Finding The Best Small Digital Camera

Digital cameras are getting smaller and smaller every year. People seem to have a fascination for very compact gadgets. Remember how bulky mobile phones used to be?

Now they have models that are small.

Since digital cameras are one of the most popular portable devices on the market, a lot of people are looking for the smallest digital camera they can find. If you find yourself scouring the internet and your local electronics stores with that goal, just keep in mind that one way to reduce the size of a digital camera is to include fewer features. Don’t sacrifice important features just for a smaller size.

After all, what good is a small digital camera if it only has enough memory to store a few shots, or if it is a low-resolution camera that produces grainy photos?

You need to find the right balance. Find the right trade-off between small size and the important features. Let’s compare some of the smallest models to illustrate.

– The Blink by StyleCam is, technically speaking, the smallest digital camera available today, but it only has a resolution of 0.3 megapixel. It’s not built for serious photography. It also doesn’t have any zoom function to speak of, but at a price of less than $40, it could be considered a good value digital camera.

– Sony’s CyberShot DSC-U20 can also compete for the title of the smallest digital camera, but it’s loaded with features to boot! It comes with a 2.0 megapixel resolution and expandable memory storage using Sony’s memory stick technology.

– Casio’s Exilim EX-M2 is probably the best investment when it comes to compact digital cameras. It also comes with a 2.0 megapixel resolution, but it can also play mp3 files and record voice conversations. The only thing going against the Casio Exilim EX-M2 is a price tag of almost $400.

Just because we’re looking at the smallest digital cameras doesn’t mean that they will also be the cheapest models. It can be expensive to shrink the best features into a tinier package. It also doesn’t mean that we should settle for fewer features. Our investment can go a long, long way as long as we exercise a little caution and do a fair amount of research before making our choice of digital camera.

How To Secure Your Home With Surveillance Cameras

Securing your home in case of emergencies such as thieves and other intruders is a good idea, no matter whether you live in a stand alone home or an apartment. One of the easiest ways to protect your premises is to use surveillance cameras, strategically placed around your home based on the amount of space you have. These systems can be purchased with as many cameras as you might need, and are available in wireless or wired formats.

For most home surveillance equipment users, wireless models will be the way to go. They are easy to hook up and easy to mount, and you will cut down on the amount of floor space used by tangle-prone wires. The signal for wireless cameras will be sent to a receiver, which will be hooked up to whatever equipment you are using to monitor the premises.

How many cameras you buy will depend, of course, on the size of your home or if you have anything of particular value in a specific room. If you want maximum security, you will want to mount cameras on the entrances to your living space, including the windows, as well as the garage and driveway, at a minimum. Additional rooms containing valuable equipment or pieces of furniture should also have a mounted camera for added security.

All the security cameras in the world are useless, of course, without a monitoring system. You need to decide if your security camera system is to be utilized in the prevention of theft or to assist in the recovery of property. Most thieves and other criminals will be deterred by the mere sight of a camera on the premises, despite movie depictions of crack shot take-outs of security cameras. The mere presence of the camera, then may serve to protect your home.

If maximum security is what you require, then you or someone you know will need to be monitoring your system throughout the day. Larger homes of wealthy families may be able to employ security guards around the clock, but for most the purpose of the surveillance equipment will be to aid in recovery. Make sure that your monitoring equipment is always on and that you either reset the tape manually or have the system set to reset itself.

Home surveillance equipment can do nothing to prevent loss of property on its own. Without proper utilization and monitoring, your surveillance equipment is only a drain on your resources. Take the time to install your cameras properly, checking to make sure they cover all of the points of entry or objects you want watched to a high degree in terms of parameters. Cameras which track motion or otherwise can swing to encompass a wide area are great options, although they may give the location of the camera away. Again, however, it is important to remember that most ne’er do wells will be deterred from their sinister purposes towards your property by simply being aware that the cameras are there.

