EXPOSURE MEASUREMENT-continued
Eyepiece Shutter Operation |
The camera's Photomic finder is fitted with an eyepiece shutter for special unmanned shooting situations (e.g., remote control, automated shooting with motor drive and aperture control unit) requiring protection against the entry of stray light through the viewfinder eyepiece. To close the shutter, simply turn the eyepiece shutter control 60° clockwise; as the shutter closes, the internal LEDs are deactivated and the external "correct exposure" indicator is switched on for metering operation from atop the finder. To set the camera for proper exposure using the external LED indicator, simply adjust the aper- ture ring and/or the
In addition to its use for
When there are substantial brightness differences be- tween the main subject and the background, unimpor- tant bright spots or dark spots can adversely influence the finder reading, and thus the final exposure. To pre- vent under- or overexposure of the main subject under these shooting cond itions, some corrective action must be taken to ensure proper exposure of the main subject. Fortunately, the finder's
To compensate for an excessively bright or dark back- ground, target the main subject in the center of the fo- cusing screen wh ile performing metering; th is action en- sures that the main emphasis of the meter reading will be on the chosen subject. Then, after completing aper- ture and shutter speed adjustments, recompose to the desired picture composition and make the exposure without readjusting the camera controls. For example, when shooting landscapes, it is often advisable to aim the camera slightly downward during exposure measure- ment to eliminate the effects of a bright expanse of sky; without such compensation, the landscape may appear underexposed in the final print. Also, for backlit sub- jects, it may be necessary to move closer to the subject to ensure a proper reading.
