Battery Devouring Digital Cameras and the People Who Love Them

Millions of people have fallen in love with their digital camera; and for good reason. They are compact making them easy to tote along anywhere a person may wander, they are capable of producing images of outstanding quality which can easily be shared online with others anywhere in the world, and with digital storage, they are a space saving wonder. In addition, digital cameras allow users to save the expense of film and developing. But perhaps the greatest attraction of these cameras is the control they provide over the images one creates during the editing process.

Unfortunately, most of those who love digital cameras have also come to know their dark side; their thirst for power. From the first touch of the button to power a digital camera on, setting the focus, shutter speed, zooming, and providing a flash for image capture, to reviewing images taken and editing, these cameras are energy junkies.

The good news is that there are things that can be done to help to make it easier to live with power craving cameras and to curb their appetite. Certainly, having a camera with rechargeable batteries is by far the best option and charging the battery per manufacturer's guidelines can help sustain optimal functioning. For the people who love their digital camera, there are also steps that can be taken in the way they use it to help reduce the rate of power consumption.

?When finished shooting, remove the batteries from the camera if it will not be used for another 2 or 3 weeks. This will prevent a trickling discharge that can occur when left in the camera.

?Use the on/off function appropriately. Certainly a digital camera should not be left on for any extended period of time as the energy is wasted. However, if another shot will be taken within a few minutes it is better to leave the camera on as it consumes a great deal of energy to power on/off. If the camera has a sleep mode, it is best to set the timer for that function to the shortest interval in case the user forgets to turn the camera off.

?Disable or don't use features that aren't needed. Zoom for instance uses a great deal of power. If the same result can easily be achieved by simply moving the subject or stepping closer, do that instead. Use of the flash function is also energy intensive. Flash should be used only when it will be effective. For instance, if lighting is already sufficient or the subject is out of flash range anyway, don't use the flash function.

?When possible use the viewfinder to set up a shot as the LCD screen consumes a great deal of battery power. Use of the LCD screen can improve some shots such as in the case of close-up/macro photography but in most instances use of the viewfinder is sufficient. (Remember, photographers operated without LCD screens for most of the history of photography!)

?Use other power sources when appropriate. For instance use an AC adapter when downloading images and use the computer for review and image deletion rather than performing such functions directly on the camera.

?Do things manually when feasible. From powering the camera off to focusing; auto anything takes more power.

?Some experts indicate that some types of media storage consume more energy as well. For instance, Compact Flash is said to be a more energy conscious form of storage than MicroDrive Media.

Certainly, the many features offered on a digital camera are convenient and desirable. Users merely need to be aware of the tremendous demands placed on the camera battery by these same features. Understanding this allows a digital camera owner to make a choice between ease of use and conservation of the battery.

Plasma TV and LCD TV: Televisions of the Future

Although both Plasma TV's and LCD TV's display a big picture in a thin case, there are many notable differences between the two devices.

The plasma television sets are larger than LCD's and measure about 42 inches. The size of the LCD is approximately 37 inches. But a 42-inch LCD TV would cost $1000 more than the plasma television set. The LCD TV?s weigh lesser than the plasma set. The plasma television sets are bulky and therefore they constantly require installation. They are well structured in order to prevent overheating due to constant usage by a means of proper ventilation.

The plasma televisions exhibit a contrast background and therefore are very appropriate for watching movies as you experience the enjoyment of a home theatre. LCD TV?s are mostly bright screened and appropriate if your room is brightly lit. The plasma TV?s do not appear lucid when the room is brightly lit. At the same time, the LCD TV's seem to emit strong rays when the room is darker.

You can watch your television from different angles when you are watching the plasma TV. The same convenience is not available in case of LCD as it bears a flat screen. As you move further we can feel the loss of brightness.

But there are a few disadvantages when you own a plasma television set. When it is linked to video, it often tends to leave an image for a long time. These images often get permanently etched on the screen. At the bottom of the screen, the text or the logos of the other networks are often seen and it causes a disturbance to the viewer. The estimated life of a plasma TV is around 25000 to 35000 hours.

According to Alfred Poor?s anticipations, the LCD television will continue to be an expensive set compared to the other televisions.

The Results Of Portable MP3 Player Reviews

A portable mp3 player makes it so easy to take your favorite songs with you almost anywhere that you want to go and under almost any conditions. Unlike CD players that have to read the digital music from a CD, mp3 players are much smaller and more compact. That's because the data storage devices used are much smaller than CDs, so the players can be tucked into a pocket of your shirt or pants and be almost invisible as you listen. But there are already many models to choose from, so here are some top picks from examining online portable mp3 player reviews and customer feedback:

1. In the flash memory category, which is the smallest and lightest of mp3 players, almost everyone still favors the Apple Ipod Nano even though some other great players are starting to provide more competition. But Apple dominates in the mp3 player area and the Nano shows why. It has an impressive 2GB of memory which can hold around 500 songs. and is compatible with both Windows and Mac computers. The firmware is upgradeable which is also a plus to keep you up to date with the latest changes in the mp3 field, and has equalizer presets to help you adjust the sound to your liking. The display is especially good even in low light situations, so this model gets a solid pick.