Digital Cameras: Quality Vs Size

When looking to purchase a new digital camera there is always the debate between size and quality within the range of your budget. No matter what the budget, the choice will have to be made between a smaller size, more portable camera and a higher resolution camera with more features. Making the choice between the two is simply a matter off considering what the camera’s purpose.

Digital camera users who plan to use a camera for simple point-and-shoot purposes will want to focus their budget on a small, portable camera. These individuals are most likely using their camera to document travels, family events, and personal experiences for their own memory. The photos don’t need to be or a super high resolution because they will not be blown up to poster size, but will remain 4 x 6 or 5 x 7 in a frame on the mantel. It is important to consider that when size is traded for quality, while the photos will be higher quality, users may be less inclined to take photos as the size of the camera becomes a hindrance to taking it.

Photographers who are more interested in the end product will want to sacrifice size for a higher resolution camera or one with more features and/or accessories. The bulkier high-resolution cameras or digital SLRs will be the better choice for users who are taking professional photographs. Even the amateur, will want to invest in quality over size to produce the kind of photos that can be enlarged to show detail. Cameras used for professional shots, whether to be displayed in a portfolio, brochure or website, will also need to be of higher quality, and it will be worth hefting the extra weight to get the higher-end photos.

Knowing the type of photographer you are, will help you make the right choice in cameras. When you have an idea of what characteristics are most important to you, take the time to shop, read the reviews, and compare the various cameras in your price range.

Defining The World Of Security Cameras

Finding the right security camera is difficult enough without having to wade through the terms and figure what the abbreviations and words actually mean. If you’re trying to do research on a security camera and frustrated with the multitude of terms that are unknown to the average user, here’s a list of the terms you’ll want to know. There are many more out there, but this is enough to get you started:

DVR: Digital Video Recorder, or ‘personal video recorder.’ Usually used when referring to a Security Camera System, you use a DVR to record broadcasts on a hard disk drive which can then be played back at a later time. The most well-known type of DVR is TiVO. They often come with standard features like motion detection, time and date stamping, and remote internet monitoring capabilities.

Motion Detection: Many cameras and DVRs are built with motion sensors to track movement securely.

Time and Date Stamping: Term used when a DVR records the date and time of an occurrence or recording.

Remote Internet Monitoring: Refers to using a camera like a Network IP Camera to record information and the ability to see that information live in real time from a distant location.

PC: Still refers to a personal computer.

PTZ: ‘Pan, Tilt, Zoom’ refers to the motion of a controllable or PTZ camera. Movement can go from left to right and up down, as well as zoom in and out on an object.

Infrared: A technology that uses heat sensors to detect objects in its surroundings. It was developed especially to ‘see’ in the dark.

Network IP Camera: refers to a type of camera that connects to the internet or a computer network via an IP address and can be viewed remotely from different locations.

DVR Card: Digital Recorder Card. Provides digital video recording capability so that you can store video files from your security/surveillance system on your PC.

Camera Housing: Refers to the outer shell of a security camera. It serves to weatherproof, protect, and ‘house’ the camera from potential harm.

Quad Processor: four processors in one

Multiplexer: the multiplexer takes several separate digital data streams and combines them together into one data stream of a higher data rate. A multiplexer makes it easier to combine the data from several security cameras into one stream of information. This is system is a quicker and more effective way of processing information.

Multiple Output Power adaptor: a power adaptor that enables multiple outputs and is highly useful for a system that requires a good amount of power.

Security Camera Systems: General, broad term for the package that security companies often sell. They are usually a better deal than buying the items separately and come in a variety of choices. They usually include a security camera, Processor, Software, Cables, Power Adaptor, Monitor, VCR/DVR, and some come with a warrantee. This is one of the more basic kits; more deluxe options often entail other accessories.

Dome Security Cameras: Dome security cameras are ideal for use in building entrances, stores, and shopping malls; in short, anywhere you want a ‘fashionable’ camera that is designed to blend into its surrounding environment. Prettier and more appealing than its cousins, a Dome Camera offers high security and an increased surveillance capacity because of its non-invasive qualities.

