LCD TV's (liquid crystal display) are on of the most popular types of HDTV's on the market today. LCD technology has been in use for several years. Many of us remember the days of CRT computer monitors but most people have moved on to LCD computer monitors. The technology used for computer monitors has evolved to high definition televisions and they are growing fast.
LCD HDTV's main competition is plasma television. Up until recently, plasma was shockingly more expensive tha LCD but with advances in technology, their prices are becoming more similar. So if pricing is pretty similar, then which TV is the better option? Each has its advantages and disadvantages. For now, we will be focusing on the advantages of LCD televisions.
Advantage 1: Screen Glare. Plasma TV's have a reflective, glass looking screen. LCD screens have more of a matte finish. Because of this, you don't have to worry as much about having too much light in your room. LCD TV's are a great option for theater rooms, kitchens, living rooms and just about anywhere else. You don't have to be stuffed in a cave to see the picture.
Advantage 2: Energy Use. LCD TV's use much less energy than plasma TV's. Running a plasma TV could cost you several hundred dollars more per year just to own. With the recent "green" movement, you will be helping the environment by avoiding plasma.
Advantage 3: Size. LCD is available in a very wide size range. You can get LCD screens anywhere from 5 inches to 65 inches or higher. Plasma screens are usually only available in the 40 inch or greater range.
Advantage 4: Price. Even though plasma's are getting cheaper, you will still save a few bucks by going with a LCD. Most people can't even tell the difference between LCD and plasma so save a few bucks and go LCD. With our current economy, who doesn't want to save money?
Advantage 5: Wall Mounting. You can wall mount most LCD or plasma HDTV's. Wall mounting is a great option for several reasons. First, it looks very styling and modern. Second, it frees up space in small or cluttered living rooms. Lastly, you can mount them with a swing arm so you can position the TV in any direction that you want.
These are some of the most common advantages listed for LCD TV's over other types of high definition TV's. Each has its pro's and con's but these advantages may persuade you to buy LCD.
Perhaps nothing else has taken the technology world by storm with as much vehemence as has Apple's iPhone. These days, everyone and their mother has a smartphone, a major portion of which have a little apple residing on the back. The iPhone has revolutionized the way that people play, do business, and communicate in one fell swoop. With Angry Birds as its unofficial mascot, the popularity of the iPhone app store has transfigured the software industry, making mobile apps the hottest thing since Steve Jobs put pretty type on the screen.
So what is it about Apple's iPhone and their other array of 'i' products - iTouch, iPad, iWhatevercomesnext - that has us all wanting to slide our fingers across a glassy surface? One thing that is seemingly inherent to Apple's products is a level of (how shall I put it?) wowness. I know that is not a real word so I am going to use the word iSnazzy instead. Apple things look cool. They exhibit a sort of sophisticated "I come from the future" look that immediately grabs the attention and gets the fingers itching. Surely there must be a teleportation button on something that looks so cool, you think, and are only mildly disappointed at the lack thereof because you are so busy killing zombies with plants.
And if the look of the phone itself was not enough, the ability to customize it to your personality fills in the remaining gaps. Out there in accessory land, smart people are selling clothing for smart phones. The line of apparel includes such things as the iPhone two-piece case, the iPhone mesh case, and even the iPhone kickstand. And what cool new gadget doesn't need a kick stand? Go on, name one. Knew you couldn't. The cases and accessories come in more colors and patterns that French wallpaper. Enough said.
But is this all that makes iPhone such a ubiquitous tool? Certainly not. The real power of the rectangular object, small enough to slip into a pocket or a purse, is in its ever expanding variety of functions. It's a phone, it's a game system, it's a camera, it's a book, it's a mobile office, it's a room full of CDs, it's a GPS, and it's a flashlight for heaven's sake. The fact is it's anything the programmers can make it. What is your iPhone? You'll find out tomorrow, because tomorrow you will change it. It changes as you do. You start exercising and it becomes your coach. You start dieting and it becomes your calorie counter. I think I've made my point.
Now, iPhones are not the only option out there in the world of smartphone technologies, and the future may see them relegated into the realm of Betamax and the Sinclair Spectrum, but I don't see it happening. Apple has ridden the crest of the technology wave and seen competitors' efforts mostly by glancing backward. It is because of their innovations that Apple has a large portion of the market share and will continue to maintain it without ever reducing their pricing. Apple doesn't discount its iProducts; it just makes new ones and charges the same. And there's no worms in that business model.
Getting great photographs of the world in motion is a difficult task. More than any other kind of photography, action photography demands lightning-quick reflexes, a solid foundation in composition and other photo elements, and a little bit of luck. However, anyone can learn to take great action photos if you're willing to invest the time and effort needed to understand the methods. Here are some techniques on how you can get started taking action photos.
Know Your Subject Matter
Because of the critical impact timing has on action photography, it is important that you understand what you are shooting. For example, with basketball, if you're not near the basket, you won't get a good picture of the next dunk. Take the time before your shoot to learn about how the activity you are documenting works so that you'll be able to anticipate what happens next and position yourself accordingly.
Get the Subject in Action
Try and capture your subject at the absolute peak moment of whatever that activity is. If you're taking shots of snowboarders jumping off a ramp, do you want the landing, the launch, or the highest point of the jump? Action photography is very striking when you are able to grab the most interesting part of the action, so make sure you're thinking about that before you shoot.
Focus in Advance
Many professional photographers will focus their cameras on an empty space where they expect something to happen. This is an easy thing to do if you know the activity you're shooting, and will save you valuable time when someone is flying through the air in your frame and you have milliseconds to react.
Pan with the Subject
It is important in action photography that you convey motion in the final print. While some subjects will have obvious motion, such as a basketball player frozen mid-dunk, others may require a bit of work on your part. Panning is moving the camera with your subject as they pass by. This will give you the end result of the subject being clearly in focus but the background being blurred by the motion of the camera.
Having the Right Film and Using a Flash
For action photography, a high speed film of 800 or above is usually best. High speed film will let you use faster shutter speeds in more varied light situations and help you to freeze actions perfectly. A flash can also be quite helpful in capturing those ultra-fast moments, though it is worth noting that the great majority of consumer level camera flashes won't have much use beyond 10 feet.
Continue the Action
If possible, try to avoid stopping the action of a subject in your picture. While freezing an action in progress is a good goal for an action shot, allow the viewer room to follow the action to a possible conclusion. For example if you have someone jumping down some stairs, position the subject near the top of the picture and have some stairs below so it's easier to understood the outcome of the action.
Action photography does take a lot of practice and patience and also used to take an enormous amount of film. Thanks to digital technology, now you can practice shooting without going through a lot of film and spending a lot of money refining your skill. And even better, many digital SLRs have continuous shooting modes that allow you to shoot 10-50 images in rapid succession so you can have more opportunities for the perfect shot.
The most important things in action photography are having fun and staying safe. You never want to get in a position where you could put yourself or someone else in harms way so try to only shoot in areas where photographers are expected and allowed. Beyond that, the more you shoot, the better you'll get!
