How do Polarized 3D Glasses work?
Polarized 3D Glasses
As a good example of stereoscopy, the polarized 3D glasses immediately creates the illusion of three-dimensional pictures by using filters to restrict light that normally would reach the eye. To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through orthogonal polarizing filters. All the viewer has to wear is a cheap pair of spectacles which contain a similar filters. The effect is managed due to the fact that light is only passed through each filter when it has been similarly polarized and has blocked the orhogonally polarized light

Polarized light rays bouncing off a cinema screen often get diffused and this de-polarization can be problematic. If an aluminized or silver screen is used, the situation can be resolved. This means that a pair of aligned DLP projectors, some polarizing filters, a silver screen, and a computer with a dual-head graphics card can be used to form a relatively low-cost In 2003 the value was under ten thousand US dollars. For people wearing polarized glasses this is the perfect system for displaying 3d data Several commercial and open source packages were made available thanks to the system GeoWall, used for some time now in the Earth Sciences.
Polarized 3D Glasses
To create a combined image, partially silvered mirrors with two image screens at right angles to each other should result in a practical stereo image that can be presented to a single user. Whilst you will be able to view one of these images as a reflection, you will be able to view the other directly through the angled mirror. Correctly adjusted glasses are equipped and filters, properly polarized, are attached to the image screens. A similar technique used with appropriate polarizer’s is to use a single screen viewed in a horizontal partial reflector,with an upright image placed below the reflector. Cathode ray screens are best suited to polarizing glasses, since LCD screens contain polarizers to control the presentation of pixels, and the polarization can conflict.
An economical application of this principle was discovered in 2003 by Keigo Iizuka, using cellophane sheets on laptop display screens. Polarized stereoscopic pictures first came about in 1936, when Edwin H. Land first applied it to motion pictures. 1952 through 1955 was when the “3-D madness” hit most theatres ,offering patrons 3-D glasses. Only a minute amount of the total 3D films shown in the period used the anaglyph color filter method. The novel aspect is their use of digital projection and high-tech IMAX 70mm film projectors, with extremely trustworthy mechanical parts. Using varying forms of polarization, a completely new chronicle of 3D animation films are now beginning to reveal themselves to theaters. Polarization is not easily applied to home 3-D broadcast or DVD presentation. At this point only anaglyph glasses may be used to view the new HD shows and are beginning to be aired occasionally by NBC and the Discovery Channel.

It’s amazing what a box office success can do to a person’s preferences for Halloween. The Batman Dark Knight made one of the biggest impacts in movie history earlier this year and while the caped crusader commanded center stage, we’re not sure he stole the limelight.

That’s why the Joker Halloween mask look is going to be very popular. In fact, while good triumphs over evil, did Batman really beat the Joker in the popularity stakes? Did the performance of Heath Ledger give the Joker a moral victory?

What a great talking point at your fancy dress party this year. Imagine turning up in a Joker Halloween mask and spotting the Batman surrounded by a throng of adoring fans. Pose the question…”Hey Batman…you may have taken the points but who gained a fan club.”

It’s weird isn’t it. Developing a following for a dark and twisted character like the Joker but such is the nature of Halloween. People get the chance to join a realm of the supernatural and compare costumes with friends.

More Than Joker Halloween Masks

Of course it is important to note that there are more than just masks and costumes available for the Joker from the Dark Knight movie. There have been other movies as well that included the Joker in them played by a different character. So, you’ll find that there are various Joker masks out there that you can choose from this Halloween.

Once you have your mask, you’ll find that you are just about set for a Halloween party or for going out trick-or-treating. You don’t really have to purchase the rest of the costume. Just start mixing and matching some of the clothes in your own close for an eccentric look, and you’ll have a great costume that is unique.

If you are keen to accentuate the look then adding some hair to the mask will set off the look even more. Some masks come with the hair as well but may be harder to locate. You can go with an unruly wig or even a smooth parted down the middle wig as well. If you can do this with your own hair, go for it, but you may need a special wig to pull it off.

As you can see, going with a Joker Halloween mask is definitely a great idea. These masks are very easy to find, there are several styles to choose from, and they are relatively inexpensive as well. So, if you are looking for a great costume for Halloween, which is coming up quickly, this may be a great choice that you want to consider for this year.