PTZ (Pan, Tilt, Zoom) and Controllable Cameras: PTZ and Controllable Cameras are designed to be controlled by remote or through a DVR. They have the ability to move up and down as well as right and left. You can pan, tilt, and zoom in or out. You have all the control you want over these cameras, and they provide excellent surveillance and security.

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. This article will attempt 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.

Megapixels

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.

Digital Zoom and Optical Zoom

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.

Aperture Size

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, 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.

Shutter Speed

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.

Storage Media

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 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.

7 Simple Reasons Why You Need A Network Security Camera For Your Home

Pros

1. Easy to install: Most of the network cameras on the market are plug and play and/or have very simple to follow instructions for both the hardware and software end.

2. Comparatively cheaper than other security systems: Instead of paying a highly trained technician to install a complex CCTV system, and pay him on an ongoing maintenance arrangement- you can have a network camera security system that can stand on it’s own against CCTV and traditional security systems.

3. Works with your existing computer network: If you already have a home network, then the network camera works with your settings, so you don’t need to pay more for the proper security infrastructure.

4. Provides peace of mind: watch your home, watch your childs room, watch your vacation home, watch your cats while you are on vacation, etc

5. See remote areas: as far away as across the globe, or your own front porch from a centralized area. Can even remotely view your children at the nursery (depending on the nurseries policies though this is becoming more standard)

6. Flexibility: Prefer not to be tethered to the security control panel or hire a full time security professional to monitor things, then get security alerts which you can view from cell phone, laptop, or PDA device, and provide multiple users access to the various security assets.

7. Receive alerts via email when detects motion, either when someone visits your home, or when your children leave home to hang out.

Cons

1. May have poor image quality depending on model and configuration, and wireless cameras in general have poorer image quality on the lower to mid range.

2. For more bells and whistles, like sound recording, scheduled emails, and motion capture, it varies greatly from model and software description.

3. Generally, outdoor surveillance equipment is more costly, especially if you want the ability to remotely pan/tilt, zoom in, zoom out, and want a waterproof camera. However for a home system this is probably not as urgent as opposed to for a business situation.

4. Drains computer network resources, so if you don’t have a speedy computer, then there’s a chance of a slight slow down in your collective resources.

Remember that despite the cons, the benefits outweigh them as they provide great security results at a lower installation and maintenance cost than traditional Closed Circuit Television systems.

Purchasing Digital Camera Batteries

The advent of digital technology has greatly changed the way consumers use products. Digital cameras are one product that has shifted behavior and production. Digital camera batteries vary by brand and model, and also by the type of battery.

There are literally dozens of digital camera brands. Before finding the right digital camera battery and adapter for your camera, you need to be sure of the brand and model digital camera you are using. Once you select the brand, there are numerous model numbers to choose from and these batteries are typically not compatible across model numbers. Manufacturers design a specific battery technology for each model that provides optimum functionality for that specific digital camera.

Digital camera batteries can vary greatly by price depending on the type of battery you purchase. Traditional alkaline batteries are far less expensive than newer technology batteries, but do not last as long and do not have as much power. In order to keep up with the fast pace of digital cameras, manufacturers have created Lithium batteries. Lithium batteries last up to 10 times longer than alkaline batteries, and therefore can take many more pictures. Though lithium batteries last so much longer, they weigh much less than alkaline batteries. For the convenience however, lithium batteries are much more expensive than alkaline batteries. Another inexpensive alternative to lithium batteries is oxy-nickel batteries. There are specifically designed for digital cameras and last up to four times longer than alkaline batteries.

There are lots of things to take into consideration when purchasing a digital camera, but batteries aren’t usually one of those things, though they should be. Batteries are one of the only supplies for a digital camera that will need to be bought on a regular basis. Unlike conventional cameras, you never need film for a digital camera. But if you want to store these photos without a computer, you will need memory cards that can store large files like the images taken with a digital camera.

