User manual CANON EF 28-135MM F-3.5-5.6 IS USM

[. . . ] You are assured of perfect exposures every time. Now you can concentrate on picture taking and stop worrying about mechanics. But before you actually load any film into your new camera, familiarize yourself thoroughly with the Canon EF 28-135MM F-3. 5-5. 6 IS USM 28-135MM F-3. 5-5. 6 IS USM and this instruction manual. Handle the camera, practice focusing, and use the winding lever. [. . . ] However, occasionally you will encounter picture-taking situations which require a departure from normal AE operation. For example: (1) Your subject is strongly backlighted or contrasts sharply with the background and will not appear in the center of the picture. (2) The entire scene is either extremely light, such as a light colored subject in snow; or it is very dark, such as a dark colored subject in deep shade or against a dark background. In the above cases, it is necessary to modify the automatic exposure reading which the camera normally sets by itself. The Canon EF 28-135MM F-3. 5-5. 6 IS USM 28-135MM F-3. 5-5. 6 IS USM provides a convenient way to do this by incorporating an AE memory lock button on the left side of the camera between the pentaprism and the ASA ring. By holding in this button, you can lock the meter needle of the camera at a particular f/stop while you change the position of the camera (and hence the view in the viewfinder). To produce a good exposure in the first situation (1) described above, focus on your main subject and center it in the viewfinder. If 32 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals the subject appears small, move in closer until it occupies about one-third of the total viewfinder area. Push the AE memory lock button and hold it in. Then you may step back and/or change the position of the subject in the viewfinder to suit your compositional taste, while the correct exposure reading is locked into the camera's Variable Aperture AE control. Releasing the shutter will produce a properly exposed photograph. · The multiple exposure button need not be depressed during the entire winding operation, but only needs to be held in at the beginning of the stroke. · In multiple exposure photography, exposures on the same frame of film are additive. In the AE mode of operation, the Canon EF 28-135MM F-3. 5-5. 6 IS USM 28-135MM F-3. 5-5. 6 IS USM automatically deter36 mines the proper exposure needed for a single frame. When making multiple exposures, less exposure must be given to each shot. One simple way to do this is to reset the ASA ring to a higher setting, which will fool the camera into decreasing the exposure reading. Multiply the normal ASA of the film by 2 for a double exposure, by 3 for a triple exposure, by 4 for a quadruple exposure, and so forth. However, when making multiple exposures of night lights or a subject against a black background, do not reset the ASA ring, because the black areas in the scene will become overexposed. Not For Resale ­ Free Download at http://www. joe-chan. com/manuals · In shooting fireworks, the recommended way to record multiple bursts on the same frame is not by using the multiple exposure button, but by mounting the camera on a tripod, setting the shutter speed dial at "B" and holding the shutter open with a cable release. Set the aperture ring manually to the appropriate f/stop, using the following table: ASA f/stop 25 5. 6 50 8 100 11 200 16 400 22 · Interesting motion studies can be made by mounting the camera on a tripod, using color film, and making a triple exposure through a red, a green and blue filter respectively. Select a scene having both stationary and moving parts, such as a seascape with rocks and surf, a crowded street with many moving cars and people, or a tree whose leaves are rustling in the breeze. Set the camera on a sturdy tripod, focus and compose in the normal way. Multiply the film's normal ASA by 3 and set this higher rating on the camera's ASA ring. [. . . ] If salt water spray or fingerprints inadvertently get on the lens, they should be cleaned off as soon as possible using commercially-available cleaning tissue and a good quality lens cleaning liquid. Put one or two drops of cleaning liquid on the tissue, and lightly wipe the lens in a circular motion from the center toward the outer edges. Do not use a handkerchief or other cloth, as the lens elements may be permanently scratched. If you cannot remove dust particles from the surface of the instantreturn mirror simply by brushing, you should not attempt to clean the mirror yourself with tissue and cleaning liquid. [. . . ]