2. In the micro-drive player category the RCA Lyra is a fine choice with 5GB of file storage. It is also compatible with both Mac and Windows and has equalizer presets for customized sound. It's display is not quite up to the Apple standards, but otherwise, it's a solid, quality player.

3. As far as hard drive mp3 players are concerned the nod again has to go to Apple with the Apple Ipod. Apple totally dominates this category selling almost 90% of the high capacity hard drive mp3 players on the market. The Ipod has 30GB of storage space and that is enough to store the entire song collection of many people. It's display is again very good in all conditions, is compatible with both Windows and Mac, and comes with equalizer presets for custom sound. It also has the ability to play video files as well, with excellent picture and sound quality.

As you can see from the above list Apple is still producing the best portable mp3 players, and that is certainly reflected in the high number of units already sold to very satisfied customers. Expect that in the months and years ahead more challengers will emerge with better and better quality and features to give Apple a good run for the money, but at the time of this writing, Apple is still the best overall bet as voiced by many portable mp3 player reviews and consumer feedback as well.

Receiver And Subwoofer Crossover Setup

One of the I don't want to talk about it subject for owners of a home theater, is the receiver and subwoofer crossover setup.

One of the complicated things to do when you buy a home theater setting the speakers and crossover menu. Ok, first you must know that you just have to make one adjustment, you just need to make the adjustment in the receiver system and not in the subwoofer system like I was doing it the first time that I setup my first home theater; a waste of time.

Please don't forget to turn the subwoofer on before starting with the setup and putting it in 80 Hz crossover frequency.

When you are doing the setup in the receiver you'll see in the screen of your TV a question regarding wether you have a subwoofer running and what crossover frequency you want to use (many people just told that me the their receivers didn't give them a choice of frequency, that they only have the factory set at 80 Hz. that?s ok). like this the receiver will route all the deep bass frequencies below 80 Hz to the subwoofer via the subwoofer out jack from the receiver.

Note: Before you continue, remember if your receiver has 100 Hz and no other choice, you have to use that instead of the 80 Hz that I was explaining before, I only put 80 Hz because it?s the most common in most applications.

Ok, I was telling you, I recommend to experiment with all the settings, mix them all and see which settings is better for your room, depending of the size, you can select the large settings on your receiver for the front speakers ( the main ones) and small settings for the subwoofer and the surround sound speakers, like this the sounds with frequencies above 80 Hz will go to the front speakers and the sounds with frequencies below 80 Hz are going to the sub and the surround sound speakers. But remember, please, be a child!!! experiment with the frequencies and see which mix you like the most, because, it's your home theater, your room and of course your taste, everybody is different so, it's up to you.

Note: Please don't misunderstand what I am saying above, but remember when I am saying that if you put the subwoofer more than 80Hz, , that is its function and it could turn in to another speaker instead of the sub for your home theater.

Good Luck.

better things come from better people... be one of them. share what you know

LCD TVs

Liquid crystal display television or LCD TV uses LCD TFT technology, more often than not, for visual output as opposed to the conventional cathode ray (of the original TV) or plasma technology.

LCD television initially faced problems entering the market, particularly when it came to viewing fast paced action. Also, the viewing angle was rather limited. However, with the advancement in technology, these problems have more or less been wiped out. Today LCD television commands a burgeoning market, especially in the Asian region.

For quite a long time, the general consensus was that the technology used for LCD television was appropriate for small televisions only, and would invariably fall short of plasma technology when it came to bigger televisions. However giant corporations like Samsung, Sharp Corporation and LG Philips have challenged this notion by coming up with LCD televisions with distinctly large panels. 40 to 45 televisions were widely in the market a year ago. Sharp Corporation has successfully produced a 65 panel LCD television. In 2004, Samsung and Sony joined hands to build a factory, with the intention of manufacturing 60,000 panels every month. In 2005, Samsung proclaimed the successful completion of an 82 HDTV TFT panel. It is believed that the LCD market is potentially worth billions of dollars, and television is seen as the main market.

TVs based on S-PVA LCD panels produce good viewing angles. They also give sufficient contrast ratio for viewing scenes that are bright, as well as dark scenes in bright conditions. Also dynamic contrast technology improves contrast when one is viewing dark scenes in dark conditions. Also, there are LCD televisions that throw light on the background to help make dark scenes look darker.

Today, LCD televisions are offering greater viewing angles and better quality images. LCD televisions can also be deemed direct competition to the fashionable plasma televisions. However, LCDs are distinctly lighter and comparatively more durable.

