Underexposure indicator
Amount of underexposure
• If the SB-28’s ready-light and the underexposure indicator blink for
approx. 3 seconds after shooting, the flash has fired at its maximum
output, indicating the light was insufficient for correct exposure. The
amount of underexposure (for example, –1.0 to –3.0) also appears on the
SB-28's LCD panel. To compensate, use a wider aperture or move closer
to the subject and reshoot.
• You can recall the amount of underexposure last shown on the LCD panel
by pressing the