One of my favorite past time is reading pocketbooks. I like books that thrills me such as horror or action packed books. My favorite book is “The Bourne Identity” a 1980 spy fiction thriller novel by Robert Ludlum. The story is about a Protagonist who had an amnesia and who must discover who he is and why several groups, including an assassin and the CIA, are trying to kill him. It is the first in a series of novels written by Ludlum, and later became a movie but I like reading the book better than watching the movie.
Usually in movies there are scenes that have been cut to make it shorter because of the fact that the story in the book is quite long and most often movie characters are hard to find. That is why most probably there is a small difference in the physical appearance of a certain person in the movie compared to the book. Reading books for me is much more interesting than watching the movie itself. Specially when I start putting my Titanium Reading Glasses on I seem to feel the environment of the books that i am trying to read and let my thoughts go wild which I prefer more than just sit and relax while watching the movies.
What I like most about books about espionage is the fact that it plays with your mind making your mind think and suddenly makes a twist in every part of the story which really might be confusing but a little exciting.
Espionage is well documented throughout history. It is a military art of obtaining intelligence from the enemy. In History Chinese and Indian military strategists such as Sun-Tzu and Chanakya contain information on deception and subversion. Mostly stories like this would be about assassinations, spies and secret agents which makes the story really exciting. In Feudal Japan they often used ninja to gather intelligence later on as technology starts to evolve modern espionage methods has been developed. From shurikens and samurais to high tech gadgets and satellites similar to a Magnifying Glass function however it could magnify any part of the world more than a thousand times.
Spies are hard to identify unlike criminals whose looks has an intention of killing they can look ordinary and can be anybody around you. A newspaper boy, a driver, a saleslady or an old man with a Wide Reading Glasses extracting information from anyone. Well then I think I’ve shared too much information about them I hope there are no spies around I might get killed. I should continue my reading.

3D Glasses - How Do They Work?
The Science of 3D Glasses
3D Glasses
Most human beings have fantastic binocular vision, thanks to having two healthy, working eyes. Objects can appear up to twenty feet. 6 thru 7 meters at a distance, the binocular system of vision allows us to gauge effortlessy and precisely the distance to an object. As an example, when we see multiple objects, we are able to automatically distinguish those that are nearer from those that are farther, and how far away they are. Looking at the world with one eye closed will still allow you to perceive distance; however, your accuracy will decrease because you must rely on visual cues for focusing distances.

To see how much of a difference the binocular vision system makes, have a friend throw you a ball and try to catch it while keeping one eye closed. The differences become more obvious when tried in a darkened room or at night. If you only have one eye open, it will be much more difficult to catch a ball than if you have two open.
Anaglyph 3D Glasses
The binocular system of vision depends on the fact that our pair of eyes are located approximately two inches at a distance. (just over an inch) separately. The binocular vision system works since the brain is able to utilize the different perspective obtained from each eye and process them together to calculate distance. The brain possesses the capability to connect the images seen through the two eyes even if they are somewhat unlike. The correlator can pick out objects in the two scenes it sees and calculate how far apart an object is between the two images. Objects that are farther apart in the two images are closer than objects that are not so far separately.

You have seen the binocular vision system at work if you have looked through a View-Master or stereoscopic viewer. The way a View-Master works is that an image is shown to both eyes. The image is created by two different cameras photographing the same image from different angles. Your eyes can correlate these images automatically because each eye sees only one of the images.

The High School Musical Movie, another Disney production which is a complete success when it was released for the cable channel a few years ago. In his sequel production of the HSM movie franchise, Sharpay Evans (played once again by Ashley Tisdale) convinces the club manager Mr. Fulton to hire Troy Bolton for the summer. Sharpay figured having Troy work for the golf club where her the family devoted their summer escapade (her parents seat on the board of the club), will mean the perfect opportunity to catch his attention and his heart. Sharpay cant believe that she still has to share Troy Bolton with Gabriela and the entire East High basketball team during her almost perfect summer! Sharpay successfully confuses Troy and alienates him from his friends but in the process loses the respect of her beloved brother Ryan. This time Sharpay and Ryan work separately as Sharpay has managed to convince Troy to sing with her.

