Preparing the Iris Camera for Use – Flex-Lighting
1. Open Camera Carry Case by lifting up each latch.
2. Remove the camera from the foam padding and set down.
3. Lift Illuminator out of foam-padded case

4. Remove lens cap and turn the camera on. Mode dial is set to A=Aperture priority
5. Pop up the built-in flash by pressing button on left side
6. Place illuminator onto lens at the 9:00 position:

7. Rotate Illuminator until it snaps into place at 12:00 position:
8. Press focus light power switch:
9. Your camera is now ready to take iris pictures. When complete with the photography, reverse these steps
to put the camera away.
10. The Side-Lighting illuminator has a shutter that
controls which side the flash illumination goes to.
For photographing the right iris, use the Left
Channel Open position (lever to the left); for
photographing the left iris, use the Right
Channel Open position (lever to right):

11. For “flat” or uniform illumination, use the Both Channels Open position. This is setting is when the
lever is all the way to the left or the right:

12. Use the main command dial at the upper rear of the camera for adjusting the aperture.
The Main Command Dial is operated with the right thumb and is used to adjust aperture. Normally, the best
practice is to take 3 or 4 pictures of each iris, each picture shot with a different consecutive aperture.

13. Note: for general photography, use the enclosed Zoom lens (18-55mm VR) instead (VR=Vibration
Reduction). You may also use any Nikon AF-S or AF-I autofocus lens. Older lenses will not work with
the D60 since it does not include a motor drive; only the newer Nikon AF-S and AF-I lenses have a built-
in motor drive for focusing. You can use any older lens but the auto-focus will not operate.
14. For general photography using the included zoom lens, switch the top Mode dial to AUTO:
15. When you return to iris photography, switch the top Mode dial back to A (A=Aperture Priority).
16. IMPORTANT: Adjust the Eyepiece Dioptric setting. (Initial Setup Only) This is a small slide switch
to the right of the viewfinder that can go up or down through 6 positions (some cameras such as the
D300, have a rotating wheel), and is designed to match the viewfinder optics to your vision. When this is
set: if you see the subject in focus, the camera sees it in focus. If you normally wear corrective lenses,
always wear them when taking a picture. To make this adjustment for your eye:
1. move the switch to one end of the range (top-most or
bottom-most position)
2. look through the viewfinder at a bright surface (such
as a white wall) that is in the distance (this white
surface should appear blurry)
3. while viewing through the viewfinder, move the
switch up or down through the range of 6 positions
until you can see the black bracket marks in the
viewfinder with maximum clarity and focus
4. note the optimal position of this switch for your
vision, and always use this setting. Once you set it fo
r
your eye’s vision, you do not need to change it. If
someone else uses the camera, they need to find the
correct setting for their vision (and when you resume
using the camera, you need to return this switch to th
e
setting you found for your vision).

How To Take Perfect Iris Pictures
1. Be sure the client is comfortably seated and relaxed.
2. If a chinrest is not used, have the client open their own lids by putting the index finger touching the
thumb up to the closed eye (using the arm on the same side of the eye being photographed), and then
separating the index finger and thumb while holding them against the upper and lower lids
respectively. Often this method is helped by having the elbow of this arm on a table.
The client covers the eye not being photographed with one hand and separates the lids with the other.
3. Have the client place the free hand (opposite of the iris side being photographed) over the opposite
eye so as to prevent looking through it. Due to the fact that people have eye dominance (preferring to
use one eye more than the other), it is important to have the client only looking through the eye being
photographed, and looking straight into the camera lens. If people do not cover the opposite eye, they
tend to look around the room with the uncovered eye, causing the eye being photographed to wander.
Often it is helpful to have the client spread apart the eyelids with the index finger and thumb.
4. The client will see a small reflection of their eye in the camera lens, and may be guided to observe this
in order to maintain correct positioning. Ask the client to observe the reflection of their eye in the
camera lens. This will ensure the client's eye is lined up with the camera. Often it is helpful to have
the client spread apart the eyelids with the index finger and thumb.An alternative method (if lid
retraction is not needed) is to have the client put the chin on the palm with the elbow on the table. For
the right iris picture, the right arm is used for support this way, and for the left iris picture, it is
reversed.

5. If a chinrest is used, adjust the height so the center of the iris is about 1” (25mm) below the bottom of
the forehead rest.
When a chinrest is used, lid retraction can be accomplished using two 6” cotton swabs in one hand to separate lids.
6. Bring the camera (with focusing light switched on) into alignment with the center of the iris by
panning in from the lateral side. For handheld photography, it is best for the photographer to have
both elbows on the table and the left hand supporting the lens. If a table is not available, the
photographer can brace the camera with both elbows pressing on anterior ribs.
7. When pointing the camera (with the focus light on) at your client's eye, be conservative about
exposing the client to the focus light. One wants to get nearly in position first with the light shining
just past the client’s face temporal to the eye or above it, pointing at the forehead, at the approximate
range. The eye camera will focus at 3” away from the front illumination cone.
8. With one or both elbows on the table, rock toward or away from the client's eye (fractions of an inch
here) until the image is sharp in the view finder. Focus on the collarette. You can normally get good
camera stability with just one elbow on the table.
9. After taking a photo, the image will play back on the screen for 1 minute (this setting can be changed).
Before changing the aperture, press the shutter release (picture-taking button) halfway lightly to
discontinue the image playback; the aperture wheel (main command dial in A mode) can then be
rotated to go to the next aperture.

10. Always take all the right eye pics first then all the left eye pics. If you take scleral pics, start with the
iris of that eye, followed by the four quadrants of the sclera (normally Left, Right, Upper, Lower).
11. Adjust the camera position until the pupil of the iris is centered on the viewfinder. With this type of
1:1+ photography, focus is accomplished by moving the camera toward or away from the subject.
12. Adjust focus until the image is sharp around the collarette at the four cardinal points.
13. Take picture.
14. Check exposure. The image may appear differently on the monitor than the LCD viewer.
15. Use exposure bracketing by Aperture.Normally, it is best to take a sequence of images of each eye,
and bracket the exposure by using a range of aperture values. Typically for a blue iris the range would
by 29, 32, 36; for a brown iris 20, 22, 25. Use increasing numeric aperture numbers for the right eye,
then the same sequence but in decreasing order for the left iris.
16. To increase the exposure (with the Nikon D-60), adjust the Aperture using the main (rear) Command
dial. 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. The aperture will only change when the playback is
stopped.
For brown irises, the image should be overexposed to bring
out the low-contrast detail.
For Blue iris use aperture 29, 32, 36, 40, 45, or 51
For Brown iris use aperture 18, 20, 22, 25, 29, or 32
The aperture dial is operated with the
right thumb. You must discontinue
image playback first (by pressing the
picture-taking button lightly). Rotation
to the right (“outboard”) will increase
the aperture number (less light);
rotation to the left (“inboard”) will
decrease the aperture. To bracket your
exposure, take the right eye (first) with
apertures ranging upwards across 3 or
4 settings, then photograph the left eye
with the aperture ranging downwards
through the same settings.
