How To Set The Iso - Canon AE-1 Manual

How to set the ISO

The ISO rating of the film is the level of sensitivity the film has to light. You must
choose the correct ISO setting for proper film exposure. The box the film came in and the
cartridge list the ISO speed of the film. Lift the knurled ring around the shutter speed dial
and turn it until the ISO speed of your film matches the green index.
