This is a good way to adjust ISO sensitivity quickly. This is
also the easiest method to change the camera’s ISO sensitivity
setting, although it doesn’t involve the Shooting Menu, which
we are now examining.
Here are the steps you’ll use to manually adjust the camera’s
ISO sensitivity:
1. Hold down the ISO button above the Release mode dial.
2. Rotate the rear Main command dial counter-clockwise to
increase ISO sensitivity or clockwise to decrease
sensitivity. The ISO sensitivity number will show on the
Control panel and in the Viewfinder.
Setting the ISO Sensitivity Settings
You can also use Shooting Menu > ISO sensitivity settings to
change the camera’s ISO sensitivity. Figure 3-49 shows the
three screens used select your favorite ISO sensitivity for the
circumstances in which you find yourself.
Notice in image 3 of Figure 3-49 that you have a scrollable
list of ISO sensitivity settings, from Lo 1 (~100 ISO) to Hi 1
(~6400 ISO). The “normal” ISO range for the D300(S) is ISO
200 to 3200. Select your needed ISO sensitivity from the list
of available ISO sensitivity settings.
Here are the screens and steps to select an ISO sensitivity
setting (see Figure 3-49):
