what the hell does this even mean?

I’m shooting basketball in a dim gym so need fast shutter speed and high iso. can’t use flash to blind players. so your solution is to not shoot anything?

I’m shooting a concert, singer is jumping around, low light, I can’t use a flash. so don’t shoot?

I’m shooting owl that only flys and hunrs when it’s dark. just don’t shoot it?

high iso enables use cases that are difficult to capture other wise. that’s the whole point
