Use the Right Film Speed 

Films have different speed ratings (A.S.A. or I.S.O.). High-speed films (400ASA - 1600ASA) are good for low light conditions without flash or for freezing action. Medium-speed films (100ASA - 200ASA) are good for outdoors but fairly bright days. 

Low-speed films are good for bright sunny days or when maximum detail is required. The medium and low film speeds need a tripod or an extra artificial light like flash in low light conditions.
