Our goal: friendly technology for the iridologist
In this manual you will find essential information to achieve
the best possible iris photographs. Priority was given to
design an intuitive device allowing a deeper understanding
of iris signs in a friendly manner, without technical complica-
tions.
There is more to the IRISO iriscope than its high resolution
and fine detail. The innovative lighting system comes from
photographic expertise into using light to emphasize
perception of textures and display color shades with preci-
sion. The high intensity daylight color balanced LEDs do not
hurt the eyes. They allow taking high quality pictures of
brown eyes, a rare performance even among professional
iriscopes.
The light source varies its angle around the eye, in a way
similar to circling the lamp in a traditional iridology examina-
tion. The resulting photographs are so full of information,
they permit a thorough analysis and future comparisons,
accurately monitoring delicate clinical cases.
The Advanced Techniques section brings professional
photography guidelines to achieve pictures of the best
possible quality.
A valuable accesory is the ingenious Table Stand to prevent
handshake, a negative factor on image sharpness when
shooting handheld. With an IRISO iriscope, your end result
will be a set of detailed images where fibers and textures
clearly show all known signs and beyond.
Welcome to IRISO high definition iris photography!

Self practice
Photographing one’s own iris in front of a
mirror is the best practice for a beginner. The
camera display image reflected in the mirror
allows for a precise framing putting the pupil
right into the center frame, in addition to
getting used to the camera controls.
Poor image sharpness is usually due either
to camera shake pressing the shutter
release, or to eye movement. Shoot
smoothly as described below, and ask the
person to keep both eyes wide open and
stare at a very precise point, like a small
object or at your own right or left eye. With
this last option, moving your own head will
result in slight adjustments of the photo-
graphed iris within the frame, an easier
solution than requesting “move your eye
right or left”.
Firing handheld and shakefree requires
practice. Do not point your finger down on
the camera. Instead lay it alongside the
camera top with the finger tip on the trigger,
and gently bend it to control the pressure.
The movement will be smoother. A first light
pressure will focus, confirmed by a beep
sound and the center rectangle turning
green (yellow is out of focus range). Hold
that pressure while still framing, then gently
press further to shoot.
Comparing different shots with light varia-
tions will be easier if all are equally centered
and framed. The best way to achieve this is
centering the pupil within the focus frame
and always keeping the iriscope level with
both eyes’ axis.

Shooting handheld or with a stand
The iriscope may be used hand-
held or attached to the IRISO
Table Stand, which reduces
hand shake and gives sharper
pictures.
TheTable Stand design owes its
stability to the weight of the
patient resting his arm on the
base plate. That lets him
correctly press the eyepiece
against the face. This direct
contact is essential to place the
eye in the exact spot where the
lights fall on the iris.

Iris shooting sequence
The IRISO lighting system incorporates 4
peripheral LED lights. Those can be com-
bined by opposing pair or individually lit.
Unlike frontal lighting, they do not hurt the
eye or damage the retina and give a better
apreciation of fiber texture and lacunas.
The two basic shots:
vertical and horizontal pairs
The minimum material to shoot of an iris
are those using horizontal and vertical
light pairs. The illumination is uniform
across the eye, and no area remain
unknown due to reflections.
Individual lights for texture and detail
Individual lights enhance fiber details and
moving shadows give important clues:
- tissues raised or sunk get accentuated
under a light crossing at a 90º angle
- the bottom of a lesion is better appreci-
ated if the light path is aligned and deeply
penetrates into it
- some discrete pigmentation spots as well
as textures in the absorption ring are only
perceived under certain light angles
- milky areas show their underlying details
under sideway lighting
These differences are valuable tools to
study aspects easily set aside for a lack of
information, and are the reason for shoot-
ing the full six pictures study of every iris
(two pairs plus four individual lights). This
full record gives access to an endless
source of information to diagnose from or
make future assessments, and accurately
document the evolution of any important
clinical case.
Comparing details in pictures
To ease comparing a same area in differ-
ent pictures, it is recommended to always
center the pupil into the central focusing
rectangle and keep the camera level with
both eyes’ axis. The resulting sequence
will look like the one shown on these
pages
Microscopic detail
The view on the left is an enlargement of
the previous full iris photograph. The
sharpness and detail richness results
from applying the "Advanced Techniques"
described page 16. Those increase
definition down to a microscopic level.
Identifying the patient
Prior to recording the irises, it is advis-
able to photograph the patient’s face, as
much to identify the person as to keep a
record of the general appearance. Doing
it in a cold manner will prevent a typical
portrait smile and also register the mood.
Select the “Auto” mode, slightly zoom the
lens and take the picture of the face.
Remember to set the camera back to “P”
mode to photograph the iris.

