e suggest using either a wall mounted lightbox with a built-in slave flash or a bare slave flash
to eliminate shadows on the facial photos. If you are using a bare slave flash, we have found that
it works best when placed precisely behind the patient’s head, facing toward a white background.
You may need to adjust the brightness on the background lighting that you use in order to generate
accurate soft tissue hues. Overhead fluorescent lighting may also affect the color of the images.
You can replace the fluorescent bulbs with halogen lighting to produce better color images.
Professional photographers spend time setting up their studios for just the right picture. e also
have to invest time in setting up our offices for the right lighting for digital images.

Tips for Taking Extraoral Images
hen you are taking the lateral head image, make sure the patient’s head is level, with no tilting or
canting. e suggest that you place a mirror in front of the patient with a vertical line and have them
align themselves to it. This will make it easier to align the photos to the x-ray tracings. You should
capture the photo with the camera lens aligned with the patient’s Frankfurt Horizontal plane to
ensure the most accuracy.
For intraoral photographs, we recommend switching to the Manual mode on the camera. This allows you to take higher
quality pictures than in the auto mode, and allows for greater control over the exposure and depth of field of the images. The
manual settings only need to be set once, as the camera “memorizes” these settings.
To access the manual set-
tings, turn the camera on by
setting it to the setting
located on top of the camera.

Adjusting ISO film speed:
The ISO settings define how quickly the camera
takes the picture. A higher ISO number means the
camera will take the picture quickly, so there’s less
chance of blurry pictures. This is especially useful
for intraoral pictures.
To set the ISO settings, hold down the flash button
on the back of the camera and rotate the “Command
Dial” located at the top of the camera as shown:
The letters ISO should appear in the Control Panel.
You should stop rotating the dial when ISO 400
appears.
3Adjusting Aperture Priority:
For a better depth of field, you should adjust the Aperture settings. Setting the cam-
era on “Aperture Priority” allows you to adjust the camera so you can take pictures
where the foreground and the background are both sharp. This is crucial for intra-
oral photographs.
To enable “Aperture Priority”, hold down the “Mode” button and rotate the
“Command Dial” located on the top of the camera until the icon appears:
Next, rotate the “Command Dial” all the way to the right until the you reach an F-
Stop of about 9.0, which appears in the control panel screen at the top of the cam-
era. You will need to use the Zoom buttons to fine tune the value. The
macro icon will then appear yellow on the LCD monitor.

Adjusting the Metering:
Metering allows the camera to determine how much light is necessary for illuminating a certain pic-
ture. You should use Center-Weighted Metering for intraoral pictures, as it allows you to preserve
background detail while providing the right amount of light output for the teeth. To select this, click
on the Menu button on the back of the camera and use the Selector button to navigate to the Metering
option, as shown below. hen Center- eighted is highlighted, push on the right arrow of the
Selector button to select.
Adjust the Speedlight settings:
To eliminate overexposure for intraoral pictures, you can adjust the flash output of Nikon’s
Speedlight. To do this, click on the Menu button on the back of the camera. Then, click on the left
arrow of the Selector Button. Scroll down to the “S” option and click to the right. The screen will
show “Setup 1” at the top. Scroll down past the last option on this page to get to “Speedlight Opt.”
Click to the right and select “Variable Power”.
e recommend using a setting of -0.7 for frontal and buccal intraorals. However, you may need to
adjust this value to fit the lighting in your office.

Tips for Taking Intraoral Images
e recommend taking the frontal and buccal intraoral pictures about 6 inches from the patient’s
mouth. This allows the flash to meter correctly without overexposing the picture. ith the camera’s
high resolution, you will not lose clarity when cropping the images. hen you are taking the frontal
and buccal intraoral pictures, make sure to take the picture at a 90º angle to the teeth. Also, try to align
the horizontal plane of the camera with the patient’s occlusal plane. This will save time, as you will
not have to rotate the image inside Quick Ceph later.
For the occlusal pictures, we recommend taking the images approximately 10 inches away from the
patient’s mouth. Due to the height of the flash, taking the image closer would result in the patient’s
lips obscuring the flash. Also, pictures taken too closely may not fit within the cropping windows.
Occlusal pictures tend to be dark compared to the frontal and buccal pictures. e rec-
ommend increasing the aperture of these pictures by one or two F-stops by rotating the
Command Dial slightly to the left. You can also set the camera to the A-mode and turn
on the Macro feature. For upper occlusal images taken with a mirror, we recommend
flipping the camera upside down to eliminate shadowing.

tures appear too
