Panasonic C-D3100ZM-S - Red-eye reduction; How to Use Red-eye Reduction; Mode Limitations

Red-eye reduction
Use this mode to reduce the possibility of eyes showing up red in
your photo. Just press the Flash mode / SELECT button until the red-
eye reduction symbol appears.
The red-eye effect can occur when using flash for low-light
photography. When the mode is selected and the shutter release
button is pressed, a red-eye reduction lamp lights up, followed by
the release of the shutter with flash. After pressing the shutter release
button, keep the camera still for about 1 second until the Aash fires,
Even when the red-eye reduction mode is used, the red eye effect
may still occur for certain individuals under certain conditions.
This function will only work when it is dark enough for the red eye
effect to present a problem. Thus it may sometimes not operate even
when set,
This mode is not advised for taking quick snapshots due to the
necessary delay involved.
