How Digital Camcorders Work
by: Richard Gazzo
The first camcorder was invented by Jerome Lemelson in 1980. And since that time the first bulky analog video camcorders have evolved into the modern digital camcorder, so small they can fit in the palm of your hand, and so clear they rival even professional broadcast video cameras.
Consumers have been using camcorders since early 1980s. Since then they have gotten better and cheaper, with prices starting at only a few hundred dollars, making DV camcorders affordable for anyone. Shooting home videos is fun, everyone loves filming their families during special events. From your kids birthday, your son's soccer game, to the family trip to Mexico, but how exactly do video cameras work?
Digital video cameras convert analog video into a digital format. Digital video camcorders take the analog information in the video camera and then translate it into bytes of data. Digital video is converted from moving images to a stream of zeroes and ones. The digital video camcorder records the bytes of digital information onto one of three items, a hard disk, a dv tape, or a DVD. From there you have the ability to transfer the video to your computer. You can then edit the video, email it to friends and family or even add the video to a website.
The digital video process begins at the lens in the camcorder. The lens stores and then focuses light from the video that you are capturing onto the image sensor located behind it. Because the Charge- Coupled Devices (CCDs) used by camcorders are capable only of measuring the amplitude of the light hitting the photodiodes on their surfaces, a system of filters is required to establish just what color that light is.
Another part of the camcorder, that plays an important role is the viewfinder. Originally view finders where black and white, as time progressed viewfinders have evolved into color LCD screens. This is a necessary part of the camcorder, it lets you see what you are filming. Newer models of viewfinders even let you add effects to your video via an LCD touch screen while you are filming.
Newer DV camcorders can not only shoot high definition video (up to 720 lines) but models such as the Sony hdr-fx1 hdv camcorder, Canon xl2 and the Canon zr200 mini dv camcorder even offer digital still image capabilities. You can snap crystal clear images with resolutions up to 1024 x 768, perfect for family photos. Need to email your videos to friends and family across the globe, no problem. With the MPEG feature you can even email short video clips to any one with an email address! Grandparents in Europe can see your daughters birthday 4 minutes after you have filmed it in the U.S.A!
Even though current digital video camcorders come in a range of sizes and shapes, the techniques used to convert moving pictures hasn't evolved much. But the styles of digital camcorders have evolved. You can find digital video camcorders come in all types, from dvd camcorders to mini dv camcorders. As technology changes video is not restrained to digital video cameras. cell phones now have the capability to shoot video and email the clips instantly anywhere in the world. It's hard to predict how far video technology can go, the sky seems to be the limit.

Easy Guide to Buy Digital Camcorders and DVD Camcorders

A camcorder is a portmanteau word made by combining 'Camera' and 'recorder'. A camcorder is a portable television camera and videocassette recorder. It is an electronic device for recording video images and audio onto a storage device. It contains both camera and recorder in one unit. The camcorders generally contain digital cameras. A camcorder having digital camera or digital technology is known as digital camcorder. A camcorder having dvd facility is dvd camcorder. A camcorder is powered with a camcorder battery.
Sony introduced the first camcorder in 1983, followed by Kodak in 1984. The first camcorders combined the video-camera with an existing full-size VHS/Betamax recorder. These camcorders were large devices that required a sturdy tripod or strong shoulders to stably support the camera's bulk. The majority of these were designed for right-handed...

Don't Use Markers to Label CDs and DVDs
Don't Use Markers to Label CDs and DVDs
by: Adam Platzer
Many people use markers to write on the surface of their CDs and DVDs when labeling their media.
What most people do not know is that using markers, such as Sharpies, ballpoint pens, or any other sharp object can be very damaging to the media.
Most markers contain chemicals that create oxidation, which can deteriorate the CD or DVD.
The oxidation can ruin the aluminum, which covers the surface of the media and ultimately can destroy the data on the disc.
Additionally, these types of markers can damage the physical structure of the disc.
There are a couple of ways to avoid these problems.
Special pens are now sold which are made specifically for writing on media.
One brand is called Staedtler Lumocolor CD/DVD Markers (pictured to the right).
Another tip to keep in mind is that off the shelf markers can be used on media that has...

Defensive Driving - What Are The Choices?
Defensive Driving - What Are The Choices?
by: Mark Stone
At some point in our driving years I suspect most all of us have to take defensive driving, whether to get rid of a ticket or maybe to just lower our insurance. For many years you only had one option, traffic school. But times and the options have changed.
Traffic school used to consist of getting up early on a Saturday morning or spending two nights during the week sitting in a classroom, listening to a instructor speak in a monotone voice and watching old 16mm films with 1950?s cars and actors explaining the right and wrong way to drive a car. Although that option is probably available if you look for it, these days defensive driving class has gone high tech.
So what are the choices?
* - Traffic school with a twist: Some of the options you can choose from if you?re looking for an in-class experience is humorous traffic school, traffic school with a meal, juggling and magic...
