Trouble Shooting Most Frequent Problems
1. OUT-OF-FOCUS CLOSE-UP PICTURES:
a. Usually too close to the subject, working distance is 4 to 7 ½ inches.
b. For most close-up pictures, when you put the camera on "C" it
zooms in a predetermined amount. DO NOT ZOOM IN MORE
EXCEPT FOR BUCCAL AND QUADRANT PICTURES. The "C"
setting zooms in the perfect magnification level for a natural smile,
retracted anterior, and occlusal views. For buccal corridor and
quadrants, zoom in all the way.
c. Maxillary full arch out-of-focus. Try this technique.
i. Get the full arch in the view finder,
ii. Pivot and focus on a pre-molar, push the shutter button until you
feel the first "stop," do not lift your finger off of the shutter button,
then pivot back to the full arch and take the picture.
d. Setting focus then changing distance. Once you set the focus keep
the distance.
e. Focusing is a two step process; push the shutter button until you feel
the first pressure point this lets the camera focus; then push down all
the way and the picture will be taken.
f. Anterior picture blurry. If teeth are parted, focus on a tooth, not
between the teeth.
g. Low light conditions. The camera needs sufficient light.
h. The extension and or close- up lens are not on.
2. OUT OF FOCUS PORTRAIT PICTURES:
a. Extension adapter is left on.
b. Low light conditions.
c. Setting focus then changing distance. Once you set the focus, keep
the distance.
3. SHADOWS IN LOWER RIGHT CORNER OF THE PICTURE:
a. Finger is covering flash.
b. You have zoomed out toward wide angle. Put Mode Dial on "C"
and don't tinker.
