Just a quick question as I've been confused by a conversation with my little
brother about ISO's

I thought a higher ISO allowed a faster shutter speed in lower light, my
little brother thinks the reverse, ( I know it adds grain) so which of us is
right? does a higher ISO need more light or less?

Many thanks for settling what might seem a daft question, and I know theres
other variables..

Less. Who would use it if it took more light and looked worse?
