Basics of the Digital camera

Like most things in life when your experiencing something for the first time you are often unsure how to go about it. The same can be true when buying your first digital camera. You will undoubtedly be inundated with facts, figure and more jargon than you know what to do with. We will attempt in this article to help you along with some of the jargon and show you what to look for when buying a digital camera. Some of the feature may not interest you unless you need your camera to perform specific tasks, however its always worth knowing exactly what you are buying so you can pick a good deal when you see one.

<b>Megapixels</b>

The resolution of a camera is measured and advertised in megapixels. The idea behind this figure is the number of pixels that the camera has to take an image with. In this case the higher the number the better quality of picture you will be able to take. For example if you purchase a camera that has a resolution of 4 Megapixels, pictures that you take with that camera will be able to take images made up of 4 million pixels. Its obvious when you think about that a camera with a 2 megapixel resolution will not create as image as crisp or as detailed as the 4 megapixel one.

If you often print out your images on your PC or have them sent away to be printed then the megapixel rating of your camera can be very important to you. Higher megapixels on your camera will allow you to make prints larger in size while still keeping the quality. If you try to print a picture too large than what you camera was designed for then the image drastically loses quality.

The last thing to know about megapixels is the higher the resolution you take pictures in the more space on your memory card will be taken up. A picture taken on a 4 megapixel camera will need twice as much space on a memory card as a picture taken on a 2 megapixel camera. Be sure if you want quality pictures have enough memory on your camera to back it up., Either that or have spare media cards to plug in once your space has been used up.

<b>Digital Zoom and Optical Zoom</b>

No doubt when you are buying a camera you will want some sort of zoom function to take those in the distance shots. This is a troublesome area for some first time buyers. There are two types of zoom on the market for digital cameras. Digital Zoom and Optical Zoom. The only one that really matters is Optical zoom, this is true a true zoom function that brings the objects closer to you using the optics of the camera. Digital Zoom is like using the zoom function on an image editing software package. It enlarges a section of the image so it looks as if its closer to you.

Anything you can do with digital zoom you can do with a photo editing package so don't splash too much money on a camera with digital zoom only. Sometimes you will also so "total zoom" advertised this means the number that is quoted here is the optical zooms magnification added to the digital zooms magnification. Try to find out the magnification level of the optical zoom alone for the true value of the camera.

<b>Aperture Size</b>

We may be going a little further here than some of you would like to care about but bear with us as the aperture size can make a big impact on your pictures. The size of the aperture determines exactly how much light is let into the camera when your picture is taken. Think of the aperture like the iris of your eye. No big deal you may think, however having more light allows you take better pictures in a variety of lighting condition, cloudy days is a perfect example.
With a large enough aperture you would be less likely to need the flash, personally I don't like to use the flash function, the artificial flash of light does not always do justice to the picture you are trying to take. Also effects like red eye are also common.

<b>Shutter Speed</b>

Great effects can be made to images using a variety of shutter speeds. The thing to look for when buying a decent digital camera in terms of shutter speeds is the broadest range you can find. This will give you the best chance of manipulating the picture the way you want it. Combined with a pro-active aperture the shutter speed can make pictures come to life or freeze images in an instant.

This technique is great when you want to take moving objects exactly how they look as if they were still. Setting the shutter speed on a slower setting gives more exposure to the CCD (charge coupled device - the digital equivalent of film). The effect is that the picture almost seems to run. Moving objects are slightly blurred. You may think this is a bad thing but take an example of running water leaving the shutter speed on for longer will soften the image creating a pleasing image to the eye much like the way a waterfall appears in real life.

You can take digital photography to the extreme with a camera that has a very wide range of shutter speeds. With an incredibly slow shutter speed, you can have a long exposure of light to the CCD and hence receive like the famous traffic scenes where the headlights blend into each other into a constant stream.

<b>Storage Media</b>

Digital Cameras come with a slot for a variety of media cards. Check when you buy your camera what type of storage media it requires. There are several popular types including Smart Media, compact flash and xD picture cards. As long as you know what type your is you should be able to safely by the correct type. Always ask at your local store if you are unsure. If you give them your make and model they should be able to point you in the right direction.

The size of the media card you choose depends on your budget but get as much as you can afford. More memory means that you don't have to change media cards, and you will be able to take pictures in the highest quality all the time. You will soon learn the benefits of having plenty storage space when you start to use your camera regularly.

The good thing about cameras media is that its just like a film if you do run out you can simply insert another one if you have one with you. It can be a bit of a pain when downloading your pictures to your PC but much less more of a pain than having to delete some picture because you have run of space on your media card.

Do You Download Music Over A File-Sharing Network?

It can be estimated that millions of people around the world share music over a file-sharing network. For this article, I am addressing the issue in America mainly because I am not aware of the laws in other countries. Do you think it is illegal to download music from file-sharing networks? What about music you already own? An important recent court decision will answer these questions directly and you might be surprised.

