KODAK Self-Teaching Guide to Using an Adjustable 35 mm Camera

Find the shutter speed settings on your camera and learn how to change them. Your camera instruction book will explain how to do this. Shutter speed settings are usually numbered 30, 60,125, 250, 500—or on older cameras 25, 50, 100, 200. The numbers refer to fractions of a second, such as 1/30 or 1/500. All further reference will use only the settings for newer camera (30, 60, etc). If you have an older camera, just remember that 30 is about the same as 25; 250 is about the same as 200.

Find the lens opening settings (f/22, 16, 11, 8, 5.6, 4, 2.8) on your camera and learn how to change them (see your camera instruction book).

THE SHUTTER

Set the lens opening on your camera at its largest opening (f/3.5 or f/2.8). Set the shutter at 30. Now open the back of your camera. Be very careful not to get your fingerprints on the inside of the camera or on the lens. Touch only the outside parts of the camera. Never touch the lens or the inside parts of the camera. Hold the camera up and look into the lens through the back of the camera. Press the shutter release and see how long light is let through the lens. The shut- ter was open for only 1/30 of a second. Now advance the camera once and set the shutter speed at 250. Hold the camera up and look through the back as you did before. Press the shutter release. The shutter was open for only 1/250 of a second. Compare several different shutter settings to get an idea of how they relate to each other. Starting at the fastest shutter setting, each smaller setting lets light in twice as long as the one before it.
