10 NIKON D5000: FROM SNAPSHOTS TO GREAT SHOTS
SETTING THE ISO
1. Press the i button on the back of the
camera to activate the cursor in the
information screen.
2. Use the Multi-selector to highlight
the ISO Sensitivity and press the OK
button (A).
3. In the option screen, select the appro-
priate ISO for the level of light you are
shooting in and press the OK button to
lock in the change (B).
■
You should know that the Auto ISO option
is only enabled as a default when using
one of the automatic scene modes. When
using one of the professional modes (M,
A, S, and P; we’ll discuss these in Chapter
4), the Auto ISO feature will be automati-
cally turned off. If you wish to use Auto ISO in one of these modes, you must activate
it and set the auto parameters in the shooting menu. If you plan on shooting with
the Auto mode, you cannot turn off the Auto ISO option at all.
NOISE
Noise is the enemy of digital photography, but it has nothing to do with the loudness of
your camera operation. It is a term that refers to the electronic artifacts that appear as
speckles in your image. They generally appear in darker shadow areas and are a result
of the camera trying to amplify the signal to produce visible information. The more the
image needs to be amplifi ed—e.g., raising the sensitivity through higher ISOs—the greater
the amount of noise there will be.