Recently the United States Court of Appeals for the Seventh Circuit heard a case against a Chicago woman, Cecilia Gonzalez. Many plaintiffs including BMG, Sony and others brought the case against her. Gonzalez allegedly had downloaded over 1,000 songs through KaZaA—although she admitted to only 30. Keep that number in mind, 30. Many, if not just about all, people who download files over a file-sharing network don’t stop at one file. Thirty files can be reached in minutes to an hour without thought. In fact, it was alleged that Gonzalez downloaded 1,370 songs in just a few weeks, which is an average of 65 songs per day.

If you where caught downloading thirty songs over a file-sharing network, what would your defense be? Let’s look at two specific common defenses and see how a court might react. I have selected two defenses that I feel are most common, because they not only appear in the court case I have referenced, but many others I have surveyed would try to use them as their defense as well.

First Defense: I was simply trying out the songs to see if I liked them and then I planned to buy the ones I liked and erase the ones I don’t. (Simplified: try-before-you-buy)

Judge Eastbrook, one of the judges hearing the Gonzalez case, pointed out that this defense is not valid because one had many avenues to hear music before purchasing. Eastbrook names iTunes, radio, internet radio, Yahoo! Music and others as ways to legally try before buying. If this was going to be your defense, you will lose.

Second Defense: I am only downloading music that I already own.

This seems like a great defense, at first. You already own the music and the law allows you to create a backup copy. Ah, but here is where it goes south. Downloading music you already own is not considered fair use under the U.S. Copyright Law and your action is therefore copyright infringement. See UMG Recordings Inc. v. MP3.com, Inc., 92 F. Supp. 2d 349.

Furthermore, the try-before-you-buy scenario is really blown away by the fact that you no longer need to buy CD’s in whole. iTunes really helped change the legal arena in this respect because a user can both sample songs at their leisure and purchase single songs. The ability to purchase single songs is the big one.

In the end, Gonzalez lost her case. The thirty songs, that would have cost $29.70 at iTunes, will end up costing her $22,500 in damages—imagine what it would be if the plaintiffs had pushed for a decision on all 1,370 songs. She was given the opportunity to settle for $3,500 before going to court, which she declined—another bad decision. If you download music over file-sharing networks and are caught, what will be your legal defense?

Black Christmas movie review

This festive fright-fest was a nice surprise from what I was originally expecting. This is another horror remake (from the people behind ‘Final Destination’ – great film), but un-like so many others; it did manage to come up trumps; such as ‘The Texas Chainsaw Massacre.’ This is a remake of Bob Clarke’s 1974 classic slasher movie, ‘Black Christmas’; which actually came four years before John Carpenter’s ‘Halloween’. Some fans lay claim that it was the original slasher flick.

From the outside, this looks like just another of your basic ‘there’s a psycho hacking up a bunch of pretty girls, who are running up the stairs instead of out of the door,’ and to a certain extent that’s correct, it’s the way this is conveyed which is interesting and enticing to watch.

The story: crazed killer, Billy Lenz, escapes his psychiatric ward and is determined to make it to his childhood home, where he was abused, by Christmas. Problem is, it’s years later and the home is now a Sorority house. It’s Christmas Eve and a who’s who of teen/horror girl stars are there to welcome him, including Melissa (Michelle Trachtenberg , ‘Buffy the vampire slayer’ fame), Heather (Mary Elizabeth Winstead, ‘Final Destination 3’), Dana (Lacey Chabert, ‘Mean Girls’) and Kelli (Katie Cassidy, ‘When a stranger calls’ remake.)

This movie is actually pretty good, it has a constant feeling of being watched that runs right through it and adds a sparkle to the scares, and the tension is kept high. The actresses, although spouting some awful lines at times, also say some good ones. The acting is good, and because most of the leading ladies are stars, and most of them horror stars, the audience doesn’t guess which one is going to make it to the rolling credits. The story-line builds well, and there is a mounting tension, as the killer first phones the girls, and then starts to do away with them.

A similar storyline to the original ‘Halloween’, with a killer coming home for the holidays, there are also many similar P.O.V shots of the killer, watching the girls throughout the house. The Christmas theme bleeds in nicely with the plot, and it comes across in places (especially, the flash-backs to Billy Lenz’s childhood) like something, director, Tim Burton, would dream up. The film gets darker and darker as we move through it, with some very violent scenes, and the music by Shirley Walker is great; capturing horror and Christmas all in one twisted melody. Also, the use of red and green lighting throughout (owed to Christmas) is very cool, and creates a great atmosphere.

Due to it being set in a Sorority house, and this no longer being 1974, some of the dialogue just doesn’t cut it. I can’t imagine many of these girls’ staying in the house with a crazed serial killer, just because they can’t find their ‘sorority sister,’ believable in 2007 – sad, but true. There is, unfortunately, the obligatory shower scene, but it’s used for scares, not thrills, and so works.

Right from the start you can tell, this isn’t your usual run of the mill slasher, it actually has a back story, and we do find ourselves caring for some of the characters, for example, Kelli, played by Katie Cassidy is great; plus if you hated ‘Dawn’ in ‘Buffy the vampire slayer’ – you are gonna love this movie.
