So you have decided to buy a digital camera for someone. Digital cameras are hot gift items. They are also high tech devices with many features and options. This article will try to help you pick up the right digital camera by understanding the considerations when buying one.Current camera: If the gift receiver is already using a digital camera you should get the model number, the memory storage and the accessories they have. In such cases getting a digital camera would only make sense if you can afford to buy a new digital camera that is significantly better than the current one they have. A better camera is not simply one that has more mega pixels. As you will see later other considerations like lenses, flash and battery are no less important.Photography and technology level: If the gift receiver is savvy when it comes to technology and photography you can consider higher end cameras that allow more flexibility and options but are harder to use. Digital SLR cameras fall into that category. If the receive is not into photography or technology you might want to choose a camera that is easier to use such as a digital point a shoot one. It can result in high quality pictures, is easy to use and thus can be very satisfactory to the amateur user.Expected usage: What is the expected usage of the camera? It is hard to answer this question but you can try to estimate based on knowing the gift receiver. For example if he or she travel a lot for long periods you want to pay attention to features such as camera weight, size, battery life and memory storage. If he or she hardly travel these features are less important. Additional cost: The cost of owning a digital camera is not limited to the money paid to purchase the camera. In most cases the owner will spend more money on accessories and other additional products. When giving a gift you want to make sure that the receiver would not have to spend more money in the near future for such additional accessories. To make sure that it does not happen the gift should include additional accessories such as batteries, memory cards, lenses and cables as needed. How many megapixels: It is hard to avoid this question. New cameras are packed with an ever increasing number of mega pixels. Is more mega pixels better? it really depends. More mega pixels is important if the receiver is going to print photos (especially enlargements) or if they are going to zoom in and crop fine details out of big photos. If they just plan to view the photos on their computer screen and maybe print a few 4X6 prints every now and then than 2 or 3 mega pixels is more than enough (yes… just 2 or 3). When buying a gift you would want to buy what is considered the standard megapixels number to date. A good advice is to buy what is considered standard. If after budgeting for extra accessories you still have more money to spend on the gift you can always go for a higher megapixels number.Batteries: There are two kind of batteries that can power a digital camera: disposable or rechargeable. The advantages of disposable batteries are that it is easy to buy a few, carry them and replace the ones that are empty. They are available in any store and thus very convenient when traveling. The disadvantages of disposable batteries are the cost of buying new batteries every time your batteries are empty and the capacity (in most cases disposable batteries do not last as long as good rechargeable batteries). Disposable batteries are not friendly to the environment you do not want to get them for someone who is environmentally conscious. Rechargeable batteries require only one purchase. The disadvantage is that if you run out of batteries during a photo shooting session or somewhere away from home or a power supply you can not just buy another battery. If you know that the gift receiver travels a lot and might be involved in long photo shooting session you might want to include an extra battery in your gift. Zoom: There are two types of zoom optical and digital. Optical zoom works by physically moving the camera’s lenses and changing the focal length. By changing the focal length you can make objects appear bigger and fit the full photo frame. Digital zoom works by applying built-in software in the camera to define a portion of interest in the photo. Once chosen the software crops the rest of the photo and enlarges the area you chose to fit the complete photo frame. The downside of this digital process is that the enlarged photo quality is lower than the original photo’s. The conclusion is that optical zoom is superior to digital zoom. From a practical point of view digital zoom should not be considered zoom at all.
Some manufacturers state the camera’s zoom figure without specifying if it is optical or digital. This information is confusing and done on purpose to inflate their real zoom numbers. When you compare different cameras zoom always compare their optical zoom capabilities. You can totally ignore the digital zoom figures.

Capturing moments was never so easy before digital cameras came into the photography world. Ever since, there has been a big international market dealing with digital cameras. Japan, South Korea and China have been the main players in manufacturing new digital cameras since its inception. Today, no media house can run without digital cameras. Forget media agencies, in our day-to-day life, we have started considering digital camera as a handbag’s must-keep item. It has truly given a new definition to the world of photography.

Many kinds of digital cameras with different features are hovering around the market today. And you need to decide on your choices and pick up the right one that fits your clicking needs. You must have already heard a lot about the top brands such as Kodak, Nikon, Canon, Minolta, Sony, Panasonic, Polaroid, Olympus, Fujifilm, HP, Samsung, etc. This article discusses features of famous brands and models of digital cameras to help you select the right one for yourself.