Additional technical information
Reviewing pictures
The photographs can be displayed on screen and
zoomed (1) in order to see tissues with more detail.
Options to show the images on a larger screen are to
download the files to a computer with a USB cable
(not supplied), to connect the camera to a TV set
using Canon cable AVC-DC400ST, or to use an
Eye-Fi brand wireless SD memory card to transmit
pictures to a computer or tablet as they are taken.
Check the camera manual for more information.
Downloadable software from Canon detects the
connection to a USB port and automatically down-
loads the pictures to the computer
Resolution and compression (2)
We recommend selecting the larger image sizes, L or
M1, combined with Fine quality compression.
An 8GB card will hold more than 3,000 such images.
Resizing picture for iridology software (3)
The IRISO images produce excellent results in iridol-
ogy programs, although the higher camera resolu-
tions have to be previously downsized. To do so, open
the picture, press "Menu", select "Resize " and
choose M2 (best quality) or S (smallest). This gener-
ates new smaller file appropriate for most software.
Direct printing (4)
The pictures can print directly via USB cable from the
camera to some Canon printers, or other compatible
with PictBridge. Check the camera and your printer
manual.

Advanced techniques
• The following techniques are intended to record
significantly sharper pictures.
- Increase the file parameters
Press the " FUNC.SET " button (1), find the "My
Colors " symbol and change to
Press then the "DISP" Button (2) and increase param-
eters: Contrast +1, Sharpness +2 and Saturation +1
- Small zoom increase
Zooming the lens displays a distance scale on
screen, apply a small zoom up to "2cm - 50cm"
(should focusing get difficult, reduce to "1cm - 50cm")
- Align the camera
A precise parallelism of the camera’s with the eyes’
axis ensures sharpness on the iris from side to side.
- Keep light on high, lower only with sensitive eyes
- Manual instead of Automatic ISO (3), at 100 for
light to medium color, ISO 200 for dark eyes.Caution:
camera may be more sensitive to hand shake.
- Avoid movements
The IRISO Table Stand will eliminates camera shake,
and have the patient look at a specific spot to minimize
eye movements.
- Multiple shots
This technique significantly improves picture sharp-
ness. (4) Press below “FUNC.SET” and select ,
Press “Menu” to program the values "0 sec./ 3 shots".
The option is automatically reset to off and should
be selected at the start of each photo session.
After taking the identical 3 shots in a row, display
them on the camera screen and press the "DISP"
button (5) to show technical file information. A number
of MB will appear. Within identical series, the picture
showing the highest MB count is the sharpest one.
Keep it and delete the other two identical ones with
lower MB.

Maintenance
IRISO Xpert needs very little care to keep up. The
LED’s will last over 10,000 hours (i.e. 120,000 five
minutes photo sessions), the only attentions will be in
changing batteries and cleaning the eyepiece.
Eyepiece preventive care
The rubber eyepiece must be cleaned with alcohol or
a medical desinfectant wipe before or after each use.
At the end of every labored day, it is advised to apply
a siliconized lotion or cream to the rubber eyepiece
and leave it all night. An autopart tire gel or lotion will
work well at sealing and enhancing the rubber, and
will reduce makeup staining. It should be wiped off
with alcohol previous to using.
The rubber eyepiece is user replaceable with care,
contact IRISO for more information.
Troubleshooting
The camera repeatedly fails focusing
- “Macro” mode may not be selected
- zoom out until displaying "1cm - 50cm"
Images do not reach the expected sharpness
- avoid handshake when shooting (use the IRISO
Table Stand)
- have the patient stare at a precise point keeping
both eyes open
- use the self-timer multiple shots technique (p.16)
- refer to all "Advanced Techniques" section (p.16)
Lights reflections surrounded by a halo, picture
looks “milky”
- the front lens is collecting moisture due to cold
weather, cold camera or high humidity in the environ-
ment or coming out of the person’s skin. Proceed
quickly and shortly remove the camera from the face
every so often.
Sclera is too bright showing no detail
- the vertical pair of lights is recommended for sclera
- decrease picture brightness with
One light is failing
- check that the eyepiece cable is fully connected to
the controller box
All eyepiece lights are failing
- check the eyepiece connection to the controller box
- check the light high/low power switch is set in a
correct position
- if battery level LED has turned red, put fresh ones in
I do not find my failure in the list
- contact IRISO to find the solution to your problem.
We will diagnose if the failure is due to the camera or
the adaptation, and propose a solution or agree on
the procedure to follow. The iroscope adaptation is
warranted for one year valid through IRISO, the
camera has its own one-year manufacturer warranty.
