The SunEye camera needs a few seconds to auto-adjust for lighting after you enter preview mode. When you press snap, hold the SunEye steady until you hear the beep that indicates the shot is complete. After the Skyline is snapped, the SunEye processes the data, and this takes a few seconds before it is ready for the next shot. When taking many Skylines, consider using the NAV button features. For example, after a Skyline is snapped, press the right NAV button to immediately proceed to a new Skyline, or press the left NAV button to erase the previous Skyline and redo it. The center NAV button can be used to SNAP the Skylines.
