screen instead of the
viewfinder.

• Aiming at an angle that

axis.
It is best to point the
lens directly at the sub-
ject, and not at an
angle.

1. Reorient the camera

so that light is not shin-
ing directly into lens.

not indicate a problem
or malfunction.

Wait until an image is on
the LCD before perform-
ing a button operation.

Auto play can be used
only when there are two
or more images in cam-
era memory.
