may change often while shooting, this is a good place to
summarize the choices and the method of setting them.
The D300 supports five basic levels of image quality (plus you
can record RAW and JPEG qualities simultaneously:
RAW
(NEF) Images are not demosaiced and do not
have camera data applied to them; you’re saving
the 12-bit or 14-bit sensor data and a list of
camera settings, not a finished image (though a
finished
JPEG basic
thumbnail
is
saved in the
file). The result can be saved with either no
compression or one of two forms of compression
(lossless and visually lossless). The highest
quality image the D300 can capture would be a
14-bit NEF (that isn’t compressed using the
visually lossless scheme).
TIFF
(TIFF) Images are demosaiced by the camera,
camera controls are applied, data is reduced to 8
bits, and the result is stored as a TIFF file. This is
the highest quality image the D300 can produce
internally (RAW requires you to convert the
image externally).
fine
(JPEG) Images are demosaiced by the camera,
camera controls are applied, data is reduced to 8
bits, and the result compressed at a ratio of
about 1:4 and stored as JPEG files. Compression
artifacts are present, but generally not visible.
normal
(JPEG) Images are demosaiced by the camera,
camera controls are applied, data is reduced to 8
bits, and compressed at a ratio of about 1:8 and
stored as JPEG files. Compression artifacts are
present, and may be visible on close
examination (especially if sharpening is used or
you’re using a high ISO value).
