User manual LEICA IIIA

[. . . ] This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ] By manually pre-selecting an appropriately fast shutter speed, you can therefore prevent unwanted blurring of the movement ­ you can "freeze" your subject. Or, in reverse, you can express the dynamics of the movement with a deliberate "wiping" effect using a correspondingly slower shutter speed. To set this mode, turn the aperture dial (1. 9) to the A position and set the desired shutter speed with the respective dial (1. 10). In addition, the manually set shutter speed appears ­ in white ­ (2. 1. 17). Press the shutter release button (1. 8) to its pressure point · The automatically set aperture appears in white (2. 1. 20). If even the fully opened or closed aperture in conjunction with the set shutter speed would result in under- or overexposure, both values turn red as an indication. If the automatically set aperture value seems appropriate for the intended composition: 2. Press the shutter release button all the way down to take the photograph. If not, you can change the shutter speed before pressing the shutter release button. Aperture priority mode Aperture priority mode automatically controls the exposure based on the manually set aperture. It is therefore particularly well suited for taking pictures where the depth of field ­ which is determined by the aperture used ­ is the crucial element of composition. By manually pre-selecting an appropriately low aperture value (= large aperture) you can reduce the depth of field, for example in a portrait to let a face "stand out", i. e. be shown clearly in front of an unimportant or distracting background. Press the shutter release button all the way down to take the photograph. Note: You can lock measured values any number of times before taking the picture. Exposure compensation Exposure meters are calibrated to a normal, i. e. If the relevant subject detail does not meet these requirements, for example large areas of snow or, in the opposite case, a black steam locomotive filling the frame, and if you wish to bias the exposure identically in such cases for a number shots, it may be more convenient to apply an appropriate exposure compensation than to use metering memory lock every time (see previous section). To set a compensation, press the upper EV/direction button (1. 20) once. Select the desired compensation value with the left and right direction buttons (1. 25/1. 22). · While setting, you can observe the effect as the monitor image gets correspondingly darker or brighter. Confirm the setting by pressing either the shutter release button (1. 8) or the MENU/SET button (1. 23). · The exposure compensation symbol and the set value (2. 1. 21) appear. 106 Notes: · An exposure compensation cannot be set when using manual exposure mode (see p. 105) · The EV/direction button is also used to call up the menus for exposure bracketing (see next section) and flash exposure compensation (see p. They scroll through in an endless loop and can therefore be selected by repeatedly pressing the button. · A set compensation remains active until it is switched to ±0 (see step 2. ), i. e. [. . . ] · To prevent the formation of fungus, do not store the LEICA IIIA in a leather case for extended periods of time. · Note the serial numbers of your LEICA IIIA, as it is extremely important in case of loss. 129 Technical data Sensor APS-C-size (23. 6x15. 7 mm) CMOS Sensor with 12. 9 Megapixels, aspect ratio 3:2 Resolution Selectable for JPEG format: 4272 x 2856 pixels (12. 2M), 3264 x 2160 pixels (7M), 2144 x 1424 pixels (3M), 1632 x 1080 pixels (1. 8M), DNG: 4288 x 2862 pixels.
