To compensate, use a wider aperture (smaller f-number) in Aperture-Priority Auto or Manual exposure mode or move closer to the subject and shoot again. • Underexposure indication • If the underexposure has occurred with cameras of Group I or Nikon Digital cameras (p. 28, 29), : blinks and the amount of underexposure (0 to -3.0 EV) appears for 3 sec. in the LCD panel, at the same time the ready-lights blink (as mentioned above). • Amount of underexposure appears for approx. 3 sec., then disappears. Pressing the ZOOM button and the - button at the same time makes the amount of underexposure appear again.
