User manual OLYMPUS OM-PC

[. . . ] Thank you for choosing the Olympus OM-PC. This camera is equipped with a unique "ESP" (Electro-Selective Pattern) metering system. By combining this metering mode with the automatic film speed setting mode and programmed exposure mode, anyone can take perfectly exposed pictures with ease. Before using the camera, please read this operation manual carefully through while checking with your camera to become familiar with this versatile SLR. Note: All the components of the Olympus OM-PC are carefully designed and their production and assembly is strictly controlled to enhance the unmatched performance of the system. [. . . ] When using a super wide angle lens in situations where the sky unavoidably forms a large part of the composition, it may be useful to set a plus exposure compensation. When using together with ESP Metering mode, exposure compensation set by the ESP Metering system are added to those that are manually set. 51 DX ISO AUTO Film Speed Setting Film speed information is recorded in the digital pattern imprinted on the cassette of DX type film. The OM-PC reads this information through the electrical contacts located at six positions in the film chamber, and conveys it to the camera's computer. On reading this information, the film speed is automatically set on the camera. In other words, when you turn the OM-PC film speed dial to the DX ISO AUTO SET position, whatever the film speed it is automatically set on the camera. There is no risk of getting a mistaken setting when you change to a different film speed . . . When using the DX ISO AUTO setting, first make sure that you are using DX film. Also note that if there is any damage to the digital pattern on the film cassette, this could result in a mistaken film speed setting. ISO Manual Setting The OM-PC also allows manual setting of the film speed in exactly the same way as previous cameras. Also use this mode at times when you wish to set an exposure compensation on the dial. Exposure compensation Whether it is in the programmed exposure mode, automatic exposure mode, or manual mode, the OM-PC permits exposure compensation with the exposure compensation dial. (Remember, exposure compensation is not possible in the film speed auto-set mode. ) For example, if the background is brighter than the subject (backlighting), turn and set the dial to the (+) side. This will provide more light for the subject. As you turn the dial, the sign will blink in the viewfinder and the displayed shutter speed will shift depending on the amount of compensation. The dial can also be set at the intermediate click + 2 Stops positions providing accurate 1/3 stop + 1 Stop exposure compensations. 0 ­ 1 Stop -2 Stops 52 BULB EXPOSURE If you require long exposure, set the shutter speed dial at "B" (bulb). This is useful for night exposures or other special effects. * When taking pictures with the shutter speed dial set at "B", it is recommended that you use a tripod and cable release to prevent camera shake. 53 MULTIPLE EXPOSURE By tripping the shutter several times on the same frame, multiple images are produced on the same frame. This is how to do: INFRARED PHOTOGRAPHY After the first exposure is ended, erect the rewind crank and turn it clockwise as far as it will go to take up film slack. While holding both the rewind knob and rewind button with your fingers to prevent them from moving, wind the film advance lever. In fact, the film is not wound and the shutter is cocked by this operation. Press the shutter release as you would do normally, and double exposure will occur. By repeating the steps and , the frame will be exposed as many times as you want. However, the frame counter advances each time the shutter release is pressed. After ending the multiple exposure, put the front lens cap on and make a blind shot. Note: The frame may shift slightly. When shooting infrared pictures with infrared film and a red filter, the point of focus will slightly differ if you focus visually. The amount of shift varies with the lens and a red line or red dot is marked on the lens' depth of field scale to compensate for it. First, focus the lens without a red filter on as you would do normally. Next, read that distance on the distance scale and shift it opposite the infrared mark, then put on a red filter and shoot. (The above picture was taken with the distance at infinity. ) 54 55 Flash Photography The OM-PC is designed to provide "OTF" Automatic Exposure with Olympus T-Series electronic flashes. There is nothing to set since exposure is determined by the sensors in the camera body itself. [. . . ] Aperture-Preferred Automatic Exposure: Type; Automatic exposure control with aperture-preferred electronic shutter. Auto Flash Exposure: Choice of "OTF" Auto Flash or "OTF" Program Flash. Direct contacts for "OTF" Auto Flash. (Full automatic f lash with TSeries Flash); Automatic shutter speed setting for flash exposures. [. . . ]