To start your selection process, you must consider whether you are looking for small and compact pocket camera, an advanced camera, a high zoom capability camera, or an SLR camera. These can range from USD 100 to USD 2,000. You will need to take your pick based on your budget and requirements.

What are the features that you should compare between brands while selecting a digital camera? The most important feature is its resolution in mega pixel. In simple language, this figure tells you how much you can expand your picture without parting with its quality. The higher the resolution, the better. But this doesn’t mean that you have to go for the highest available model in the market. Usually people print photos that are sized 4×6 in or 5×7 in – for this any camera above 4 mega pixels will deliver great results.

Other feature that you should evaluate is zoom-in capability. Optical zoom and digital zoom are different terms. Optical zoom means actual zoom done by the lenses, while digital zoom simply increases the size of the picture display without increasing any details. In simple terms 3x optical zoom means you can get three times closer picture of the image you see with your eyes. For this reason, optical zoom is better.

The third important feature is compatibility with other devices. Find out if the camera you are going to buy is compatible with your computer, printer, memory card, USB drive, etc. Cameras have inbuilt flash memory but the space is limited, so you would have to buy external memory cards, popularly known as Secure Digital Card (SDC) and Multi Media Card (MMC).

The next important feature is the size of the screen that provides digital display of the image instantly. These screens were the major reason that digital cameras replaced conventional cameras so fast. The screen gives you the ability to review the image and delete the ones you do not like. The LCD digital camera screens are up to 3 inches in width.

The other features that make your camera more convenient include automatic light adjustment, automatic flash, red-eye reduction, file format (TIFF, RAW or JPEG), audio and video capability, image stabilizer, manual controls for aperture and exposure, camera speed, weight and size, body type, battery type (lithium of normal), battery life, picture modes for morning light, day light, cloudy day, etc.

The varieties and features of digital cameras are so many that it becomes really difficult for a first-timer to select one. This is worsened by everyday technological advancements. But all the features mentioned above impart a whole new dimension to photography and they make it easier for even an amateur to click great quality pictures.

Capturing beautiful moments and making them accessible quickly is no longer a rich man’s forte. Most of us have access to our memorable moments in just a click away. Digital cameras save you a lot of time. Once the photo has been taken, you can just download those images in a computer and make them accessible on the net in various ways. Digital cameras record and store photographic images in digital format. Capturing pictures is usually accomplished by use of a photo sensor, using a charged couple device (CCD.) After transferring the pictures to your computer, you can edit and save them in a compact disc or hard drive.

With digital cameras you can instantly seize the picture you would love to keep forever. Delete unwanted pictures easily. No hassle of buying films. You don’t have to print every picture; you have complete control of the final print after editing on computer. No worries of negatives getting spoiled or lost. You can store many images without having to change or buy films.

There are many brands of digital cameras available in the market today. These include: Sony, Canon, Olympus, Nikon, Kodak, Minolta and Fuji. These are a few famous brands worldwide. Even basic digital camera models have plenty of features, levels and menus. This makes it difficult for beginners to select the right camera meeting their needs. Digital cameras are available in all price ranges depending on the amount of features they have. Before you start comparing the features you should decide for what purpose you would like to use your digital camera. The best way to start your search is to log on to the net and visit all the sites that offer feature and price comparisons for different types and brands of digital cameras.

Almost all digital cameras today have live-preview functionality, where a screen is provided in the camera to see the preview of the image that you just clicked. The most commonly compared feature in digital cameras is the “mega pixel.” This means the amount of pixels in millions. Therefore, a four mega pixel camera would have four million pixels. The other important features to compare include optical and digital zoom capacity; connectivity with other devices such as computer, printer, etc.; the internal storage space as well as compatibility with external storage devices; memory cards; batteries; and image file formats.

Many digital cameras offer connectivity through USB port, FireWire port, USB PTP mode, Bluetooth, Wi-Fi, etc. These days, many cameras are offering PictBridge mode that allows direct printing from the digital camera without the mediation of a computer. Though all cameras have some amount of internal memory, external memory cards are required to save more pictures. These include Micro Drives or Compact Flash memory cards that are generally used for high-end professional cameras. Memory Stick by Sony is a proprietary flash memory card. SD/MMC, Mini SD and Micro SD cards are the ones used mostly for commercial digital cameras.

