using pentax me super
i have a pentax me super that i’ve never used before and it’s my first proper film camera. it is stuck on automatic at the moment (going to try get it fixed) and already has a roll of film loaded i think as it’s taking photos and the counter is going up (although i thought they usually went down). I read in the manual that the roll of film will tell you what settings to have your camera on but because i didn’t buy the original film i have no way of knowing. i usually work with digital and i’m very unfamiliar with film. i want to take my camera to an upcoming concert mainly to photograph the people but how do i know that i’ve got the aperture, exposure etc right? i’d hate to get it developed and it all be over or under exposed
