Do not open camera before film is completed and rewound. Follow the arrow on the rewind crank. Check for obstructions before you shoot a picture. Fluorescent light gives a more greenish tone. Try using a flash for indoor shots or a light balancing filter for fluorescent lights.
Some cameras automatically adjust exposure for the lightest area.
Try using a flash or reposition your subject. If you take a flash picture too close to the subject, the excessive light will cause the subject to be overexposed. Stand-back a few feet. Flash shots are not good for close-ups. Store film in a cool, dry place.
