For the Canon 40D Digital Clinical Camera System - Canon MR-14EX
Congratulations on your purchase of the Canon 40D Digital Camera.Your camera has been completely assembled, tested and is
ready to start taking clinical photos. The rechargeable battery pack is partially charged and installed in your camera body. The
instructions listed below show you the camera settings that work best for macro photography. If you use the camera for recreational
photography, use these instructions to return the camera to the proper clinical settings. Consult the Canon instruction book for
details on all other camera and flash functions.
The memory card has been installed in the camera and formatted. As
shown above, the memory card slot is on the side of the camera body.
Your camera has been set to the Large/Fine mode (10.1 megapixel
resolution/Fine JPG mode). At this setting, you can fit approximately 300
images on a 1GB card. You can change this mode in the camera’s menu.
You can choose MED (5.3 megapixel), SMALL (2.5 megapixel) or RAW in
the camera menu.You can also choose RAW+JPG and you will get two
files - a processed JPG image and a RAW file of that image.
Canon has added a new feature to the 40D - CAMERA USER SETTINGS. There are three user settings
available on the MODE DIAL (C1, C2, & C3). The user settings allow you to combine a group of
camera settings and assign them to one of the three modes on the camera’s mode dial.
This allows us to simplify your use of the camera for clinical photos.We have pre-programmed all
of the settings needed for closeups in the C1 mode and the settings for portrait views in the
C2 mode. Simply turn the dial to C1 for closeups, focus and shoot.Turn the dial to C2 for portraits,
focus and shoot. Its that easy!
Please see page 3 of these instructions for more info about the camera user settings (C1,C2, C3).
Press the ISO button and set the ISO to 100.
Turn on the flash and the camera body. When the PILOT
(ready) LIGHT illuminates on the flash power pack, the
shutter speed will be automatically set to 1/250 second.
Set your f-stop by turning the MAIN DIAL on the top of
the camera body (see photo above).
For closeup shots, use C1 on the Mode Dial (f22)
For portrait shots, use C2 on the Mode Dial (f5.6)

For properly exposed clinical photos, the 40D must
be set to increase the exposure by 1 f-stop.This is
set through the EXPOSURE COMPENSATION BUTTON
(shown above). Press the button and then turn the
QUICK CONTROL DIAL (shown below) to set the
exposure compensation at +1 (as shown). Be sure
to reset this setting to 0 if you are using the camera
recreationally.
The QUICK CONTROL DIAL (QC) is used to adjust
settings on the camera. When you are in PLAY
mode, the QC Dial allows you to view all of the
images on the memory card. When you access the
camera settings through the MENU button (see
below), the QC DIAL allows you to scroll through
the menu choices. Press the SET button to choose
menu options.

For proper color, the White Balance (WB) must be set to the proper setting.
Press the WB button (shown at left) and turn the QUICK CONTROL DIAL
and you will see the choices change on the left side of the LCD display on
the top of the camera. Choose the "K" symbol.
This is called the KELVIN (or color balance) white balance setting.This
setting allows you to adjust the image color in very fine degrees (100°K
increments - from 2500°K to 10,000°K).This feature offers you the ability
to fine tune the color for your lighting
environment.
To set the KELVIN setting, press the MENU
button navigate to the 2nd menu tab. Scroll
down to the WHITE BALANCE option (as
shown). Press the SET button to choose the
WHITE BALANCE option. Using the MAIN
DIAL (see page 1), you can change the color
temperature in 100°K increments. We have set
your camera to 5000°K. Under the standard
fluorescent lights in our office, this setting gave
us images with very realistic color. Your office
lighting may be different or you may prefer a
slightly warmer or cooler color balance.
For a Warmer color balance: set the color temp to a higher number
For a Cooler color balance: set the color temp to a lower number
If you use the camera outside the office or for non-dental photos, set the
white balance to the AWB (auto white balance) setting. In this setting, the
camera will adjust for whatever type of lighting you are shooting in.
Canon has added a useful mode to the
40D called WHITE BALANCE SHIFT. In the
2nd MENU, choose WB SHIFT/BKT and
the grid shown appears on the LCD
screen. Using the MULTI CONTROLLER
(shown left), you can influence the image
color towards any of the four colors
shown: green, blue, magenta or amber.
The MULTI CONTROLLER allows you 8 directions of movement. Position
the white square within the grid to change your image color. Position the
white square back in the center of the grid to reset the WB SHIFT.

Canon has added a new feature to the 40D - CAMERA USER
SETTINGS. There are three user settings available on the MODE
DIAL (C1, C2, & C3). The user settings allow you to combine a
group of camera settings and assign them to one of the three
modes on the camera’s mode dial.
We have pre-programmed the C1 mode with the necessary settings for closeups and C2 for portraits. This leaves all of the
other modes open for other photographic uses and it helps to prevent members of your staff from accidentally changing
the dental settings. If someone does change something, you simply turn the mode dial to any other selection, wait for a cou-
ple of seconds and turn it back to C1 (or C2). All of the pre-programmed settings will return.
If you wish to change any of the settings in C1 or C2 permanently, you need to go to MENU 7 (shown above), select CAMERA
USER SETTING, select REGISTER and then choose which of the USER MODES you wish to save the setting to.
When initially setting a custom mode (or if you would like to reset the camera), the camera should be in the Av Mode.Turn
the MODE DIAL to Av, set the settings shown on the previous pages of these instructions. When finished, press the MENU
button, navigate to menu #7 and choose CAMERA USER SETTINGS. Choose REGISTER and then select C1 (or C2 or C3). Press
the MENU button 3 times to back out of the menu.Turn the MODE DIAL to a custom setting and verify your settings.

