About RAW images
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.
• Recording a RAW image entails the following limitation.
– The RAW image cannot be printed using a DPOF (print) designated printer or a
PictBridge compliant printer.
• You cannot verify the effects of D-Range Optimizer other than those of
(Standard) if you play back and enlarge an image recorded in RAW format.
For details, see page 79.