If you are planning to save your digital photos to disc, it is a smart move to buy dvds instead of cds. DVDs generally have more room, which means that you can save more photos on one DVD than on one CD. Additionally, many DVDs can be viewed on a computer or DVD player. If you want to show your vacation or family photos at the next family reunion, you can leave those heavy albums at home and bring your DVDs instead!

Music to DVD - What a Combo

I have loved music since I was a little girl. I would wake up to the sound of my Mother singing along to Frank Sinatra or Barbara Streisand on the radio while she cooked our breakfast. Now as a Mother of two teenagers, I find myself singing along to whatever DVD I have just popped into the DVD player. Over the years I have amassed a large collection. The love of music in this family has now, of course, continued on to my daughters. They burn or buy dvd every chance they get. Music is as big a part of their lives as it has been to my Mom and me.

We got a little extra cash this weekend so I decided to use the money to go to a movie store to buy dvds. I got some really good movies at a reasonable price. I got a mixture of new and used movies. Some of them I’d seen and some of them I picked up because they looked interesting. I guess we know what I’ll be doing this weekend – checking out all the new movies I picked up!

What is DVD?

In case you’ve lived under a rock and don’t know what DVD is, here’s a little primer for you. DVD is an abbreviation for “Digital Versatile Disc”. DVD is a digital video presentation format that reached market acceptance in the mid 1990’s. It was seen as a successor to the earlier laser disc formats and slowly replaced magnetic video tape (VHS) as the dominant home-video format by 2000. DVD discs measure the same dimensions as CD-ROM discs that are used in computers, but have the capability of storing video and audio material as opposed to the former. Further along, blu ray dvd is a newer high definition format for movies.

Should You switch to DVD?

One of the main enticements that was originally used to convince people to switch from VHS to DVD was the possibility of providing supplemental content (featurettes, interviews, etc.) along with the actual movie or television program. On VHS tapes, of course, these could only be providing linearly, before or after the program, making them more troublesome to view. So in most people’s minds this was a plus. However, it has now gotten to the point where if a DVD doesn’t contain any “special features”, people are less likely to be interested in it, and as a result, some DVD manufacturers will list things like subtitles and widescreen/fullscreen options under “Special Features” just to be able to fill in that space.

Fill out your collection

People who want to fill out their DVD collections can sometimes be scared by the sheer quantity available for purchase as you can buy dvd movies pretty much anywhere. As a result, you’d be wize to come up with a guiding principle to organize a collection before going out to buy DVDs. Some people expand their collections by systematically buying DVDs which feature favorite directors. Others focus on particular genres, such as foreign films or classic films. Still others collect DVDs that remind them of certain favorite times in their lives. However a collection is focused, it’s important to prioritize which DVDs should be added first. A well-organized, well-thought-out collection can impress friends by its mere presence on the shelf, since it becomes a reflection of the collector’s tastes and personality.

The Iron Man movie exploded on to the movie screen in 2008 with avengeance. When a movie makes over $300 million you have to stand up and take notice.

For both comic book fans and others who wouldn’t go near the, the Iron Man Blue ray manages to strike a perfect cord with watchers. Robert Downey Jr plays the role of Tony Stark, a multi-billionaire genius and self-proclaimed playboy that puts as much effect into the ladies as he does chasing his next big idea. However while traveling overseas Stark quick jumps into chaos as he finds himself at the mercy of a power hungry warlord.

The positive reviews by today’s critics are hard to miss. The gadgetry is absolutely dazzling, the action is mostly exhilarating, the comedy is scintillating and the whole enterprise throbs with cinematic energy. Iron Man Blue ray is an action science fiction blockbuster extravaganza that provides cartoon thrills for thinking people. It’s the best movie of its kind since the second Spidy movie four years ago.

However not everything in this movie is perfect, as critics have pointed out a few problems with Iron Man. Switching between Tony’s impish goatee and Iron Man’s full-metal body suit, and amid so many generic fireballs, kill shots and earsplitting thumps, bumps and crunches, the film finally collapses under its own weight. Downey’s unbeatable charisma makes these problems less troublesome than they would be otherwise, but wouldn’t it be nice if they didn’t exist at all.

The value of the Iron Man Blu-ray is hard to pass up. The package includes deleted and extended scenes, a 7 part making of documentary, another 6 part “invincible iron man” documentary, visual effects and a Bob Downey screen test. The Blu-ray version contains special exclusives as well in a featurette entitled, Hall of Armor, IM IQ and more.