LCD technology is non-emissive, in that it does not give off radiation like conventional televisions. Furthermore, their operation requires less power than plasma or CRT technology.

LCD TV Monitors

LCD monitors have an edge over other monitors as they have better resolution and sleek design. Due to the liquid crystal display technology, an LCD monitor can produce 16.7 million colors, which means, the tiniest of hues can be detected. LCD monitors are sleekly built, so they occupy less space on the table. They are also lightweight and very easy to transport.

LCD TV monitors are a combination of monitors used for computers and a normal television. They have a TV tuner built into them, which can allow them to function as both. They also have audio visual inputs, which can allow speakers and even woofers to be attached.

LCD TV monitors work on the principle of blocking unwanted colors from the white spectrum. Their screens have a large number of pixels, each of which twist and turn at appropriate angles to produce an image. The pixels are illuminated by a thin lamp or a projector LCD. Due to this, the LCD TV monitors can be designed very compactly. They also offer great viewing angles. Some LCD TV monitors can also produce good quality images when viewed at an angle as obtuse as 170 degrees.

LCD TV monitors also have non glare screens. This makes them easy on the eyes, even when viewed very closely. Also, they are not affected by light falling on them. Even in a bright room, the quality of image on an LCD monitor will be as crisp as in a dark room.

LCD TV monitors are available in general sizes of 19', 20', 21', and 23' and upward. Smaller LCD TV monitors are also available in sizes of 14' and 17'. LCD TV monitors provide good image qualities irrespective of their sizes. There are some complaints. LCD TVs suffer from high burn rates; which means the image persists on the pixels for longer times. Also some LCD monitors cannot run high density games, which require HD compatibility. Some LCD monitors also produce a ghosting effect. However constant improvements are being made in LCD TV monitors to make these anomalies redundant.

In order to make LCD TV monitors sleeker, companies make their buttons small. Sometimes this becomes an issue if the buttons are too small to be read.

A new type of LCD TV monitor is being designed, which will allow people to watch different programs on the same TV by just changing their angle of viewing.

Which Portable DVD Player is the Right Choice for You?

Of all the gadgets and technology we have available to us, portable DVD players are among the coolest. While our home AV systems have a standard DVD player, or even an HDTV & DVD player, while we're on the road we like to take our entertainment with us. Whether it's keeping the kids occupied in the back of the van, or amusing ourselves with the latest comedy, portable DVD players are the way to go.

But which is the best portable on the market? Which will give you the biggest bang for the buck? There are a number of differences you should be aware of before you make your selection. The first difference you'll notice is the price difference between a portable DVD and your home entertainment center version. Home versions - basic models, that is - start at under $100 on average, while a portable DVD player starts around $300-$400 for a good quality model.

The things you need to consider when choosing a portable DVD player are picture quality, sound quality, size of screen and battery life. If you choose one that has a great picture display but muddy sound quality, you'll likely be dissatisfied with your choice. By the same token, if your choice has excellent sound features but the picture bites - you'll need to reconsider which model you want. My advice is to see your choices in person - don't buy them over the Internet, unless you choose a vendor that has a great return policy with no re-stocking fees - just in case you don't like your choice when you see it in person.

If money's no object, you may want to start with the Panasonic DVD-LX9, which will set you back about $400. The advantage to this model is that it displays the best picture currently available on its 9-inch screen. A big downside for the Panasonic DVD-LX9 is the short battery life - look for about 90 minutes of playtime for your average movie. This is not for someone looking for hours and hours of movie watching enjoyment. For the price, it may be a better deal to buy a laptop with a 15-inch screen and a DVD drive - you'd have almost comparable picture quality and many more useable features with a laptop.

Panasonic does offer another model that you should take a look at - that's the DVD-LS50 - at about $350 it comes with sharp picture quality, excellent sound, easy-to-use features and about a 3 hour battery life. The screen is only a 7-inch, but that's pretty comparable to other models in this price range. It also has dual headphone jacks, so two people (i.e. kids in the back seat?) can listen at the same time without distracting the driver or others in the room.

If you're looking for longer playtimes - RCA offers a model (DRC618N) that starts at about $200 and registers a playtime of about 3 hours and 45 minutes. The 7-inch screen displays a good quality picture, but the sound quality leaves a bit to be desired. One advantage is the carry-case it comes with - which will strap onto the back of a car's headrest. This model has a single jack for headphones.

For those looking for the lower-priced models, GoVideo offers one (DP7240) at around $200 that has decent sound and picture quality - although not on par with the Panasonic and RCA models. Battery life on this one is only about 2 hours, but the package does include a battery charger, which will extend your playtimes as long as you're driving around. With only a 90-day warranty and a 7-inch screen, the GoVideo model may be a good cheaper addition to your viewing pleasure.
