8 EXPOSURE The film requires exactly the right amount of light to create an image.

9 EXPOSURE how much light do I need? how to control the amount of light reaching the film?

10 EXPOSURE how much light do I need? how to control the amount of light reaching the film? light meter, usually built in to the camera

11 EXPOSURE how much light do I need? how to control the amount of light reaching the film? light meter, usually built in to the camera aperture and shutter controls on your camera

12 APERTURE The aperture is a hole whose size can be varied to allow more or less light to pass through it. The smaller the f-number is then the larger the aperture is and the more light it will pass.

13 SHUTTER SPEED the length of time a camera shutter is open. longer shutter speeds allow more exposure because more light strikes the film.

14 SHUTTER SPEED

15 Shutter values follow a standard sequence with each one being half that of the next, allowing half as much light to pass through. 1sec; 1/2sec; 1/4sec; 1/8th; 1/ 15th; 1/30th; 1/60th; 1/125th; 1/250th; 1/500th; 1/1000th; 1/2000th When a camera shutter is open, any objects, persons, etc. in front of the lens are recorded on film. Anything that moves across the field of view while the shutter is open will be recorded as a blur.

16 SHUTTER SPEED 1/30th1/250th1/1000th High shutter speed Low shutter speed

17 SHUTTER SPEED High shutter speed = freeze the action

18 SHUTTER SPEED High shutter speed = freeze the action

19 SHUTTER SPEED Low shutter speed = idea of movement

20 SHUTTER SPEED Low shutter speed = idea of movement

21 SHUTTER SPEED - QUIZ High Shutter speed Slow Shutter speed OR

22 SHUTTER SPEED - QUIZ High Shutter speed 1/1000s

23 SHUTTER SPEED - QUIZ High Shutter speed Slow Shutter speed OR

24 SHUTTER SPEED - QUIZ Slow Shutter speed 1/125s

25 MAKING IT ALL WORK TOGETHER The quantity of light to correctly expose a film is constant.

26 MAKING IT ALL WORK TOGETHER

27 FILM LOADING 1. Open the camera back by pulling the film rewind knob all the way out. 2. Install the cassette in the film chamber and push the film rewind knob back in.

28 FILM LOADING 4. Slide the film advance lever out past the ridge of the camera with your thumb and advance the film slightly until I the sprocket teeth properly catch the perforations on the edges of the film. Close the camera back and press until it locks in place. 3. Insert the tip of the film into one of the slots of the take up spool

29 FILM - iso A normal film will be rated at ISO 100 ISO = film speed A film rated at ISO 200 will give a proper exposure with only half the amount of light compared to the ISO 100 film, enabling you to shoot in lower light.
