Major Components
All video cameras contain 3 major components - the
lens, imager, and recorder. The lens gathers and
focuses the light on the imager, which is normally
a charge coupled device (CCD) or CMOS sensor IC.
Finally, the recorder will encode the video signal
into a form that can be stored. Commonly, the optics
and imager are known as the camera section.
The optic lens is the first component in the camera
section's light path. The optics normally have one
or more the following adjustments:
1. aperture - controls the amount of light
2. zoom - controls the field of view
3. shutter speed - captures continuous motion
In most consumer units, these adjustments are
automatically controlled by the video camera's
electronics, normally to maintain constant exposure
onto the imager.
The imager is the eye of the camera, housing a
photo sensitive device or devices. The imager works
to convert light into an electronic video signal
through an elaborate electronic process. The
camera lens projects an image to the imager surface,
exposing the photo sensitive array to the light.
The light exposure is then converted into an electrical
charge. Towards the end of the timed exposure, the
imager will convert the accumulated charge into a
continuous analog voltage at the imager's output
terminals.
The third piece, the recorder, is responsible for
writing the video signal to a recording medium,
such as magnetic videotape. The recording function
involves many steps of signal processing, and
historically, the recording process introduced
some distortion and noise to the stored video,
such that the playback of stored signal may not
retain the same detail as the original live feed.
All but the most primitive of video cameras will
also need to have a recorder controlling section
which will allow you to control the camera. You
can also swich the recorder into playback mode
for reviewing your recorded footage.
The image you recorded doesn't need to be limited
to what appeared in the view finder. For a
documentation of events such as those used by the
police, the fields of view will overlay such
things as the time and date of the recording along
the top and bottom of the image.
As you can probably tell now, a high definition
video camera is very complex indeed. There are
several other parts involved as well, although the
above are the most important. A HD video camera
is very complex in build, making it something
that is more than worth the time it takes to create.

Art or Science: the True Nature of Digital Photography
What is the true nature of digital photography? Many people have been asking this question for a long time. In fact, when people ask the question about the true nature of digital photography, they often mean to ask whether it is art or it is science.
Here are some arguments for both sides:
A) Art many people consider digital photography as an art because it allows for an expression of emotion. They believe that digital photography is a continuation of the art of drawing or painting. You see, digital photography is just like painting in the sense that although it does take accurate pictures of reality, it also allows for some modification through the various digital tools available today.
Even without the editing many people still believe that digital photography is art because of the fact that it does take an artist's eye to find a great subject of digital photography. The nature of digital photography as an art has something to do with the fact that an artist is able to express emotions and statements through visual subjects.
The supporters of the artistic nature of digital photography also argue their case by stating its ability to convey emotional messages through aesthetics. The beauty of each photograph, of course, needs also to be credited to the person taking the pictures. One of the strongest arguments for the artistic nature of digital photography is the fact that the picture is rarely really what is seen with the naked eye. Through the camera and computer, a person can alter the image in order to present what he or she wants to show.
B) Science some people argue that science is the true nature of digital photography. One argument is that photography, unlike painting, actually comes from something existing and not from a painters mind or emotion. This can be very persuasive since, indeed, a photographer does not actually make photographs. He or she merely takes them.
Another argument regarding the scientific nature of digital photography is the fact that the editing that people do and adjustments that photographers make are based on a series of steps that can be narrowed down scientifically. People who argue for the scientific nature of digital photography may reason that the same series of steps can be taken in order to achieve the same results. There is a certain quality of constancy about digital photography that renders it a science.
But what is the true nature of digital photography? We have read the various arguments supporting science and art. There appears to be no solution to this question, right?
The true nature of digital photography will always remain to be a paradox. This means that though it can be considered as an art, it can also be considered as a science. When is the paradox of the nature of digital photography solved? Well, it is solved when a person takes a digital photograph.
The true nature of digital photography lies in the hands of the person who takes the pictures. The way a person treats the process defines the nature of digital photography for him or her. It is not absolutely art nor is it absolutely science. The true nature of digital photography is a paradox. It might seem to be contradictory, but it is somehow true.

HOW TO FIND THE BEST DIGITAL CAMERA
It seems that every month, if not every week, different manufacturers are coming up with the latest digital cameras to entice potential clients. And it's just not working for us!
After spending sizeable amount of time at the mall figuring out which is the best digital camera for us, we finally have enough money to buy for that eye-popping, 7 mega pixel, 10x digital zoom, potable, candy colored, up to 512MB expandable memory of super hi-speed SD memory card and not to mention very portable, (that will be the envy of almost everyone we know). We march to the mall armed with our life savings and lotsa pride in ourselves, when we pass by a new display - an eight mega pixel, up to 1G expandable memory, with built it mic and stereo surround, video playback capable, with 22 scenic modes kind-of-camera. And we sigh because the producer of this amazing gadget claims that this is the best digital camera yet out in the market. And so as we always want to have the best, armed with our life savings and a few credit cards, we buy the est digital camera. But then again, that doesn't last too long, after two months or so, there's another est digital camera.
And so it confuses us. What makes a digital camera, the best digital camera?
Well, there are certain factors to consider when looking for the est digital camera for us.
MEGAPIXELS. One of the most important features of digital camera to make it into the best digital camera category is its mega pixel property. The higher the mega pixels the better the actual photograph will come out. A mega pixel is equivalent to one million pixels. The resolution of your image is based upon the mega pixel property of your camera. This means that as you enlarge the picture, you would get more detail and less blurry colors.
LCD SIZE. The best digital camera will always have a large LCD to help you frame your subject without having to squint to the viewfinder. This is also helpful when reviewing your images, some cameras enable touch up and editing features with its LCD. A 1.5-inch display is average, a 2-inch LCD display is good, but the best LCD size would be 2.5 inches or higher.
ZOOM. Most digital cameras have both digital and optical zoom. A higher optical zoom is always better than a higher digital zoom. Digital cameras are usually furnished with optical of between 3x to 10x. The better the optical zoom, the higher it climbs up to the best digital camera category.
MEMORY CARD. Always make sure that your memory card is the right one for your digital camera. There are different types of memory card like the xD, SD, Flash card and the likes. And these types of memory cards go with certain types of digital cameras. of course memory storage is also up there in choosing the best digital cameras. Choose the size of memory that you need, if you're a photo junkie, you might need more than 32MB. Memory cards can go up to 1G.
The key point to find the best digital camera is to find one that will best fit you and your lifestyle. Don't just buy the latest or the one that claims they are the best digital cameras out in the market. You wouldn't want to buy a DSLR and use it with your home activities or family outing and have to lug it around?! Or you don't want to buy the latest point and shoot camera when you're serious about being a professional photographer. (Of course, you can use this for starters, but if you're not a novice photographer anymore, you wouldn't want to get this kind of camera.)
Actually, the best digital camera is the one that you will enjoy and use. Not the type that you'll just leave rotting in its box or after a few weeks of usage or so, up there in the attic.
