If someone goes to an outlet to buy a
digital camera, it can be disorienting. There are hundreds of cameras available
and there are so many different types of camera
Digital cameras, both compact and DSLR, are
made in a wide range of sizes, prices and capabilities. Professional
photographers use larger, more expensive digital single-lens reflex cameras
(DSLR) for their greater versatility and many amateurs use compact cameras for
the simplicity.
Compact cameras are designed to be taking
causal and simple snapshots. They are really tiny and portable. They are easy
to be used and the quality of the picture is more compact and simple because
the compression of the picture can be only stored by JPEG. Most compact cameras have a built-in
flash. And because of that, it limits
the motion picture capability. This camera has zoom lenses but the range is
less than DSLR cameras.
Generally, a contrast-detect autofocus
system, using the image data from the live preview feed of the main imager,
focuses the lens.Typically, these cameras incorporate a
nearly silent leaf shutter into their lenses.
Digital single-lens reflex cameras (DSLRs)
are digital cameras based on film single-lens reflex cameras (SLRs). With an DSLR camera, you see what the lens
sees, which means the
"Light
passing through the lens is reflected by a mirror and brought to focus on a
ground glass. The mirror causes a reversal of the image seen on the ground
glass, but the addition of a pentaprism mounted over the ground glass allows
the camera to be used at eye level, with the image seen upright and in proper
left/right orientation. An instant before the exposure is made, the mirror
swings upward, and the shutter is activated. A single control cocks the shutter
for the next exposure, advances the film, and returns the mirror to focusing
position."(from The Digital SLR guide)
You
can change the lens for different occasions. There is a variety of the lens and
this makes it produce high quality photos with large image sensors and there
are no limitations for action photography.
Knowing your camera is the first step to take pictures but do you remember what I
said at the end of my post last time? I met
Dave Labelle and asked him about what kind of camera is good?
And
here is what he said. “People look at my camera and say, ‘ah, that’s a great
camera, I bet it take good pictures.’ And I say, ‘No it does not. I take good
picture.’ The kind of camera that you use is not nearly important as the
subject matter that you choose take and your motivation.”
Like he said, you are the one who is taking
pictures. If you are a good photographer and nevertheless follow your heart and
not your lens, you do not have to worry about what camera you are using. Know
your camera, but know your purpose and reason to take pictures too.

This was encouraging for me to read, because I have always been interested in photography but have never had the means to buy a really nice camera. However, it was great learning about the different times of cameras, and what a digital camera is composed of.