If you are an amateur photographer, then you should select a camera with automatic settings and features. This will help you in getting the right pictures based on the amount of light and scenes without too much effort. But if you are looking for a professional camera then you should pick the one that allows you to select all shooting modes manually. There are many shooting modes available in the latest models of digital cameras including landscape, portrait, panorama, action settings, night mode, beach mode, snow mode, and sunset/sunrise modes.

The common formats in which you can take out the image output include JPEG, TIFF, DNG, etc. For videos, the most common formats are AVI, DV, MPEG, MOV, WMV, ASF, and MP4.

Electronics greatest technological breakthrough in this modern age is the digitization of analog signals. Digital information, which is represented by 1s and 0s, is formed upon successful conversion of analog information, which is represented by a fluctuating wave. This conversion of analog to digital has made the world of science and technology make great advances into the field of computers, Internet, satellites, and space research.
On the consumer domain, the benefits of this technological breakthrough can be witnessed in consumer electronic products like TVs, computers, cameras, camcorders, CDs, DVDs, etc. Digitization gave rise to microchips, which could be programmed to perform any task. With the utilization of the microchip, the digital camera was born.
In a digital camera, the lens focuses the image, the shutter allows the entry of light reflecting from that image into the camera, for a fraction of a second, and the aperture determines the quantity of light allowed inside the camera. When the light enters the camera, it does not fall on a photographic film as it does in a conventional camera, rather it falls on an image sensor.
The image sensor is an electronic device, a semiconductor, made up of photosites that measures the light intensity. The photosite can only measure the intensity of light and cannot recognize any color. To overcome this, each photosite is covered with a color filter of red, or a green, or a blue color according to a pattern known as the Bayer pattern. Since the human eye is twice sensitive to the green color, the number of photosites having green color is twice the number of photosites having red or blue color. Millions of photosites are covered by this Bayer pattern. Each color occupies a single photosite, which is known as a pixel.
The more the number of pixels, the greater is the amount of detail that can be captured. The detail of the image is called as resolution, which is determined by the quality of the lens and the number of pixels in the image sensor. High-end digital cameras have about 12 million pixels, whereas professional digital cameras have about 20 million pixels.
The information of the pixels is recorded as electrical analog signals, is amplified, and then is fed into a converter, which converts the amplified analog signals into digital binary numbers, with respect to the color information of each pixel. These digital binary numbers are then fed into a computer chip residing inside the camera. The computer chip analyzes the digital binary numbers that have been made as per the color of individual pixels. This information is known as RAW data. For analysis, the computer chip subjects this RAW data using a technique known as demosaicing.
In this technique (demosaicing), the pixel color is determined as per the color of the neighboring pixels. For example, if a red color pixel is surrounded by blue and green pixels, then that red color pixel is treated as white color, since the color white is a combination of the colors, red, blue, and green. After demosaicing is complete, the image is further subjected to the photographer`s settings of the camera, like adjustments made for brightness, color saturation, contrast, etc.
High-end digital cameras usually do not do anything more to the image thus produced. However, professional digital cameras have a sharpening algorithm, which heighten the sharpness and clarity of the demosaiced and settings adjusted image. Professional digital cameras also have the option of saving the image in its RAW data before any demosaicing or adjustments are made by the computer chip. This is to give control to the professional photographers to make changes to the RAW data as per their own choices.
The image can be saved in an uncompressed format like TIFF or a compressed format like JPEG. Uncompressed formats preserve greater information; thus, the detail of the photograph is much more than a compressed format, where detail is less, as lesser information is stored. Hence, compressed formats are also known as lossy formats, since details are lost. An uncompressed format increases the file size, whereas a compressed format reduces the file size. Depending upon the need, the image can be saved either in an uncompressed or a compressed image format, as bits and bytes in a memory card. The stored image can be viewed on the digital camera`s display screen as a digital photo.
This digital photo can then be transferred from the digital camera to the computer`s hard disk via the serial port or USB port or FireWire port or Bluetooth wireless using Wi-Fi connectivity. RAW data and uncompressed data like TIFF take a longer time to transfer than compressed data like JPEG or GIF.
Once the data has been transferred to the computer`s hard disk, any photo editing software can manipulate and adjust it, as per the individual tastes and requirements of the photographer. The digital photo can then be printed on photographic paper, specially coated paper, or any other paper via a color inkjet or laser printer. Utilizing a plotter, it can be printed in larger sizes, in any other medium like canvas, acrylic, vinyl, etc. The digital photo can be saved on a hard disk, pen drive or a CD, for archival purposes.
With passing time, more and more features are being introduced in a digital camera. Nowadays, audio-video recording is also fused with the still image capturing capability of the digital camera, making them small camcorders (camera + recorders).

