• You cannot select the image quality when using [Sweep Panorama].
• You cannot add DPOF (print order) registration to RAW format images.
• You cannot use [Auto HDR] with [RAW] and [RAW & JPEG] images.
RAW (RAW) File format: RAW (Records using the RAW compression
format.)
This format does not allow you to perform any digital processing
on the images. Select this format to process images on a
computer for professional purposes.
• The image size is fixed to the maximum size. The image size
is not displayed on the LCD monitor.
RAW+J (RAW &
JPEG) File format: RAW (Records using the RAW compression
format.) + JPEG
A RAW image and a JPEG image are created at the same time.
This is suitable when you need two image files, a JPEG for
viewing, and a RAW for editing.
• The image quality is fixed to [Fine] and the image size is fixed
to [L].
FINE (Fine) File format: JPEG
The image is compressed in the JPEG format when recorded.
Since the compression rate of [Standard] is higher than that of
[Fine], the file size of [Standard] is smaller than that of [Fine].
This will allow more files to be recorded on one memory card,
but the image quality will be lower.

RAW images
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 image recorded on this camera. With this software, a RAW image 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.
