The image compression rate determines the image quality. As the file size of the
uncompressed image will be larger, it is common for a digital camera to compress the
recorded image.

* The data is compressed up to about 60 to 70% compared to an image not compressed. Use this setting
when you want to increase the number of images that can be taken.
• You can also use the Fn (Function) button for operation (page 30).

About RAW files
The RAW format file is the raw data yet to go through any kind of digital processing. A RAW file is
different from a more common file format such as JPEG in that it is the raw material to be processed for
professional purposes. You need the “Image Data Converter SR” software included on the CD-ROM
(supplied) in order to open a RAW file recorded on this camera. With this software, a RAW file can be
opened and converted to a common format, such as JPEG or TIFF, and its white balance, color saturation,
contrast, etc., can be readjusted.

File format: JPEG
The image is compressed in the JPEG format
when recorded. The higher the compression
rate, the smaller the file size. This will allow
more files to be recorded in one memory
card, but the image quality will be lower.
Once the image quality is lowered, it cannot
be restored on a computer afterwards. If you
plan to process or edit the image file later,
consider the image quality carefully when
selecting the setting.