Director Jon Favreau and star Robert Downey make this smart, high impact superhero movie one that even non-comics fans can enjoy. At the end of the day it’s Robert Downey Jr. who powers the lift-off separating this from most other superhero movies.

Want to get a more unique look this Halloween? How about a Princess Fiona costume? What, who is Princess Fiona? Remember the Shrek movies?

Enough questions, let’s tell you why a Princess Fiona costume will be the perfect choice for you this Halloween. Quite simply, she was no ordinary princess. Most princesses in fairy tales were meek and mild and although beautiful, they always needed a prince to come along and defend them against evil.

Not so Princess Fiona! This little miss had the high kick of Chuck Norris and Jet Li rolled into one and could take down a band of villains in the blink of an eye. She was just the perfect companion for the big fella Shrek and to be honest, he would have been the only one who could have fended her off when she lost her cool.

A Princess Fiona costume really does encanpture what Halloween is all about. It’s about ghouls and goblins, witches, things horrific but it’s beautifully balanced out by the mystical and magical aspect of the fairytale and that’s what the Shrek adventure is all about.

What Was Princess Fiona’s Secret?

Princess Fiona laden with a curse which she kept a secret but after teaming up reluctantly with the ogre Shrek and his side kick donkey, she eventually discovers the curse was more of a blessing as her romance with the ogre develops.

Originally, Princess Fiona expected her Prince Charming to come and rescue her and when Shrek showed up instead she was none too pleased. Their relationship was cold at first but as she got to know the big fella, she started to realize he was just a big puppy with a real soft spot.

The fairytale happens when both Fiona and Shrek eventually discover that they had more in common than they first thought. It all had to do with Fiona’s curse which would you believe, allowed her to be a human by day yet when sunset came, she turned into an ogress!

Shrek The Romantic

It just goes to prove that there is someone for everyone in this world. Shrek was an ogre who was perceived as mean and liked to be alone. Yet just as Belle was able to tame the beast in Beauty And The Beast, Princess Fiona was also able to pierce the tough exterior of Shrek and reach the heart we always knew he had.

So do you look for a Princess Fiona costume for Halloween in her human form or do you look for the ogress model.

Our tip is to go for the human version and get your partner to dress up as Shrek. Just seems more effective and besides, it will be a great starting point for conversation at your Halloween party.

Are you wondering if you should succumb to the Blu Ray technology, or just stick with your old DVD player? The answer depends on how big a movie buff you are, really. If you’re the kind of person who watches movies every week or every couple weeks and loves that home theater, high-definition, surround-sound experience, then a Blu Ray disc player is in your near future. However, if you were reluctant to dispose of your old VCR, you prefer going out to the movies, or you consider yourself to be extremely frugal, then you might choose to enjoy a friend’s Blu Ray movies instead.

Blu Ray (BR) is the new format developed for optimal recording, rewriting, playing and storing of high-definition video. The world first learned about the new technology with the release of Sony’s Playstation 3 in November 2006. To make more advanced games, Sony needed a way to “fit in” more data. While the DVDs in your current collection hold 9 GB of information, the Blu Ray discs are able to hold 25-50 GB, making it five times more efficient! Manufacturers like Sony, Panasonic, Pioneer, Philips, Samsung, Sharp and JVC (to name a few) are using a different type of laser (blue versus the traditional red) to pack more data with better precision.

When 5.0 Surround Sound first came out, it revolutionized how we heard movies and music. Blu Ray features 7.0 Surround Sound for more bumps, shouts and vibrations than ever before. Likewise, the picture quality is said to be six times better than a regular HD-DVD. The good news is that old CDs and DVDs will still work on the Blu Ray players, although all new movie releases will only work on the new Blu Ray players.

So just how popular is the Blu Ray? It’s so popular that market analysts are speculating that Sony may not have the capacity to tackle the demand for the new media! The demand is said to be around 43 million units worldwide, but factories can only handle production for 38 million, and that’s after an upgrade to their facilities. Therefore, you can expect prices to remain high until the supply side catches up with the demand. Prices on the initial players range from $400 to $1,000 but the subsequent versions are expected to be offered for around $300.
