Anleitung Zusammenfassung
•When a Nikkor lens without a built-in CPU is mounted or no aperture value is displayed in the viewfinder calculate the effective f-number using the above equation after setting the aperture on the lens. 2 Exposure compensation in close-up flash photography In close-up flash photography, it’s recommended to take additional shots with varying exposures to ensure getting the correct exposure. Exposure compensation in TTL Auto Flash “TTL” mode •Make exposure compensation on the camera to match the shooting situation. Refer to your camera’s instruction manual for details on how to make exposure compensation. •When shooting a subject containing highly reflective surfaces, use some plus compensation. When the background is very dark, or the subject is in deep shadow, use some minus compensation. •Normally you can compensate exposures within a range of –2 EV to +1 EV. •When minus compensation is made, the overexposure warning indicator LED may light up. In this case, set a smaller aperture (larger f-number) on the lens, then make minus compensation again. Exposure compensation in Manual “M” mode •Intentionally change the aperture set on the camera or lens aperture ring. •When you want an overexposed picture, set a wider aperture (smaller f-number). For an underexposed picture, use a smaller aperture (larger f-number). Multiple flash operation Optional accessories You can use additional flash units to eliminate harsh shadows cast by the subject on the background or to create special lighting effects not possible with a single flash unit. With the SB-29s, multiple flash shooting—either wireless or using cords—is possible. In both cases, TTL multiple flash with cameras compatible with the TTL auto flash mode as well as Manual multiple flash are possible. For details, refer to your camera, lens, and accessory instruction manuals. Master flash unit and slave flash unit Master flash unit: The flash unit mounted on the camera, the camera’s built-in Speedlight, or the Speedlight connected directly to the camera using a remote cord. Slave flash unit: All other flash units that fire in sync with the master flash unit. Multiple flash operation using a sync or remote cord •SB-11, SB-14, SB-140 and SB-21B Speedlights cannot be used with Nikon F-401/N4004 or F-401s/N4004s cameras. •Use of the SB-50DX and SB-23 as slave flash units using cords is not recommended, because the standby function cannot be canceled. •In multiple flash operation, if the electric current in the synchro circuits exceeds a certain level, you may not be able to take second shot after the first. In this case, disconnect the master flash unit from the camera. This resets the circuits so you can resume shooting. •To prevent the above from happening, take care that the combined total of the coefficients in the table below for all flash units used together does not exceed 20 at 20 °C (68 °F) or 13 at 40 °C (104 °F). •Refer to “Optional accessories” for sync or remote cords. •Read each product’s instruction manual for details on connections. Wireless multiple flash operation •Speedlights suitable for use as slave flash units in wireless multiple flash are ones featuring a wireless slave flash mode or those mounted on the optional Wireless Slave Flash Controller SU-4. •In A (auto) mode, the light sensor on Speedlights so equipped or the one on the SU-4 detects the light from the master flash. Then, the slave flash unit or units start and stop firing in sync with the master Speedlight to produce the correct overall exposure. In M (manual) mode, the slave flash unit or units only start firing in sync with the master flash unit. •These Nikon Speedlights are usable with the SU-4: SB-29s, SB-29, SB-28, SB-28DX, SB-27, SB-26, SB-25, SB-24, SB-23, SB-22s, SB-22, SB-20, SB-18, SB-16B, SB-15 Read the SU-4’s instruction manual for more details. ¦TTL multiple flash operation Connect the master flash unit to the camera directly. Or use the TTL Remote Cord SC-17/SC-24 instead. Connect the master flash unit to the slave flash unit(s). •Use one or more TTL Remote Cords SC-18/SC-19 for direct connection or use these cords in combination with the TTL Multi-Flash Adapter AS-10. •In wireless multiple flash operation, position the slave flash unit and the SU-4 toward the master flash unit, so that light from the master flash unit can reach the light sensor windows. Set each flash unit by considering its direction and distance. •Please note that the brightness of flash illumination is inversely proportional to the square of the distance between the flash unit and the subject when the same Speedlight models are used for both the master and slave flash units. For example, if the flash-to-subject distance is a reference unit of 1, the brightness will be one-half that when the subject is 1.4 times away, and onequarter when the subject is twice as far away. Turn on all flash units and make sure their standby functions are not activated. Set the flash mode on all flash units to TTL. •Set ...
