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.