Buying the best digital camera battery is the best way to get the most out of a digital camera. By buying quality batteries, you will be able to take more pictures without delays and also save money in the long run.

Types of Digital Camera

Digital Cameras

Sales of digital cameras seem to be exploding. This is not surprising as the quality of images from digital cameras improves and they become more affordable. In addition, consumers are becoming more comfortable with the idea of digital photography.

There are so many different types of digital cameras available choosing one which is best for your needs can become a very confusing decision. There are several things to consider when choosing a digital camera.

Also Check: Digital Camera Care

Types of Digital Camera.

There are basically three types of cameras whether you care shooting film or digital. Point and Shoot cameras, Prosumer cameras and professional quality cameras.

1. Point and Shoot cameras are fully automatic. They do everything for you. The camera choosing the correct exposure and whether a flash is needed. The photographer only needs to point and shoot.

2. Prosumer Cameras. These cameras are a step up from point and shoot cameras and allow the user to either shoot in fully automatic mode or to have some control over the exposure by using specific exposure modes. For example, there might be a portrait mode, an action mode, and a close up mode.

3. Professional Cameras. These cameras allow the photographer to actually look through the lens. This means that what you see is what you get. These cameras also provide complete control over the exposure. They have fully automatic mode, specific exposure modes as well as a fully manual mode.

Resolution

Regardless of what type of camera you decide to get you will also have to make the decision about the resolution of the camera.

If you have shopped at one of those electronics superstores you will be lead to believe that the most important thing to consider when purchasing digital cameras is the number of pixels. Although it is important there is much more to deciding on a digital camera than pixels. Pixels are tiny squares, and in new models other shapes, that make up the image. Obviously the more pixels the sharper the image. The more pixels there are the more detailed the image.

Almost all of the digital cameras on the market today produce images with at least 4 million pixels. With this resolution you can print images up to 8×10 which will look very good. Since most people do not print images larger than this a camera with 4 million pixels or more should meet all of your needs.

Try Different Cameras Before you Buy

Different cameras can have very different image qualities even though they may have the same number of pixels. This is due to different types and sizes of sensors on which the images are recorded and the various qualities of lens used. It is recommended that you purchase a memory card and take it in with you to the camera store. Then you can try out various cameras by taking photographs on your memory card. You can then take the pictures home and view them on your computer. Make sure to take notes so that you remember which image was taken on which camera.

Digital cameras are constantly changing and being improved upon. Every few months it seems there is a new model out with more pixels and better features at a more affordable price. Do not let this bother you. Take the time to choose a good digital camera which makes quality photographs and enjoy the benefits of digital photography for years to come.

Digital Camera Care

After spending money on a quality digital camera, it is important to take the time to maintain it properly. Your camera will last much longer if you take preventative measures to keep it in the best condition.

The most important, and delicate, component of your digital camera is the camera lens. This serves as your window to the world, and once scratched it will require professional intervention to fix. For this reason, it is imperative that you protect the lens. First of all, when you are not taking photos your lens cap should always be on to keep the lens clean. Do not touch the lens directly with your finger. The oils left behind by your skin will be difficult to remove, making the view blurry at best. If your lens should get dusty or dirty, use a cleaner and cloth made specifically for cleaning camera lenses.

The body of your camera should also be kept clean and free of debris. Keep the camera in a case or pouch when not in use. If it should get dirty, wipe it down with a soft dry cloth. If you camera has an LCD panel, it is acceptable to breath lightly on it to add slight bit of moisture before wiping it down with a soft cloth.

Digital cameras should be kept dry. Most cameras are not waterproof, and should not be in situations where they could be submerged in liquid or even splashed. If your camera should get wet, it is a good idea to turn it off, remove the battery, and remove the memory card. Leave the camera out to air dry for one to two days. At that time if the camera is not functioning properly you will need to contact a professional repair company or the manufacturer for advice.

