High Definition Video Cameras, Batteries and Capturing Still Images

2009-04-26T20:46:00.000-07:00

The vast majority of cameras these days have a tilting feature that will provide a tilting feature inside the camera, although this feature is one that you should not touch unless you are going to be editing the video on the computer. The title effects on a lot of them are very limited and cannot be removed after they are implemented. The vast majority of of high definition video cameras have a rechargeable Li-ion battery but it is also useful to have spare batteries in case the battery that you are using gets drained of it charge while you are on the road recording. Remember that each battery is unique to each model or brand and be careful not to buy the wrong battery. Most of the new batteries allow you to capture digital still images on to a memory stick or some sort of storage device. The most popular type of memory stick is SD or MMC these cards or not really memory sticks but serve the same purpose. If your cameras does not offer features that let you take still images you can use an editing program to capture still images.

The Digital Transition - My Experience With DTV Converters

2009-04-15T17:55:00.000-07:00

To my wonder there is some confusion to what the different television standards mean. ATSC standards are currently what is known DTV but some of them like 720 and 1080 are what are known as high definition television or HD television or whatever term you want to call it.There are different standars for eache resolution. These standards are much higher that those that will be decoded by DTV boxes. Those that will be decoded by those boxes are the that are mostly similar in resolution to old analog NTSC standards that are known as SDTV. Do not be confused by these terms they are different in everything from the screen's aspect ratio to the amount of pixels and depending on the particular case even the way that images are parsed on the screen. Now if you have an old analog television set and want it to be useful after the summer tv transition you have to buy a converter box not anything related to HDTV. Just remember that these boxes are useful to watch broadcasts that you would commonly receive through your normal antenna. Not satellite or DirecTV stuff. If you get a coupon, the DTV box will cost you around $40 dollars but if not, you will have to pay $80 or probably even a little more.

From my personal testing, I can say that DTV does look better than analog and there is quite a noticeable drop in the amount of interference that used to be introduced into my television set through the antenna. In the worst cases the image gets a little blocky but it is an improvement over the color distortion and the prominent ghosting that used to affect the image I received. I am also able to watch channels that I could not previously which is strange if you consider that the transition was delayed for the sole reason that people were receiving less channels than they used to. If this happens to you I suggest that you get an antenna with a higher gain. Just do your own testing first.

Some Words about HD Video Cameras and HDTV

2009-03-26T19:19:00.000-07:00

High definition has been creating quite a lot of consumer interest due to all the marketing and campaigns that are circling around especially with all the promotion that cable television providers are doing hoping that you buy an HD cable box to watch television in HD. Perhaps you may not be aware of that HD is delivered in a different aspect ration that regular television. HDTV uses an aspect ratio of 16:9 format while regular formats are usually 4:3. The average consumer is confused about what is high definition and what does it truly means since most companies that are involved with it just can't agree on using a single standard. The standard that is currently getting the most support is 1080i also known as 1080 interlaced. This means that there are 1080 interlaced lines. Regular tv gives you 525 lines so the difference in quality is quite dramatic if you have the necessary components to watch video the way it was supposed to.

Cameras that offer HD are simply the best cameras that money can buy. They are obviously more expensive than normal digital cameras, with some models reaching upwards towards 90,000$ and above! These types of cameras are normally for professionals, people that their job depends on a video camera, as the average person would never be able to afford such an expensive type of HD video camera or even think of paying such an amount of money for it anyway. The average high definition video cameras will run 800$ and up, a rather affordable price for any enthusiast. High definition cameras offer you the chance to shoot high definition pictures and videos, and send them to friends or family. You can also save your shoots to disk or memory card, then take them with you everywhere you go. If you've yet to see a HD video camera, you'll probably find yourself amazed at the quality of the video. The zoom offered with these cameras are amazing, as many can get above 100X! Shooting up close and personal is never a problem with HD cameras.

Digital Photography - How to Take Advantage of White Balance

2009-03-17T15:22:00.000-07:00

If you have taken a photo of a predominately white area only to discover that what was supposed to be white looks kind of blue instead then you have experienced what a digital camera's white balance is supposed to prevent. White balance is a sensor that handles the job of analyzing the conditions of a scene and makes the necessary adjustments so what is white about a picture looks like it is supposed to and not show a shade or should I say an aura of blue.

The main idea behind white balance is to help make pictures look as natural as possible and is one of the main advantages that digital photography had over traditional film. In the case of film, you buy with a certain light condition in mind and if there is any change you have to change the film that you are using of perhaps hope to be able to fix any errors in post production.

