The camera adjusts ISO sensitivity in response to
lighting conditions. ISO sensitivity is adjusted in
the range given in brackets; choose larger ranges
for increased sensitivity when lighting is poor,
smaller ranges to reduce noise (randomly-spaced

ISO sensitivity is fixed at the selected value. If 6400
(NR) or 12800 (NR) is selected, the camera will take

create a single image processed to reduce the
noise that occurs at high sensitivities.

or NEF (RAW) + JPEG fine is selected for image quality, the picture will
be recorded as a fine-quality JPEG image. Only one shot will be taken if
