[. . . ] In this case, set a wider aperture on the camera or lens, or move closer to the subject. lD-TTL auto flash mode m Press the MV-1 DATA READER's MODE button until "B" (Auto Aperture flash) appears on the LCD panel. Set the same aperture on the MV-1 DATA READER as set in the D-TTL auto flash mode. If the ready-light blinks after firing, this indicates the light may have been insufficient for correct exposure. In this case, set a wider aperture on the camera or lens, or move closer to the subject. lNon-TTL auto flash mode m Make the necessary settings on the MV-1 DATA READER and camera, and press the h button. If the ready-light blinks after firing, this indicates the light may have been insufficient for correct exposure. In this case, set a wider aperture on the camera or lens, or move closer to the subject. lAuto Aperture flash mode m Make the necessary settings on the MV-1 DATA READER and camera, and press the shutter release button slightly, then press the h button. If the ready-light blinks after firing, this indicates the light may have been insufficient for correct exposure. In this case, set a wider aperture on the camera or lens, or move closer to the subject. lManual flash mode m In manual flash mode, checking the correct exposure cannot be performed by test firing. Calculate the correct flash output level, aperture, and flash shooting distance by referring to "Determining the aperture and flash output level in the Manual mode" (p. 44). 54 Advanced operation Advanced operation In this section advanced information on each function of the MV-1 DATA READER's is provided. Exposure compensation and flash output level Exposure compensation allows you to take well-balanced pictures by intentionally modifying the correct exposure when a subject of extremely high or low reflectivity is included in a picture or when you want to create flash photographs to match your creative preferences. nSome plus compensation may be necessary when the background includes a mirror, white wall, or other highly reflective surface. Likewise, some minus compensation may be required when the background is dark or includes subjects of low reflectivity. If you use both controls, the exposure is modified by the sum total of both compensation values. In this case, the MV-1 DATA READER's LCD panel shows only the compensation value set on the MV-1 DATA READER. Canceling flash output level compensation The flash output level compensation cannot be canceled by turning the MV-1 DATA READER off. To cancel, press the e or f button to set the compensation value back to 0. 0 and make sure the exposure compensation indicator disappears. 58 The flash shooting distance range with zoom lenses having a variable aperture With zoom lenses having a variable aperture, take note of the following before setting the aperture on the MV-1 DATA READER and confirming the flash shooting distance range. Lenses having a variable aperture m There are two maximum aperture values indicated in the lens model name. For example with the AF Zoom-Nikkor 28-105mm f/3. 5-4. 5D IF, the maximum aperture at 28mm is f/3. 5, but decreases to f/4. 5 at 105mm. lReading the aperture on the camera's LCD panel or in the viewfinder Advanced operation m After composing the picture by zooming in or out, read the aperture on the camera's LCD panel or in the viewfinder. Then set the same aperture on the MV-1 DATA READER's LCD panel and confirm the flash shooting distance range. nAperture values are automatically compensated by the camera and appear on the camera's LCD panel or in the viewfinder. The aperture value displayed in the aperturedirect-readout scale as seen in the viewfinder of the Nikon F5 or other cameras is fixed and not automatically compensated. lReading the aperture using the scale on the lens m After zooming in or out to select the appropriate composition, read the aperture using the aperture scale on the lens. Then set the same aperture on the MV-1 DATA READER's LCD panel and confirm the flash shooting distance range. At wideangle zoom settings, read the aperture value at the green index (or line). At telephoto settings, read the aperture value at the yellow index (or dot). At intermediate settings, read the aperture value between the two indexes. lReading the aperture using the camera's aperture dial F-401x/N5005, F-401s/N4004s, F-401/N4004 camera + CPU lens m After zooming in/out to select the desired composition, read the aperture using the camera's aperture dial. [. . . ] Three beeps sound during wireless multiple flash shooting. Cause The aperture or flash output level compensation value set is out of the usable flash shooting distance range. The flash has fired at its maximum output and underexposure may have occurred. Ref. 90 If the built-in wide-flash adapter is broken off accidentally m The wide-flash adapter may be broken off, if it receives a strong impact while set on the flash head. If it becomes broken, visit your nearest authorized Nikon service center for repair. Setting the zoom-head position when the wide-flash adapter is broken off using Custom settings m It is no longer possible to set the zoom-head position to other than 14mm or 17mm. [. . . ]
