Back
to Basics: which is the best camera for dental photography?
Which
is the best camera for dental photography is a question that still remains
unanswered for millions of dentists world-wide. This particular blog aims to
reduce the confusion amongst the minds of the dentists and help them choose a
camera for dental photography.
Let’s
begin with what we should expect from an Ideal camera for dental photography…
Listed
below are the expectations from an ideal camera for dental photography and on
the right hand side a few popular camera types. For every point on the left
marks have been given under each camera type on a scale of 1 to 5 depending
upon how much they hold true to that particular point.

It is extremely clear from the figures above that a DSLR
camera has no real competition when it comes to serious dental photography.
A bridge camera is not for serious photographers while
sub-compact (point and shoot) and mobile phone camera come under least
preferred category of usage.
Let me share a note from Wikipedia over here…
“A point-and-shoot
camera is a still camera designed primarily for simple operation.
They are popular with people who do not consider themselves photographers but
want an easy to use camera for snapshots of vacations, parties,
reunions and other events. Point-and-shoot camera sales declined after about
2010 as smartphones overtook them in such uses.”
About DSLR (Digital Single lens reflex) Camera:
DSLR Cameras are increasingly becoming a type of camera that
is in the reach of the average photographer as prices fall and as manufacturers
develop more user friendly models.
DSLR stands for “Digital Single Lens Reflex”. In simple
language, DSLR is a digital camera that uses mirrors to direct light from the
lens to the viewfinder, which is a hole on the back of the camera that you look
through to see what you are taking a picture of.
When you look through the viewfinder on the back of the
camera, whatever you see is exactly what you are going to get in the
photograph.
The scene that you are taking a picture of passes through the lens
in a form of light into a reflex mirror (#2) that sits at a 45 degree angle
inside the camera chamber, which then forwards the light vertically to an
optical element called a “pentaprism” (#7). The pentaprism then converts the vertical
light to horizontal by redirecting the light through two separate mirrors,
right into the viewfinder (#8).
When you take a picture, the reflex mirror (#2) swings
upwards, blocking the vertical pathway and letting the light directly through.
Then, the shutter (#3) opens up and the light reaches the image sensor (#4).
The shutter (#3) remains open for as long as needed for the image sensor (#4)
to record the image, then the shutter (#3) closes and the reflex mirror (#2)
drops back to the 45 degree angle to continue redirecting the light into the
viewfinder.
Conclusion: If you
require a true distortion free image for your dental practise with wide variety
of settings and good flash and lens attachment options always insist on a DSLR.
