I just got into film and just bought a Very cheap canon 518 auto zoom on ebay. Everything works on it , so I bought film and am waiting for it to arrive. In the meantime I planned a trip to go skiing and just wanted to know what to set the exposure at. When I go outside with the camera and have the exposure on AUTO it always gets overexposed, but when I switch it to MANUAL, I can get the meter to stay towards the middle. Does this mean that the film will be exposed correctly when shot in bright conditions like skiing. I orded Kodachrome 40, which is like an all purpose film I guess. Any advice would be great. Thanks
