Digital Camera has become a very popular consumer item, since it makes so easy and cheap to take pictures. However, some buyers are impulsive by nature and they are hardly aware of the standard features of digital cameras. Only after using the camera, they may realize its drawbacks. Therefore, it is important to know some standard features of digital cameras so that one can make the right decisions while buying this gadget.
The following are some standard features:
Computing Platform: Most digital cameras have interface compatibility with Mac as well as Windows operating system platforms. However, some cameras might have more software for one platform than the other, where as a few will work only on one platform. In this case, usually these cameras work on Windows platform.
Image Quality: It basically includes factors such as exposure accuracy, color purity, optics (lens) quality and image compression techniques.
Onboard Image Capacity: Whether a specific amount of onboard image capacity is sufficient or not depends largely on your application. Image capacity and image quality share a strong co-relation with each other. For instance, there is not point in having a digital camera that offers high image capacity whereas the amount of storage is not adequate in relation to the resolution. Beware of the cameras that promise a large number of images but lack actual storage space. It might affect the image quality of your photos. Standard onboard camera memory might range from 2 to 16 MB and the image storage capacity can vary from 10 to 100+ images, depending on the image resolution.
Reusable Memory Cards: There are quite a few digital cameras that allow storing images on plug-in cards and this enables users to add as much or as little memory to the camera as per individual requirement. Unlike the older version of memory card where a single type of memory card known as Liner PCMCIA was being extensively used, now memory cards can be found in different types. Some of the most popular cards are Compact Flash and FlashMedia.
Exposure Versatility: Digital cameras are unable to handle different lighting conditions. This drawback is not found in film cameras as we can compensate for different lighting situations by using different types of films. So, since the image sensor of a digital camera acts as a film, users find nearly impossible to change this setup. However, you can ensure that the digital camera you are buying has the ideal camera exposure system, such as shutter speed, variable lens opening and supplementary flash to handle a wide range of shooting conditions.
Other features:
Consider buying a waterproof camera as it can withstand moistures.
The camera you are buying should preferably have ISO support for crisper and cleaner images.
Go for higher mega pixel resolution cameras, which will offer you greater cropping ability. The higher the mega pixel resolution, the more one can enlarge his photographs. But don`t get too fussy about mega pixel resolution as it is not everything in a digital camera.
Look for pre-programmed scene modes in your camera which will take photos even in the tough and challenging lighting conditions.
While buying, focus more on optical zoom of a digital camera and not so much on the digital zoom. Optical zoom makes use of lens to get closer shots and delivers better images.
Finally, you have to be careful of not being lured into buying a camera with a `package deal` offer. What costs cheaper could also be cheaper in quality too! Digital cameras have made it easy for those who want to capture special moments. Now with so many features and affordable prices, digital camera have really become a world wide consumer product.

Compact Digital Cameras: Photography?s Mighty Mites
Size may matter, and a lot, to some people, when it comes to some things. But when it comes to cameras, the ongoing advances in digital technology have made compact digital cameras a photography force to be reckoned with.
Compact digital cameras can be safely transported into places and situations in which a larger camera would just be an awkward nuisance, and have to be lugged around in your backpack which is already overloaded and chafing you through your T-shirt. A palm-sized compact digital camera can go unobtrusively wherever you choose to take it, and be ready for action when you are.
What compact digital cameras achieve in convenience of dimension, however, they must compensate for in other areas. You?ll have to adjust to their smaller controls, and some earlier models of compact digital cameras may take longer than you like to ready their flashes, open their lenses, and be up and running. Some of them may take as long as five seconds, in fact, to be fully operational. Five seconds in the world of photography, as you are no doubt well aware, can mean the difference between winning and losing a Pulitzer Prize. For more info see http://www.topdigitalcamerareviews.com on Digital Cameras
Things in compact digital camera land, however, are slowly but surely improving. Compact digital cameras are now available with fast activation, and self-adjusting zoom lenses which will let you capture even rapid motion shots. If the
compact digital cameras you are looking at does not have speed settings, it will be useless in environments with changing light, and useless to you as well. Put it back and continue your search.
Compact Digital camera batteries
Before you decide to go the compact digital camera rout, you will also benefit from an education in their battery capacity. Every digital camera will drain its batteries; some will do it more quickly than others. For more info see