You can use your camera in the AF (autofocus) mode or MF
(manual focus) mode (A). In MF mode, you can set the lens to
a given magnification for repeatable image sizing by turning
the focusing grip (B). Once you have set the magnification
(C- orange numbers), look through the camera viewfinder
and move towards and away from the subject until you see
sharp focus.
If you decide to use the AF mode, look through the viewfinder
and halfway press the shutter button. The camera will attempt
to focus on your subject. Be aware that areas of low contrast
or shooting in low light may make it difficult for the camera
to lock in the focus.

Live View is a new feature that Canon has added to the 40D. It allows the LCD screen to be used as a viewfinder. While this
may sound useful for clinical photography, it does have some limitations.
Live View is primarily as manual focus feature only (more on this in a moment). This means that for clinical use, you would
set the lens magnification for the view you wish to photograph and activate Live View by pressing the SET button.Then,
while viewing the image on the LCD screen, move the camera towards and away from the subject until you see the image
in focus and shoot.
There is a way to use Live View with autofocus, but it is designed for static subjects and is really of no use for clinical
photography. To use Live View in autofocus mode, first make sure the lens is set to AF. Next, activate Live View by pressing
the SET button as explained above. Locate the AF-ON button (upper right corner of the back of the camera - near where
your thumb rests when taking a photo). Hold the camera very steady and press and hold the AF-ON button until the
camera beeps (the LCD screen will turn black during this step). Release the AF-On button while keeping the camera steady.
If the image is in focus, shoot.
Live View is a nice feature when shooting on a tripod (studio,
portrait, astrophotography), but it does not lend itself to
clinical photography very well. It is up to you as to whether it fits
your needs.
Shown at right are the menu screens that allow you to activate
Live View on your camera. If you purchased your camera from
PhotoMed, this setting is already activated.
Shown below are our recommendations for the 40D menus. Use the MULTI CONTROLLER (see page 2) to move “sideways”
across the menu tabs and to navigate up and down through the menus. Use the SET button to choose a menu selection and
press the MENU button to go “backwards”. The Custom Function settings from menu#8 are shown below.

We suggest that you become familiar with the layout of the LCD displays. Before taking a photograph, glance at the displays and
ensure that the shutter speed, f-stop and flash mode are correct. If you get in the habit of doing this, you will catch any instances
where a button gets pushed or the MAIN DIAL gets turned accidentally before you take the photo at an incorrect setting.Thank
you again for your purchase of the Canon 40D Digital Clinical System.
If you have any questions, please call one of our technical experts at 818-908-5369.

40D - Canon MR-14EX
Canon’s E-TTL flash metering system is a
terrific convenience when shooting the
wide range of dental photos:
posterior vs. anterior, direct vs. mirror
shots.The camera determines how much
light is necessary and controls the flash
output for a proper exposure.
Before and After (B&A) bleaching photos are the exception to
the rule.We obviously want to show the dramatic change in
the brightness of the smile, but if we use the camera controlled
flash system, the Before photo will be brighter than it actually
is and the After photo will not show the level of brightness
achieved. This is due to the camera detecting that the Before
photo needed more light and the After photo was reflecting
quite a bit more light.
The only way to show the true degree of bleaching in B&A
photos is to set the camera to manual mode and use pre-
determined settings to ensure that the camera cannot attempt
to control the exposure. Listed below are the steps necessary.
Once you have gone through the steps, you can easily set your
camera in a matter of seconds.
1. Set your camera to the M mode (see photo). Set the shutter
speed to 250 by turning the MAIN DIAL (see photo page 1).
2. Set the flash in the M mode by pressing the MODE button
on the back of the flash power pack (see photo page 1).
3. Set the lens to MF (see photo page 3). Decide which lens
magnification you would like to use for your anterior shots
(see photo page 3). For the 40D, a lens magnification of 1:3 is
a good starting point. Once you decide which magnification
works for you, always use this setting.This ensures that the
distance to the patient is always the same and the exposure
will be the same.
Now, the testing begins:
4. Set the f-stop (see photo page 1) to 32 by turning the QUICK
CONTROL DIAL (see photo page 2).
5. Put your eye to the camera viewfinder and move towards and
away from your subject until you see the image in sharp focus.
Press the SHUTTER BUTTON to take a photo. Evaluate the image
on your computer and compare the image to your subject.
If the image is TOO BRIGHT: press the SEL button on the back
of the flash power pack and then press the - (minus) button to
change the power to 1/2. Repeat the photo and evaluate. Keep
lowering the power until the exposure is correct.
If the image is TOO DARK: turn the QUICK CONTROL DIAL to
change the f-stop to a lower number (i.e., from 32 to 29).
Repeat the shot and evaluate. Keep opening the f-stop (to a
lower number) until the exposure is correct.
If the image is JUST RIGHT: make note of the f-stop number
and flash power setting. These are now the settings that you
should always use for your B&A bleaching photos. Be sure to
always use the same lens magnification that you used during
this test. If you change the magnification, your distance to the
subject and your exposure will be different.
