The Canon EF is a complex instrument having a multitude of advanced features, yet it is incredibly simple to use. Just select a shutter speed and the camera adjusts its own diaphragm for you automatically under all kinds of lighting situations, from bright sunlight at the beach to dim candlelight. [. . . ] In the second situation (2) above, the scene cannot be metered directly. Most scenes are composed of both light and dark areas which usually average out to a medium gray. Because all TTL exposure meters are calibrated to give proper exposure when reading a neutral gray card (of 18% reflectance), they give correct exposure for most scenes. In extreme cases in which the scene is predominantly light or predominantly dark, the Variable Aperture AE control must be fooled into providing the correct exposure. One readily available alternate subject is the palm of your own hand held out a foot or so in front of the lens and placed in the same light as your original subject. Then fill the viewfinder with the out of focus image of your right palm making absolutely sure that it is in exactly the 33 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals BASIC OPERATION same light as your main subject. Push in and hold the AE memory lock button with your left thumb. Return your right hand to the camera body and release the shutter. The exposure you locked in will be close to the proper exposure needed for a very light or very dark subject. · In practical terms, the exposure latitude of both black and white and color negative film (from which prints are made) is inherently large enough to overcome almost all AE maladjustments which occur in day-to-day shooting. Therefore, it is not mandatory to use the AE memory lock button at all. However, color transparency film has extremely small exposure latitude and requires near perfect exposure to produce good results. When taking color slides, the use of the AE memory lock button in the special situations previously described is strongly recommended, · A standard 18% reflectance gray card is a much more accurate surface to meter than the palm of your hand. It may be purchased very inexpensively from your local camera dealer and carried with you for situations requiring nothing less than perfect exposure. 34 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals J Releasing the Shutter The Canon EF's shutter button is conveniently located on the right side of the camera and is coaxial with the winding lever and shutter speed dial. The shutter button stroke is very light and short for a Variable Aperture AE camera. As a built-in safety feature, the shutter button is locked automatically when the camera is turned off. 35 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals BASIC OPERATION K Making Multiple Exposures Exposing the same frame of film with two or more images is an exciting technique used by many photographers to create dream-like scenes, abstract designs, motion studies, or humorous pictures. Your imagination is the only limiting factor in this creative process, because Canon has made multiple exposure photography so easy to perform with the EF camera. A multiple exposure button is located in the center of, the ON/OFF switch. After making your first exposure, hold in this button with your left thumb while operating the winding lever in the normal way. The movement of the film transport sprocket is stopped, while the winding lever re-cocks the shutter. Now you are ready for your next shot which will be in perfect registration directly on top of the first shot. This process may be repeated any number of times, and the frame counter is stopped until the film is actually advanced to the next frame. [. . . ] Only an authorized serviceman should undertake this delicate task. Actually dirt on the mirror has absolutely no effect on the quality of your photographs. B Storing the Camera If the camera will not be used for an extended length of time, leave the shutter uncocked and remove the mercury batteries. Take the camera out . of its eveready case and wrap it up in a clean, soft towel together with silica gel or some other desiccant to keep it dry. C Using the Camera in Extremely Cold Conditions In severely cold weather (down to ­20 C or ­4°F), you should keep the Canon EF inside your coat and expose it to the outer air only when you are ready to take a picture. This procedure is necessary primarily to keep the mercury batteries warm. [. . . ]