Digital cameras can be a lot of fun, especially if you’re really into photography. A digital camera opens up a whole new world of possibility with more capabilities and higher picture quality than standard cameras .
With new computer technology adding to the experience of digital cameras, technology lovers around the world will be able to get more out of their cameras and the software that goes with it.
Of course, it can be difficult sorting through all of the information about digital cameras. Finding what you’re specifically looking for can become complicated in the web of camera information, ratings and reviews contained on several technology-oriented websites.
If ratings and reviews are what you’re looking for, however, look no further than the Digital Camera Review website. At www.dpreview.com, you can find a wealth of information about digital cameras that will really help you decide what you need.
It may seem like an elementary statement, but when the time finally does come for you to buy a digital camera, the decision is entirely yours. All of the ratings and reviews can only get you so far.
You must ultimately make a decision based on how you think you will use your digital camera, what your budget is, and which accessories you hope to be able to use.
There are a number of trusted names in digital cameras that have wide varieties of camera types. Pentax digital cameras, for example, are among the more trusted names in cameras. The Pentax digital camera is known for being reliable and easy-to-use, plus the price is usually very affordable.
The Nikon D70 digital SLR is also a popular choice among digital camera enthusiasts. The price on this 2004-released camera is right, and it offers a high degree of functionality without requiring too much of the user.
The technology behind the camera is basic, allowing for ease of use without running to the instruction manual for each snap of a photo. The Nikon D70 digital SLR is also one of the top-selling cameras in the world.
It is important to realize that these cameras are just a few of the many options that are available to someone who is seriously in the market for a digital camera. While these are some of the more popular models, there are a number of manufacturers who make high-quality cameras on a much smaller scale.
Take the time to visit your local retailer and take a look at what every manufacturer has to offer. Somewhere in the mountain of options is the perfect digital camera for you.

Canon is well known across the country as an imaging equipment and information systems. Their many products include copiers, printers, lenses, camcorders, semiconductors among others, and of course Canon digital cameras.

The latest high end canon digital camera is the PowerShot S2 IS. This is a 5.0 mega pixel Canon digital camera that features a 12x optical zoom and a 4x digital zoom. This baby is furnished with Optical Image Stabilizer (that is what the IS in S2 IS stands for) that eliminates camera shakes for people who have shaky hands or for taking camera shots. The UD lens found in this canon digital camera provide amazing color accuracy throughout the whole zoom area.

These are just some of the many features of the SD500. There are more to the SD500 that has yet to be discussed. Check canon’s website at www.usa.canon.com for a full profile of the SD500 and to other latest releases and products.

It helps when learning to use your new digital camera to also know what some of the more common terms mean. Below you will find many of these common terms defined..

Automatic Mode — A setting that sets the focus, exposure and white-balance automatically.

Burst Mode or Continuous Capture Mode — a series of pictures taken one after another at quickly timed intervals with one press of the shutter button.

Compression — The process of compacting digital data, images and text by deleting selected information.

Digital Zoom — Cropping and magnifying the center part of an image.

JPEG — The predominant format used for image compression in digital cameras

Lag Time — The pause between the time the shutter button is pressed and when the camera actually captures the image

LCD — (Liquid-Crystal Display) is a small screen on a digital camera for viewing images.

Lens — A circular and transparent glass or plastic piece that has the function of collecting light and focusing it on the sensor to capture the image.

Megabyte — (MB) Measures 1024 Kilobytes, and refers to the amount of information in a file, or how much information can

be contained on a Memory Card, Hard Drive or Disk.

Pixels — Tiny units of color that make up digital pictures. Pixels also measure digital resolution. One million pixels

adds up to one mega-pixel.

