Nikon Coolpix 995 Help

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. When Center-Weighted 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".

We 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

We 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. With the camera's

high resolution, you will not lose clarity when cropping the images. When 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. We 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.

Adjusting Images While in QCIPro and QC2000

Images taken while the camera is flipped upside down can be rotated easily in QC2000 and QCIPro.

For information on image editing, please see Chapter 2 in the Quick Ceph Manual (downloadable

Please Note: We only recommend this camera. We do not manufacture it. If you have technical difficulties,

Systems

After all of the settings

have been selected, the

Control Panel at the top of

the camera should resem-

ble the image shown

below.

Manual Mode with:

Macro setting

Anytime Flash

ISO 400 setting

Aperture Priority

Center Weighted Metering

Reduced Flash output

We recommend pur-

chasing an additional

Nikon EN-EL1

rechargeable Li-ion

battery. The pro-

grammed settings

will be lost if the bat-

teries are taken out

of the camera for

more than 2 hours.

If the occlusal pic-

tures appear too

dark, you should set

the camera to the A-

mode and turn on

the Macro. This

adds more light to

the occlusal pictures.
