The Nikon F2SB Photomic camera offers the serious photographer the ultimate in quality, performance, convenience and versatility. At the same time, it is engineered to take the guesswork out of photography with automatic features anyone can learn to use in minutes. [. . . ] As long as the fingerguard remains set to "T, " the shutter will remain open. When returning the fingerguard to the normal center position to close the shutter, be careful not to move or shake the camera, as a blurred image may result.
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 aperture ring and/or the shutter-speed selector until the LED just glows; once the LED comes on, the camera is set for correct exposure. In addition to its use for low-light metering or for unmanned photography, the eyepiece shutter comes in handy to ensure correct exposure measurement in critical shooting situations (e. g. , photomicrography) or for protection against the entry of bright light into the viewfinder during daylight shooting.
High-Contrast Lighting Situations
When there are substantial brightness differences between the main subject and the background, unimportant bright spots or dark spots can adversely influence the finder reading, and thus the final exposure. To prevent 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 center-weighted TTL metering action simplifies adjustments, making for qu icker camera operation and more accurate final resu Its. To compensate for an excessively bright or dark background, target the main subject in the center of the focusing screen wh ile performing metering; th is action ensures that the main emphasis of the meter reading will be on the chosen subject. Then, after completing aperture 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 measurement 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 subjects, it may be necessary to move closer to the subject to ensure a proper reading.

• Metering with a bright area in the center will cause underexposure of the main subject.
• For correct exposure, f irst measure the main subject; then, recompose and shoot.
STOP-DOWN EXPOSURE MEASUREMENT
With some Nikkor lenses, full-aperture exposure measurement is not possible, either because the lens has no automatic diaphragm, or because the lens does not couple with the finder's meter; with certain accessories, too, lens/finder coupling is not possible, thus, preventing fullaperture measurement. However, the camera's Photomic meter can still be used for exposure measurement via the stop-down method. Before mounting the lens (or accessory) on the camera body, push the meter coupling pin up into the finder with a coin or similar object; when set, the number "5. 6" will appear in the finder's maximum aperture indicator. After setting the finder, mount the lens or lens/accessory combination on the camera, switch on the meter by moving the film-advance lever to the standoff position, and then set the controls for correct exposure as follows: For fixed-aperture lenses, such as Reflex-N ikkor lenses, simply adjust the shutter-speed selector until the center LED indicator comes on. For convenience, shutter speeds can be set at intermediate settings in the 1/80 sec. If the meter indicates con tinuous overexposure, use a neutral density filter or slower film. If continuous underexposure is indicated, suppleme" ntary lighting or a faster film is necessary. This technique is also suitable for photography using a telescope or microscope"

EXPOSURE COMPENSATION ADJUSTMENTS
Adjustments for Focusing Screens Light transmission properties vary somewhat with focusing screen type, thus occasionally requiring exposure correction to compensate for the combined effects of the lens/screen combination in use. [. . . ] • = Acceptable Slight vignetting or moire phenomenon (in the case of the microprism) affects the screen image. • = Acceptable Incompatible with any lens having a maximum aperture larger than f/2. 8 since thi s decreases the efficiency and accuracy of the screen rangefinder. The in-focus image in the central spot may prove to be slightly out of focus on film. Focus on the surrounding matte area .