In general, your camera will do best if stored in mild, dry conditions. Extreme temperatures can be damaging so try not to leave your camera in your car or any super sunny locations. Another good idea is to save the silica gel packets that come with many purchases to prevent moisture damage, and place them in the container where your camera is stored. If you plan to store your camera for a long period of time without use, you should first remove the battery from the camera. This precaution will prevent damage in case the battery should leak.

Finally, if you are planning to take photos in a location where you believe there will be a higher risk of damage from water or soil or other conditions purchase a disposable camera and leave your digital at home. Better safe than sorry.

Things You Need To Know Before You Buy Digital Camera

Digital cameras come in many sizes, colors, brands, zooms, resolutions, playbacks, etc. There are so many features and qualities that are being placed in the devices that buyers especially first timers become overwhelmed and dizzy with these outstanding arrays of gadgets. This is even without including the various advertisements and different ratings that are used to promote these products.

So what are the things to look for if you want to buy digital camera? To be able to answer these, there are 2 sets of information you have to know before you can decide. The first type of information is defining what YOU need and want in a digital camera. To do this, you can ask yourself the following questions:

– What do you want to take with your digital camera? Before you buy digital camera, it is important to determine what kind of pictures you want to take with it. If you are a digital photography enthusiast, any digital camera will not just do. You have to look for features that can support the zooming you need, the resolution, etc.

– How much is your budget? This is a very important question any person who intends to buy digital camera should ask. Because no matter what your needs and wants are for the device, your financial resource will play a huge part in dictating the type of digital camera you will buy.

– What are you resources? When you buy digital camera, sometimes the spending does not end there. You also have to consider the capacity and the power of the computer and the printer you will be hooking your camera with for your editing and printing needs. Editing software are already included when you buy digital camera but other devices aren’t. Aside from a printer, ink and paper for printing, you might also need additional memory cards for your camera and a more powerful computer to support image editing and image storage and retrieval.

After answering these 3 questions, the second set of information you need to know before you buy digital camera are the features that you need in the device. These are:

– Resolution. Before you buy digital camera, check first its capacity to produce high quality photo images. The number of pixels indicated determines resolution. The more number of pixels, the higher the resolution which can make photos to be enlarged without losing image quality.

– Built-in memory. Digital cameras need memory cards for picture storage. When you buy digital camera, make sure that the gadget that you buy does not only have a “built-in” memory but should also have a card slot for external and additional memory. This allows you to change full memory cards conveniently while shooting your pictures.

– Look and feel. It is essential for you to feel comfortable holding your digital camera while shooting. So, before you buy digital camera, it good to test and check if you are comfortable holding it and using it. Consider where the buttons are located and how they are spaced out and see also if you feel comfortable using the viewfinder.

– Battery life. Digital cameras use up batteries fast and batteries are expensive. Before you buy digital camera, consider if the camera’s batteries are rechargeable. This way you can recharge them. Take also into consideration an AC adapter when you buy digital camera. You can attach this to the camera when you are viewing your pictures or uploading them

– LCD. The LCD is a special consideration you have to look into when you buy a digital camera. This is a small screen located at the back of a digital camera that allows you to preview the pictures you took. This has to be considered when you buy digital camera because it uses up a lot of battery power.

– Special features. Special features that will suit your needs should be thought about, too before you buy digital camera. If you want your camera to have good zooming, you can opt for those with optical zoom lenses. A diopter adjustment on the digital camera’s viewfinder will also be beneficial to those who regularly wear glasses and wish to buy digital camera. Other features such as remote control, tripods, etc. can also be considered when you buy a digital camera.

With these information, you can now figure out what you really need and want before you buy digital camera.

What Are The Different Battery Types Of Digital Camera

One of the most critical accessories of a digital camera is perhaps its batteries. There are some digital cameras where the battery life is so limited that it drains with only a couple of hours’ shooting. Yet there are also digital cameras which are famous for its battery life which simply goes on and on. Thus it is important to know your camera usage methods which can then lean you on to the type of battery you will need for your camera.

There are basically two types of digital camera batteries. One is the standard AA type and the other is rechargeable. The latter is also known as a proprietary battery as it made by the same manufacturer.