RGB — Refers to Red, Green, Blue colors used on computers to create all other colors.

Resolution — Camera resolution describes the number of pixels used to create the image, which determines the amount of

detail a camera can capture. The more pixels a camera has, the more detail it can register and the larger the picture can be

printed.

Storage Card — The removable storage device which holds images taken with the camera, comparable to film, but much smaller. Also called a digital camera memory card…

Viewfinder — The optical “window” to look through to compose the scene.

White Balance — White balancing adjusts the camera to compensate for the type of light (daylight, fluorescent, incandescent, etc.,) or lighting conditions in the scene so it will look normal to the human eye.

Digital cameras are no longer a luxury these days, with high resolution mega pixels and sophisticated features coming within a very appealing price range. And thanks to many comprehensive digital camera reviews, it’s easy to pick the most sought after features and qualities and still stay within a budget.
Most people turn to digital photography because they like the ease of printing and sharing the photos on the web. Business owners choose the digital quality for their product catalogues or brochures, students employ digital cameras for their projects and with digital cameras in most recent cell phones, even a child can take a snap and publish it instantly on the web. And thanks to the newest lens and zooming qualities, you don’t have to be a seasoned pro to shoot close-to-professional images with modern digital cameras.
You can hardly find a digital camera today with resolution lower than 2 megapixels – two million color dots per picture. This is a decent quality for most uses, including printing the photos for the home or school use. The higher the megapixel rate, the bigger photos you can print without sacrificing the quality. However, if you are not a professional photographer or a graphic professional who deals with upscale images all the time, you don’t really need a digital camera that produces more than 8-megapixel camera – and these rarely become available for less than $1000. Plus, if you seek to print large detailed photos, make sure you have a high-quality printer that can reproduces all the tiny details that make a difference.
When you pick a digital camera, you should also pay attention to the zoom number. Digital cameras have two different kinds of zoom. Digital zoom enlarges all pixels digitally, while optical zoom enlarges the image with the lens magnification. Since you can always enlarge the image later, on the computer using the Photoshop or other image manipulation program, you would be better to concentrate on higher optical zoom rate. The average optical zoom for midlevel digital cameras is 2 to 4x.
There are a few other options to consider: whether a digital camera uses a rechargeable batteries (zoom and LCD screen consume a lot of energy); whether the digital camera has a standard flash memory (you may need to buy a few more flash memory cards in future), and if the menus are easy to understand. If you travel a lot, you may want a digital camera that is lightweight and compact.
Even if you decide to pick the least expensive digital camera to serve your basic photography needs, you will still enjoy all the benefits of digital photography: no film rolls to buy, no wasted photos to dispose of and best of all, no waiting time to get them printed. New models of digital cameras are constantly launched, and the older ones are becoming less expensive day by day. Know your priorities, check the most recent digital camera reviews, and there should be a digital camera to perfectly suit your needs.

