What's going on kirk, I'm new to film photography. what does it mean to rate film?

What’s up!

To ‘rate’ film is to shoot it as though it were a different speed than what it says on the box. So I could 'rate’ Fuji 400H at ISO100 and shoot it as though it were ISO100, effectively overexposing it on purpose in every shot by 2 stops.