The vast majority of all digital cameras have an automatic white balance and/or some presets that you can use to correct any errors. Sometimes you may want to enhance colors on a picture. The best way to do this is using some set ups such as a "cloudy" setting to give a warm tonality to the picture. This helps give the picture a more warm feel. To really know how to take advantage of white balance as a way to make changes to the feel of the pictures you have to experiment. Over time the best setting for a situation will come to mind spontaneously .

Should you Buy an HDTV Tuner for PC?

2009-03-09T01:28:00.000-07:00

First of all computer monitors are digital by nature and use progressive scanning methods. This makes computers very good at displaying HDTV images. Also, it is important to note that newer computer monitors are able to display resolutions that can match and even beat those that are offered by even the newest High Definition Television sets. These facts together makes a PC HDTV tuner the only missing component to be able to watch on air High Definition broadcasts and QAM unencrypted cable. However older HDTV computer tuners suffered from poor signal reception, today it is a whole different ball game as newer model are able to display good results on low signal circumstances making them excellent products for people on the go in the case of USB sticks or home theater alternatives for those who prefer to have their trusty desktop take the role of a big home theater.

Tuners that are designed for computers come in different varieties. We can classify these tuners according to how they are connected to the computer itself. For example, some receivers are designed to be connected by a computers PCI slots. These devices are more suitable for desktop PCs considering the fact that these types of slots are only available in desktop computers. PCI connected tuners commonly come from the factory with some accessories such as cable for connecting, remote controls, and a small box to receive signals from the remote control itself and perhaps some knobs for manual handling.

USB tuners usually require less work and have less equipment to connect that their PCI counterparts it is quite common that these gadgets are shipped with a software disc and even a small portable remote control. Still, it is worth keeping in mind that some tuners are dependent on computer resources while others are not. It is recommended that the consumer reads the specifications for the model before deciding which model to buy especially if its to be used on an older computer. Some computer HDTV tuners including USB sticks have connections for cable which helps add some more usability to these contraptions adding to the overall usefulness of the product itself. Still it is always a good a idea to have a little knowledge before choosing an HDTV tuner for your PC.

About Portable Usb HDTV Tuners

2009-03-08T16:46:00.000-07:00

A laptop usb HDTV tuner is relatively small device that takes the functionality of tuners designed to provide high definition television signal decoding functions to a PC using USB technology. This gadgets are built with the traveling student or business man in mind making then perfect to carry in a Laptop bag. The main idea behind the concept of the usb tuner is to help people on the go receive On Air broadcasts transmitted in HD with the convenience of not having to deal with a big add on device. Instead these tuners are light weight and small, looking somehow similar to a pen drive.

What are the downsides of portable Usb tuners?

While the concept looks great at first there are somethings to consider. Reviews vary greatly between each usb tuner model. Some users experience exceptional quality sound and picture with some while other models have a tendency to de-synchronize audio from video. This creates a lag where video appears to be moving before sound or vice versa ruining the experience, this complaint has been apparent with older models and usb tuners that are often made by unrecognized brands. Usually the gain of an Esb tuner is lower than that of set top boxes and PCI tuners due to the fact that space limitations restrict the use of external antennas. This makes these tuners rely on internal antennas that resembling more like antenna-less cell phones. This fact is important to be aware off since overall performance will be greatly affected if signals received are not strong enough for the HDTV tuner.

What is an HDTV Tuner?

2009-03-08T16:42:00.000-07:00

An HDTV tuner is a receiver that decodes signal transited in one of the ATSC formats that are designed to be used to define the standards for High Definition Television. These devices decode signals and convert them so they can be displayed in a monitor either a computer or a High Definition Television set. IT can receive on air broadcasts that are transmitted by local TV stations or cable sources that are in fact transmitted using unencrypted QAM formats.

Tuners that are built with that computer mind are very different from those that are built for television sets. The ones that are built for television sets are commonly referred to as set top boxes or just receivers and may be even be built in the television set itself depending in that model in question. And like the name implies are boxes similar to what a cable receiver would look like in appearance while those designed with a computer in mind can vary from PCI cards which are used for desktop computers and are connected in PCI slots in the PC's motherboard or USB sticks that are preferred for laptop users and are relatively small making them travel friendly.

It is important to know that tuners are not necessary to watch High Definition television if you are subscribed to Dish Network, Direct TV or mostly any digital paid service. In fact they are really useful when it comes to receiving free broadcasts or recording them if the function is built as with some HDTV television sets. In summary the use of these devices is somewhat limited when we compare the circumstances when you may need one and when you may not.

If in fact you buy a High Definition television set that has one built in you just saved yourself some trouble and perhaps some money. It is still worth keeping in mind that for on air local channels transmitted in High Def a tuner is a must, and if it has recording features it can really save you from missing your favorite shows so never underestimate the importance of an HDTV tuner in your home theater or as part of your computer's accessories. They can be real life savers for any television enthusiast.
