Changing the Resolutionand Compression
You can change the resolution and compression (exclud-
ing movies) settings to suit the purpose of the image you
are about to shoot. The resolution gets higher in the order
S (Small), M (Medium), and L (Large). Use a higher
resolution if you wish to make a large print. Conversely,
use a lower resolution if you wish to print on small
objects, such as labels, to send images electronically, or
to fit more images on a CF card.
The compression gets higher in the order (Superfine),
(Fine) and (Normal). Select (Superfine) for a higher
quality image, or (Normal) if you wish to fit more images
on a CF card. The (Fine) setting provides adequate
quality for standard shots.
