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

(Small),

(Medium 1),

(Medium 2), and

(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).
