Shooting - Selecting Particular Effects 61
Camera settings such as image resolution and compression, shutter speed and
aperture can be freely changed for shooting.
• Please see Auto Mode (p. 44) for shooting procedures once you have
changed a setting.
Changing the Resolution and Compression
You can change the resolution and compression (excluding movies) settings to suit
the purpose of the image you are about to shoot. The resolution gets higher in the
order
S
(Small),
M1
(Medium 1),
M2
(Medium 2), 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. To record the CCD output without compression, select the RAW file format
(p. 64).
