Troubleshooting-continued LCD panel - Viewfinder Cause ‡ blinks for 3 sec. after flash • Flash has fired at full output and underexposure may have occurred. Err blinks Err blinks • Malfunction detected. Remedy Page • Shoot again after confirming focus distance, aperture or flash shooting distance range. 91, 97, 98 • Turn the power off once and then on again. If the warning indication remains, or this warning appears frequently, contact authorised Nikon dealer or service centre. In certain cases, due to static electricity, the F75/F75D's microcomputer may turn the camera off, even with fresh, properly installed batteries. For the same reason, the film may not advance properly. In each of these cases, to resume operation, simply turn the power off, then turn it on again. Or, remove and reinstall the batteries. 120 Glossary CPU Central Processing Unit. The electronic component that controls an electronic product's functions. AF Nikkor (including G- and D-type AF Nikkor) and AI-P-Nikkor lenses have built-in CPUs. Depth of Field See the column on page 102. EV Exposure Value: A number representing the available combinations of shutter speeds and apertures that give the same exposure effect under conditions of similar scene brightness and ISO. At ISO 100, the combination of a one-second shutter speed and an aperture of f/1.4 is defined as EV1. The camera can be used only within the EV range of the exposure meter. For example, with the F75/F75D, the exposure metering range is from EV1 to EV20 at ISO 100 with an f/1.4 lens. Exposure See the column on page 32. Exposure bracketing Shooting the same subject a number of times at a range of different exposures to attain proper exposure. Three shots with metered EV, under EV, and over EV exposure are performed in that order with the F75/F75D. Automatic exposure bracketing is performed with varied shutter speeds and/or apertures. Exposure Compensation In a situation such as when your subject is strongly backlit, exposure compensation enables you to intentionally compensate the standard exposure value measured by the camera to create a desired effect. Exposure compensation of -3 EV to +3 EV in 1/2 steps is available with the F75/F75D. Flash shooting distance range The distance range over which a flash can effectively provide light. Flash shooting distance range is controlled by the amount of flash output available. Each automatic Speedlight's flash output varies from maximum duration to minimum duration. Close-up subjects will require lower (to minimum) output, while more distant subjects will require more light up to the maximum output. The flash shooting distance range varies with the aperture, film speed, etc. Flash synchronisation Timing of the flash so it coincides with release of the camera's shutter. There are two types of synchronisation: Front-Curtain Sync, which fires the flash at the start of the exposure, and Rear-Curtain Sync, which fires the flash at the end of the exposure. Flash sync speed Shutter speed at which the entire film frame is exposed when the flash is fired in flash shooting. The F75/F75D's flash sync speed is 1/90 sec. or slower. www.mynikon.com.pl 121 MISCELLANEOUS
