NEF (RAW) Images
A
NEF (RAW) images can be viewed on the camera or using software
such as ViewNX 2 or Capture NX-D (ViewNX 2 can be installed from the
supplied installer CD, while Capture NX-D can be downloaded from a
link in the ViewNX 2 installer; 0 262, 268). Note that the option
selected for image size does not affect the size of NEF (RAW) images;
when viewed on a computer, NEF (RAW) images have the dimensions
given for large (#-size) images in the table on page 118. JPEG copies
of NEF (RAW) images can be created using the NEF (RAW) processing
option in the retouch menu (0 406).
NEF+JPEG
A
When photographs taken at settings of NEF (RAW) + JPEG are viewed
on the camera with only one memory card inserted, only the JPEG
image will be displayed. If both copies are recorded to the same
memory card, both copies will be erased when the photo is deleted. If
the JPEG copy is recorded to a separate memory card using the Role
played by card in Slot 2 > RAW Slot 1—JPEG Slot 2 option, deleting
the JPEG copy will not delete the NEF (RAW) image.
A The Photo Shooting Menu
Image quality can also be adjusted using the Image quality option in
the photo shooting menu (0 310).
