Because super-fine and RAW data files are so large, the UHS continuous-advance
drive mode cannot be used with these image-quality settings. After capturing five RAW
or three super fine images successively, there will be a a few minutes delay while the
images are being saved to the memory card. The access lamp will glow and the
monitors will be blank during this period.
In the RAW image-quality mode, the image size is set at full and cannot be changed.
The image size will not be displayed on the monitors. The digital zoom, enlarged
playback, data imprinting, and print functions cannot be used.
Unlike the other image-quality modes, RAW image data is unprocessed and requires
image processing before it can be used. To view the RAW data, the DiMAGE Viewer
software is required. This software can reconstruct the image and apply the same
image processing controls as the camera. RAW data is saved as a 12-bit file; the
DiMAGE Viewer software can convert this data into 24-bit or 48-bit TIFF files.
A RAW image is stored with a file header that contains white-balance information,
changes made to contrast, saturation, and color with the Digital Effects Control, any
image processing applied in a subject-program setting, and changes to sharpness. The
changes in camera sensitivity are applied to the RAW data; ISO values can be
manually set to control noise (p. 48).
The camera’s image-processing controls apply the affect of the color modes to the live
image displayed on the monitors, but the stored data may not be influenced by the
setting. The black and white color mode has no effect on the final image; a raw image
taken in the black-and-white color mode can be restored to a color picture. However,
black and white filter effects (p. 77) are not applied to a RAW image. The saturation
difference between the Natural Color and Vivid Color modes is preserved in the RAW
data, but the solarization color mode does not alter the image data. For more on color
modes, see page 98.

Approximate file sizes.
The number of images that can be stored on a memory card is determined by the size
of the card and the file size of the images. The actual file size is determined by the
scene; some subjects can be compressed further than others. The tables below list
approximate file sizes based on average file sizes.
