Here’s the rub: since you set the NEF compression type
separately from
Image quality
, it’s easy to forget that you’ve
left it set. For example, you shoot with
Compressed NEF
to
save space on a card during one session. Later you switch the
camera to shoot JPEG. Still later you decide to shoot NEF
again, but want
Uncompressed NEF
. Unless you remember
to cancel compression separately via the menu system, you’ll
still get compressed NEFs when you set your image quality.
If you use the
QUAL
button shortcut to set the
RAW Image
quality
, you’ll never see the compression setting (which is
shown only in the menu system). I understand why Nikon
chose to do it this way—we would have had even more
choices to scroll through in the
Image quality
setting list—
but I can think of better implementations than they chose, and
a compression indicator would have been nice (it doesn’t
even appear on the display that appears when you press the
info
button).
Note that you don’t normally set the
Image size
when you
select
NEF (RAW)
format, as the D300 always records the full
4288 x 2848 image size for NEF files. However, if you elect to
record a JPEG image along with your NEF, you
can
set the
size of the JPEG image that’s recorded using
Image size
(or
the Front Command dial with the
QUAL
button).
Note: If you select any form of compressed NEFs, the file size is
smaller, but the Frames Remaining indicator
does not
necessarily reflect this
. For example,
Lossless
compressed
and
Uncompressed
display the same
number of images remaining! Only
Compressed NEF
displays a different value, though the number it reports is
only a rough guide.
With
Compressed NEF
, you can usually store a handful
more images than it indicates when the card is empty.
For
Lossless compressed
, you can usually store about
1.5x the number the camera indicates (e.g. if the camera
says 24 frames remain, you really have space for about 36).
