File Naming; Long Exp. Nr (Long Exposure Noise Reduction) - Nikon D300S User Manual

File Naming

Photographs are saved using file names consisting of "DSC_" or, in
the case of images that use the Adobe RGB color space, "_DSC",
followed by a four-digit number and a three-letter extension
(e.g., "DSC_0001.JPG"). The File naming option is used to select
three letters to replace the "DSC" portion of the file name.
For information on editing file names, see steps 2 and 3 of
"Renaming Shooting Menu Banks" (0 254). Note that the portion
of the name that can be edited is a maximum of three characters
long.
A
Extensions
The following extensions are used: ".NEF" for NEF (RAW) images, ".TIF"
for TIFF (RGB) images, ".JPG" for JPEG images, ".AVI" for movies, and
".NDF" for dust off reference data. In each pair of photographs recorded
at image-quality settings of NEF (RAW)+JPEG, the NEF and JPEG images
have the same file names but different extensions.
Long Exp. NR
(Long Exposure Noise Reduction)
If On is selected, photographs taken at
shutter speeds slower than 8 s will be
processed to reduce noise. The time required
for processing is roughly equal to the current
shutter speed; during processing, "l m"
will blink in the shutter speed/aperture
displays and pictures can not be taken (if the
camera is turned off before processing is complete, the picture will
be saved but noise reduction will not be performed). In
continuous release mode, frame rates will slow and while
photographs are being processed, the capacity of the memory
U
buffer will drop.