Digital cameras are available in many shapes and sizes, represent various specifications, and offer an impressive array of features in many price ranges. This is why their popularity is soaring all over the world, with many people already using one for their own pictures. They have become an integral part of many geographic and corporate cultures.
Digital cameras have become more than simply replacements for 35-mm cameras, however. They can be used for taking videos as well as still photos by upgrading the camera’s memory card to increase storage capacity, allowing them to replace the old VHS recorder as well.
While enjoying significant popularity on their own, digital cameras have also become integrated within a large number of other hand-held tools, such as PDAs and cell phones. Technology now allows these devices to incorporate a digital camera within them, making the use of both devices much more functional and convenient.
Many brands of digital cameras are available today with a wide range of features. All the big camera names of the past, Kodak, Nikon, Canon, etc., offer everything from 35-mm to digital products. Even companies better known for the computer products, such as Panasonic, Sony, and HP, are now offering digital cameras in their product lines.
Digital Camera Considerations
Digital cameras differ from conventional cameras by having a small LCD screen, sometimes including a viewfinder. This screen is similar to a TV screen, allowing the user to better see the picture before snapping it. Some have screens large enough to include much more of the subject and background than has ever been possible before.
Instead of film, these devices have slots to hold a memory card or “stick.” The amount of memory available within any device can be measured along a range of megabytes to gigabytes, depending on how much you’re willing to spend. Getting a camera with more memory means spending more money, but the extra storage capacity can be worth it.
Another feature to consider before purchasing is the type of battery used. While some units feature disposable batteries, the more expensive cameras use rechargeable batteries for longer energy life. Disposable batteries typically wear out quickly, while a charger is generally bundled with those cameras using rechargeable batteries.
Another consideration when considering which model to purchase is how the pictures are downloaded. Most digital cameras have a USB port to allow easy connectivity to a computer, but some require removal of the memory card and using a reader to download pictures into a computer.
Digital Camera Features
Those considering purchasing their first digital camera should at least know the basic features of an individual camera before spending a lot of money. While snapping a picture is basically the same in all cameras, there are many other features that will influence your decision. The number of megapixels used when taking a picture should be among the top concerns. Megapixels represent the number of pixels, or dots, that make up the picture. The more pixels used in a photo, the greater the clarity will be. Cameras that utilize a greater number of pixels are capable of producing better resolution over a larger image, but these pictures require much more memory space for storage.
Another important feature to consider in a digital camera is the zoom feature. The terms to be familiar with are optical zoom, which utilizes a moving lens and brings the image forward to make it appear closer, and digital zoom, which is used to crop and stretch the image. Most digital cameras have two-zoom capability.
The last feature this article will discuss is the durability of the camera’s case. Many buyers don’t consider this as important, but camera cases made mostly of plastic are relatively fragile. Some camera cases are made from a combination of metal alloy and plastic that is more durable and can sustain more jarring without allowing internal damage, although neither option can guarantee your camera’s safety. It’s better to spend a little more for a case that will better protect your investment.

We have entered the age of digital cameras. The advantages of the traditional film camera over the digital camera have disappeared, and the former are increasingly becoming a part of our normal lives.

A digital camera produces digital pictures – these are so easy to load on a computer and they can be emailed across the world to your friends or relatives in a matter of minutes. It is easy to check digital pictures and delete them if you wish. If you find that a picture you have taken is useless, you can delete it easily instead of wasting film, which you cannot reuse. A film can go bad over time; so keeping a digital camera handy for use whenever necessary is a fine option.

One can characterize digital cameras by the image size. Digital pictures are made up of color dots called pixels. The pixels are expressed by height and width, for example 320 x 480. These numbers are then multiplied, providing the total amount of pixels. Large number of pixels provides more detailed images, but this resource is available mostly on the more expensive cameras. Two megapixels, which means 2 million pixels, is at the low end, and may result in defects when the picture is enlarged. On the other hand, seven megapixels represent a robust picture and can handle enlargement well.

One other point to consider is zooming. The Optical zoom feature adjusts the light which enters the camera, and this makes the scene to appear closer. The digital zoom feature adjusts the picture after being digitized, to produce a closer appearance. Both can produce the desired result, but optical zoom is preferable.

Digital cameras also come with internal storage, but this is usually too small. So you have to look at the kind of add on storage that the camera allows. The additional storage usually comes in the shape of a thumbnail sized chip, and you can carry these around conveniently if needed.

The battery is another area you have to consider. Some digital cameras use standard sized batteries, while others use less common, proprietary sizes. Some batteries hold a charge better; some battery systems are rechargeable, while some cameras just hog power.

Then there is the preview screen – which is an LCD (liquid crystal display) screen, which shows you what the camera would see at any given point if you wish to take a picture. In this system, the screen is active whenever you are preparing to take a picture, but this will also consume the battery while you are doing it.

But you also have digital cameras that come with an optical viewfinder that does not consume power. This is helpful when you are waiting for the right moment to shoot, or when you require the preview screen to compose a picture at a difficult angle. You can also preview the saved picture on the screen and delete the ones you don`t want to keep, and thus clear storage space.

With the ever changing and advancements in the technology these cameras also keep getting better and better. The basic features are common for all types of digital cameras, only the add on features keep varying with the price and the manufacturers choices. Usually they allow you to take pictures automatically, i.e. you can take your own picture, adjust the picture that you have taken may also adjust the settings according to the color choice, brightness, etc. You may also create your own video album!!

Thus it is apparent that the digital camera rules over the traditional cameras. There can`t be any competition between the two because without doubt digital cameras dominate the scene. They have effectively changed the way the world takes pictures and possessing a digital camera is a dream for many budding photographers.
