Foreword Congratulations on purchasing our mecablitz 34 CS-2 digital and thank you for the confidence in Metz products. The following pages give useful instructions for proper operation of the mecablitz and a survey of all its sophisticated functions. Please read these operating instructions carefully, even if they do not appear to be very interesting at first sight. [. . . ] The mecablitz can also be used for fill-in flash in daylight to soften harsh shadows and lower the contrast, thereby producing a more balanced exposure when shooting against the light. Use the camera, or a hand-held exposure meter, to establish the required aperture and shutter speed for a normal exposure. Ensure that the camera's shutter speed either equals, or is slower than, the fastest flash synch speed (varies with different camera models). (see operating instructions for your camera) The two established values for aperture and shutter speed can be set on the camera because the camera's shutter speed is slower than the camera's flash synch speed. To maintain a balanced range of highlights, for instance in order to retain the character of the shadows, it is advisable to select the automatic aperture on the flashgun one setting lower than the aperture adjusted on the camera. 6 is not available on the flash unit because of the adjusted film speed, then the problem can be overcome in the following manner: Select an auto-working aperture of f/8 on the mecablitz and set a shutter speed of 1/30th sec. If an auto-working aperture of f/4 were to be set on the mecablitz, then a camera aperture of f/5. This would fall short of the camera's flash synch speed of 1/100th sec. When shooting into the light ensure that the backlight does not shine directly onto the sensor as this will confuse the flashgun's electronics. Automatic exposure systems are based on a reflection factor of 25%, this being the average degree of reflection for subjects shot with flash. A dark background that absorbs a lot of light, or a bright background that bounces off a great deal of light (e. Backlit scenes), can result in overexposure or underexposure of the subject, as the case may be. To compensate the above described effect, exposure can be corrected by opening or stopping down the camera's aperture. If the background is mainly bright, the flashgun's sensor will cut off the flash too soon with the result that the subject will be underexposed. With a dark background the flash is cut off too late so that the subject looks too light. Indicator lights up only when the picture will be, or was, correctly exposed in the auto mode. Indicator remains dark after the test flash was fired, then set the next smaller f-number or diminish the distance to the reflection surface or subject, and repeat the test flash. to trigger a test flash , hold the camera and the flashgun in the same manner as for the actual shot. There is no exposure verification on the SLAVE unit in the cordless Metz remote mode. Only the indication on the controller (master) is relevant for correct exposure confirmation. If there is no attachment in front of the reflector, the mecablitz provides full lighting coverage for normal 24x36mm shots with lenses of 35 mm focal length and longer. If a wide-angle diffuser (identified by W) is used in front of the reflector the flash will cover the image angle of a 24mm lens. [. . . ] In such an event close down the aperture on the camera or mount a neutral density filter in front of the lens. It is quite sufficient to briefly switch the mecablitz off and on again with the main switch to leave the , , SLAVE mode with the cordless Metz remote system" for the , , mecalux SLAVE mode with preflash suppression" (SLAVE function selector in position 2). , , In position 1 of the SLAVE function selector , the mecablitz always operates with the , , mecalux SLAVE mode. The SLAVE only reacts to a light pulse from the controlling , , master"-. [. . . ]
