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.

' Q "
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 IPEG 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 IPEG or TIFF, and its white balance, color saturation,
contrast, etc., can be readjusted.
