exposure compare to the high ISO one. This will give both picture with same brightness. Then magnify the picture to see which one is grainier. I can bet the the one with high ISO will have more noise.
Your statement is only valid looking at one perspective.
Anything for view count these days. Obviously, you could use higher ISO, it just depends on situation. People who stick to 50-100 guideline just tend to stay safe and don't like to do much of tests or trial. But to say lower ISO produces noisy photo compared to higher ISO is just misleading.Comparing low vs high ISO as same shutter speed, then of course the low ISO picture will be darker.
