Nikon manual Use of Iris Camera MEC-2-CB-D60-N105

6. Turn on the focus light by moving the small slide switch on the battery pack forward.

Focus light is switched on via a small slide switch on the outer top edge of the battery pack.

7. Use the main command dial at the upper rear of the camera for adjusting the aperture.

The aperture dial (situated where the right thumb would be when holding the camera with the right hand) is changed by the thumb; clicking the wheel inboard (to left) decreases aperture number and clicking the wheel outboard (to the right) increases it. Larger aperture values mean smaller aperture diameter -- less light will be allowed in. Images with higher f/numbers will be darker than those taken with lower f/numbers. For 1:1 macro photography, it is a good idea to take a sequence of 3 or so photos, each with an increasing aperture.

Note: If the just-taken image is showing, you must press the picture-taking button slightly (or press the play button) to stop the image playback before adjusting aperture. Aperture will not change if an image is being displayed.
