z 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.

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.
