RECOMMENDED CAMERA SETTINGS
A good place to start when determing exposure with an SLR is 1/1000th of a second at F/4.0. Often this exposure can be reached when using 100iso film. If you are shooting with Provia100, rate it in the camera as 80iso film instead of 100iso. The shots will be brighter and more vibrant.
Shoot lots of film! You won't produce outstanding images on your first roll. It may take 10 rolls to get good pictures...it may take 50 rolls. Don't be afraid to shoot 5-10 rolls in one day with your buddies. A quick statistic: National Geographic photographers shoot an average of 5,000 photos for every one shot run in the magazine. Film is cheap, but a great photo is priceless.
Lastly, have fun with it!
