Controlling File Size: Selecting Image Quality and Size
The size of the files, and with it the number of images that can be recorded on
the memory or the memory card, depends on the size and quality of the images.
Before shooting, choose an image quality and size according to how you plan to
use the picture.
X Image Quality
The process of reducing the file size of a picture when storing it is called compres-
sion. In this camera, pictures are compressed and recorded as JPEG files.
The more a picture is compressed, the smaller the picture size becomes and the
larger the number of pictures that can be stored in memory or on a memory card.
However, the quality of the image is degraded and the reproducibility of the im-
age’s fine areas is reduced.
The less a picture is compressed, the larger the picture size becomes and the
smaller the number of pictures that can be stored in memory or on a memory
card. However, it maintains the presentation of the image’s fine areas and increas-
es the image quality.
Select from the following three options.
b Image Size
Smaller images create smaller files suitable for transmission by e-mail or for use in
When printed in larger sizes, however, small images will be rough and uneven in
appearance. The size of images when printed depends on the printer resolution:
the higher the resolution, the smaller the final print size.
Fine image quality, suitable for enlargements or
high quality prints. File size reduced to roughly
1/4 of its original size.
Normal image quality, suited to most applica-
tions. File size reduced to roughly 1/8 of its origi-
Basic image quality, suitable for pictures that will
be distributed by e-mail or used in web pages. File
size reduced to roughly 1/16 of its original size.