A proprietary type of battery is comparatively more expensive, lighter in weight and more tight and compact. The cost makes the purchase of one or two back-ups slightly prohibitory.

The standard alkaline AA size batteries usually have a very short life – at times even less than an hour, when used in a digital camera. These batteries make good back-ups, especially if you are traveling. A better option would be to use the Nickel Metal Hydride (NiMH) batteries for digital cameras, with a charger. This rechargeable option has a longer life and comes at an affordable price.

The other two types of AA size batteries are : the Lithium batteries, which can not be recharged and the rechargeable Nickel Cadmium (NiCD) batteries. The Lithium digital camera batteries last longer than mere alkaline batteries, as well as have a good performance in cold weather. Yet their price and non-chargeability reduce the appeal in comparison to NiMH batteries. It is important to ensure that your digital camera can load a lithium battery. The advantage of a NiCD battery is that it can retain charge when not in use while the disadvantage is that the battery needs to be fully discharged before you can recharge it. This can be very cumbersome and inconvenient.

If you wish to conserve battery life, it is prudent to make judicious use of the LCD screen of your digital camera, this element consumes maximum power when in use.

If you going to stay away from a power source for a long time, it is always wise to take at least one set of back up. The standard alkaline AA size battery is good enough for this purpose, in case your usual digital camera battery packs up.

Digital Camera: The Future Of Cameras

Basically a digital camera is a deice use to capture pictures without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes. It has a built in computer and records the images it captures in an electronic form. Having and operating one does not even require the use of electricity.

Since the images that a digital camera captures is in electronic form, it is a language recognized by computers. This language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just took. Just like any conventional cameras, a digital camera is furnished with a series of lenses that focus the light and creates the image that you want to capture. The difference here is then; a conventional camera focuses its light on a film while a digital camera focuses the light into a semiconductor device that electronically records the light. Remember the built in computer, it comes in here and breaks this information to digital data resulting to all the features of the digital camera.

Another feature of the digital camera is that it has a sensor that converts light into electrical charges. A charge coupled device or CCD is an image sensor that is found in a digital camera. While other low-end digital camera use complementary metal oxide semiconductor or CMOS as an image device, it can still become better and more famous in the future but most engineers are do not believe that it can replace the CCD for higher-end digital cameras.

A collection of tiny diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of the electrons gathering will be larger.

The price of a digital camera nowadays have been depreciating, one of the main reasons of this is because of the introduction of CMOS image sensors, this is because CMOS sensors are less expensive and are easier to manufacture than CCD sensors. A CCD and CMOS sensor works the same way at first, by converting the light electrical charges into photosites. Simply putting it, is to think that a digital camera works in such a way as thinking that the millions of tiny solar cells, each of which forms a part of the whole image. Both CCD and CMOS do this task using different methods.

When shopping for the best digital camera, take note of these key features.

Image quality. Check the resolution of the camera. The higher the resolution, the more thou will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.

Lens. Choose a digital camera with better digital zoom. The digital zoom of the camera will enable you take the pixels from the image sensor and incorporate them to make an image.

Power. Always opt for rechargeable batteries, they can always come in handy, plus you don’t waste as much money on the disposable ones.

Options. So you can choose the one that gives options that best cater to your lifestyle, so you won’t ever whine how you never get the right pictures.

Memory. If you’re a photo freak, be sure that you have enough memory in your camera.

Physical. If you are going to be bringing it everywhere, choose a handy and portable digital camera. This way, it won’t always feel as heavy and bulky as those cameras that you see professional photographers are always dragging on their neck. Don’t they ever get tired of that?!

Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer software is, you don’t want to go running around the whole state or the country looking for a computer that’s compatible with your digital camera, wont you?!

These are just the basic things you have to look for in a digital camera when you buy one. A digital camera is so great that it is quickly replacing all conventional cameras in the market, with all its technology and portability, truly the digital camera is the future of cameras.
