Flash output level compensation. Available in TTL auto flash mode, Auto Aperture flash and Distance-priority manual flash operations. In the TTL auto flash mode or Auto Aperture flash operation, flash output level compensation is only available with cameras compatible with CLS, digital SLRs not compatible with CLS, and cameras in Groups I to III. Flash output level compensation cannot be made on the SB If you use both controls, the exposure is modified by the sum total of both compensation values.
Exposure compensation on the SB can be performed in these ways:. Exposure compensation beyond the usable Nikon sb800 инструкция sensitivity range cannot be performed. Making exposure compensation in Non-TTL auto flash and Manual flash operations Exposure compensation is performed by intentionally modifying the correct aperture. In the Non-TTL auto flash mode, the correct exposure can be obtained when the same aperture is set on the camera as that set on the SB Therefore, to make exposure compensation, vary the aperture set on the camera while retaining the aperture set on the SB or vice versa.
If the ISO sensitivity is correctly set, the flash shooting distance appears on the LCD panel, matching the flash output level and aperture as set Note: Many other Nikon Speedlight uses this. The CLS-ready series changes it to With cameras in Groups III to VII 8 Set the shutter speed. Use the equation to determine the shutter speed Nikon sb800 инструкция use that shutter speed or one slower.
This feature is available with cameras providing rear-curtain sync. Since slow shutter speeds are usually used, use a tripod to prevent camera shake. This function does not operate in Repeating flash operation. In multiple flash, the master flash unit can be set to either front-curtain or rear-curtain sync flash. However, the remote units cannot be set to rear-curtain sync flash.
With fresh batteries of the same type in both the SB and optional Nikon SD-8A or Power Bracket Unit SK Exposure compensation and flash output level Exposure compensation allows you to take well-balanced pictures by intentionally modifying the flash exposure. This is useful when a subject of extremely high or low reflectivity is included in the scene or when you want to create flash Nikon sb800 инструкция to match your creative preferences. Some plus compensation may be necessary when the background includes a mirror, white wall, or Nikon sb800 инструкция highly reflective surface.
Rear-curtain sync In normal flash photography, when shooting fast-moving subjects at slow shutter speeds, unnatural-looking pictures can occur, because the subject frozen by the flash appears behind or within the blurred movement see Nikon sb800 инструкция below right.
Canceling flash output level compensation The flash output level compensation cannot be canceled by turning the SB off. Slow-sync flash The flash is controlled at a slow shutter speed to obtain the correct exposure for both the main subject and background in low-light situations or at night. This mode is available with cameras providing slow-sync. You cannot set the slow-sync function on the SB directly, but must set it on the camera. Note: Since slow shutter speeds are normally used, use of a tripod is recommended to prevent camera shake.
Referring to the table below, set the flash output level, the frequency, and the number of repeating flashes separately for each picture. The flash output level is set, then the frequency display is highlighted. Finally set this aperture on the SB You cannot set the aperture on the SB directly.
Setting the flash output level, the frequency Hzand the number of Nikon sb800 инструкция flashes per frame a Frequency Hz represents the number of times the flash fires per second The actual number of repeating flashes per frame becomes lower than the one set as the shutter speed increases or the number of flashes per second decreases, because the Speedlight fires during a single exposure.
Operation: 1 Press the SEL button Nikon sb800 инструкция highlight the Flash output level compensation value. The highlighted flash output level compensation value returns to normal display. The last highlighted number is the one automatically set.

Likewise, some minus compensation may be required when the background is dark or includes subjects of low reflectivity. Making exposure compensation for both the main subject and background, the main subject only without affecting the background, or the background only without affecting the main subject are possible, depending on the flash shooting situation.
When you press the. Repeating flash In Repeating flash operation, the SB fires repeatedly Nikon sb800 инструкция a single exposure, creating stroboscopic multiple-exposure effects. This operation is useful Nikon sb800 инструкция shooting fast-moving subjects. In this operation, appears on the LCD panel. Be sure to use fresh or fully charged batteries and allow enough time for the flash to recycle between each repeating flash session. Maximum number of repeating flashes per frame:.
Rear-curtain flash sync creates a picture in which the blur of a moving subject for example, the taillights of a car appears Nikon sb800 инструкция the subject and not in front. Note: In front-curtain sync, the flash fires immediately after the front curtain opens completely; in rear-curtain sync, the flash fires just before the rear curtain starts to close.
In the Manual flash mode, calculate the proper aperture for the correct exposure from the guide number and the shooting distance. Then, use a larger or smaller aperture on the camera to make exposure compensation. As a basic guide, set a wider aperture Nikon sb800 инструкция the camera or lens to make the main subject brighter or a smaller aperture to make it darker. This compensation can only be performed with cameras compatible with CLS, digital SLRs not compatible with CLS, and cameras in Nikon sb800 инструкция I to III.
Or you can set the shutter speed to B bulb to accommodate any number of repeating flashes. WARNING: Do not exceed the maximum number of continuous firings You should allow the SB to cool off for at least 10 minutes after the maximum number of continuous firings Nikon sb800 инструкция performed as shown in the table below left. Synchronization during continuous flash shooting It is possible to take up to the number of frames during continuous shooting as shown in the table below. However, if the continuous firings exceed the maximum numbers as shown in the table above, you should allow the SB to cool off for at least 10 minutes.
Available with cameras having Red-Eye reduction control. You cannot set Red-Eye reduction on the SB directly, but must set it on the camera. Red-Eye reduction with slow-sync flash mode In this mode, Red-Eye reduction is combined with slow sync. This mode is available with cameras having Nikon sb800 инструкция reduction with slow-sync. You cannot set this mode on the SB directly, but must set it on the camera. Since slow shutter speeds are normally used, use of a tripod is recommended to prevent camera shake.
