Selecting Image Quality and Size
The image quality and size you select determine the file size of a picture when
stored in the internal memory or on the memory card.
Image Quality
The process of reducing the image file size when storing is called compression.
In this camera, pictures are compressed and recorded as JPEG files. The more a picture
is compressed, the smaller the image file size becomes. As a result, more pictures can
be stored in the internal memory or on the memory card. However, the image quality,
compared with a picture taken with a lower compression ratio, decreases and pictures
cannot be printed at large sizes without a loss of quality.
The less a picture is compressed, the larger the image size becomes. As a result, fewer
pictures can be stored in the internal memory or on the memory card. However, less
compression increases the image quality.
Image Size
Larger pictures create larger image files and are suitable for printing in large size. How-
ever, fewer pictures can be stored in the internal memory or on the memory card.
Smaller pictures create smaller image files and are more suitable for transmission by e-
mail or for use on web pages.
When printed in larger sizes, however, small images will look rough and uneven in ap-
pearance.
