  • What's the vital photography equipment for beginners?

    Delving into the world of photography can be intimidating for a first timer. What type of camera should I buy? What else do I need? What is zoom? What is macro? Relax. Here's a quick guide to get you started.

    First, let's look at the camera. You can choose to go with either an SLR or point-and-shoot. Each camera has its benefits. Digital SLRs use interchangeable lenses that give you flexibility for different types of photography whereas point-and-shoots have fixed lenses and are generally easier to use (and less expensive). For example, an entry level SLR like the Nikon D3000, which includes an 18-55mm lens, will run you around $600 compared to a decent point-and-shoot like the Nikon Coolpix L110, which costs about $200. If you're looking for something for general picture-taking, a good point-and-shoot will suffice. If sports and action photography is more what you have in mind, you may want to spend the extra money on an SLR.

    Consider an additional lens if you do buy an SLR. Certain lenses allow you to take different types of photos. For instance, if taking landscapes is your forté, you might want a wide-angle lens [source: Sheffers]. Or you might be interested in a macro lens for close-ups of flowers or a telephoto zoom lens for capturing wildlife from a safe distance. Before spending that extra money, look at the capabilities of the lens that comes with your camera. You might be surprised at what your SLR can already do.

    You'll also need a memory card to store photos on. The cards depend on the camera you buy. Most point-and-shoots use Secure Digital cards, whereas SLRs tend to take CompactFlash. The larger the size, the more photos the card can store before you'll need to download them. If you plan on taking a lot of photos between each transfer to your computer, buy a card that's at least 2 GB.

    Other items you'll need are a camera bag, lens filters for an SLR and cleaning cloths. Find a bag with ample storage for what you plan to use with your camera. If you buy an SLR, get a bag with storage room for additional lenses. Filters will screen out UV light, which improves image quality, and they also protect the camera lens.

    Your final item may be a beginner's guide to photography. Two options are "Digital SLR Cameras & Photography for Dummies" by David. D. Busch or "How to Photograph Absolutely Everything" by Tom Ang. These types of books teach you how to use the various settings on cameras and how to get the most out of your photography.

  • What's a voice coil on a speaker?

    Sound waves travel through air pressure changes, and the sounds you hear differ depending on how frequent and how big those waves are. Microphones turn sound waves into electric signals, which is how you can record sound onto CDs and other devices. When you play the recorded sound, it's turned back into an electrical current. Speakers work like reverse microphones. They turn the electrical currents into physical vibrations that make the sound waves for your ears to pick up. When everything is tuned properly, the speaker is able to reproduce the vibrations that the original microphone recorded and changed into electrical signals.

    The voice coil component of a speaker is actually just an electromagnet. Electromagnets are coils of wire, and they're normally wrapped around some kind of magnetic metal, like iron. By running an electrical current through the wire, you produce a magnetic field surrounding the coil; this field magnetizes the metal in the middle creating north and south polar orientations. The difference between an electromagnet and a permanent magnet is that you can switch the polar orientations on an electromagnet by reversing the current's flow.

    Stereos use this property of electromagnets to repeatedly reverse the electrical flow. The amplifier switches the signal over and over, making the red output wire on the stereo switch between positive and negative charges. The voice coil's electromagnet is placed within a permanent magnetic field. The two magnets interact, and every time the electromagnet's polarity changes, the interaction between the magnets changes. When the magnets are repeatedly repelled and attracted, they move the coil back and forth quickly, kind of like the piston in an engine. The moving coil presses and pulls on the speaker cone and vibrates the air in front of the speaker. This creates sound waves via a driver that vibrates the diaphragm.

  • How to Choose a Digital Camera

    There are so many kinds of digital cameras out there that when you're ready to buy a new one, it's hard to know where to start. Here are some things to look at when choosing a digital camera.

    • Number of megapixels An image on a digital camera is made of thousands of tiny dots. A megapixel is a million pixels. The more megapixels your camera has, the better the resolution of your photographs will be. Most people don't need a camera with more than 6 megapixels
    • Type of camera There are different types of cameras on the market, from basic point-and-shoot cameras for taking pictures of family and friends to advanced cameras with lots of features for real photography buffs. A basic camera may cost between $70 and $500. An advanced camera will run you anywhere from $350 to $2000
    • Features Consider what features you want in a camera. These may include manual exposure settings and focus, zoom lens range, shooting, focus and flash modes, video and even 3-dimensional capability. Look at the lens quality, battery power and type of memory cards the different cameras use. Some "smart cameras" can set the exposure, focus and color balance, and can even detect smiles or warn you when a photo subject blinked in the shot
    • Brand Do some research to find out what brands and models consumers recommend. Different brands are known for selling cameras with different characteristics, so keep this in mind if you already know what type of camera you're looking for
    • Where to shop Consider shopping online, where you can find both a wide selection and low prices. Most stores only have one or the other. You may want to go into a store and try the cameras out before purchasing it over the Internet, though. Cameras have different idiosyncrasies that you wouldn't necessarily notice by just looking at a picture on a Web site
    • Price Of course you don't want to pay a small fortune for your camera, but beware of prices that seem extraordinarily low. This may be because the camera is refurbished or being sold on the gray market