Digital Camera: Top ten buying tips
Zeroing in on the digital camera best suited to your needs can be difficult, especially with the complex array of features and functions available. Not to worry. These 10 buying tips will help you find a camera that fits your needs, budget, and shooting style.
Top Ten Buying Tips
* Select a digital camera with a maximum resolution that meets your largest output you're likely to want. If you want to make 8-by-10 prints, we recommend a 4-megapixel model, though a 3MP camera will do the job. A good 8-megapixel camera can take you all the way up to 16-by-20 prints. If all you want is to take pictures for e-mail or the Web, even 2MP camera will suffice. And remember, megapixels correspond only to image size, not quality.
* Make sure the camera has the right features for your needs, such as video recording, an optical zoom lens—perhaps even manual controls and a histogram. If you wear eyeglasses but like to take pictures without them, make sure that your camera has a focusable diopter, which lets you adjust the focus of the viewfinder so you can see your subject clearly.
* Choose a model with a bright LCD so you can see it when shooting outdoors. And make sure the screen is large enough so you can easily compose and review your images on the camera.
* When comparing costs, don't forget to calculate the extras that may or may not be included, such as rechargeable batteries and a charger, , and a memory card with a high enough capacity to hold all your pictures until you can download them to a PC.
* Nearly all digital cameras have a USB interface. For higher-megapixel models, try to find one that supports USB 2.0 so you can transfer large image files quickly.
* When looking at digital cameras with a zoom lens, what counts is the optical zoom—not the digital zoom. Digital zoom is actually a software function that involves cropping and magnifying an image, resulting in a loss of image quality.
* If you don't know an f-stop from a white balance, a digital camera that has lots of modes and manual settings will generally be overkill for your needs, as well as being higher in price and more difficult to use.
* Look for a digital camera that comes with a pocket-size instruction manual instead of one on a CD-ROM. It's easier to consult when you're out shooting.
* For small, young, or arthritic hands, look for a digital camera with a limited number of buttons, and make sure they're large and easy to access and press.
* Test how fast the camera performs. You will probably be unhappy with any digital camera that takes longer than 4 seconds to boot up or longer than 6 seconds between shots.

* If you don't like the shot you just took, you can instantly erase it and shoot it again.
* Some digital cameras allow you to shoot videos or record and play MP3 sound clips, and some double as a Web camera.
Digital Camera Cons
* Digital cameras cost a lot more than comparable film cameras.
* Generally, image quality may not be as good and the size of the enlargements may be limited because of the digital camera's resolution.
* There's always a time delay from when you turn the camera on until it's ready, as well as from the instant you press the shutter and the picture is actually captured.
* Digital cameras eat batteries, so you'll always be buying or recharging them.
* It's difficult to see anything in the LCD viewfinder in bright sunlight.

Essential Buying guide of your Digital Cameras
Shopping for a digital camera is stressful. Most stores carry a fraction of the 200-plus cameras on the market, and except at specialty stores, salespeople aren't much help. You can ask friends for recommendations, but even if they love their camera, it might be discontinued, given short product cycles. Don't throw up your hands and give up. A little information, some strategizing, and our reviews can make the process less traumatic.
Like PCs, cell phones, and cars, digital cameras come in many sizes, shapes, and configurations. And your buying decision is likewise one you'll have to live with for a while. So break the decision down into a series of factors, then compare cameras based on how well they meet your needs, factor by factor. To determine which camera is best for you, consider image quality, performance, ergonomics, and style, your level (current or hoped for) of photographic skills, and price.
The bottom line is money. When shopping for any luxury item, the best strategy is first to decide what you can pay. Decide on form factor, features, and the rest based on what you're actually likely to use. Then look for a camera that meets your budget.
Digital Camera Choices
Compact cameras aren't the best, fastest, most stylish, smallest, or most flexible digital cameras. They take reasonable pictures and have reasonable feature sets. They generally also offer better performance, LCDs, and optics than the sexier, pricier ultracompacts.
Compacts lack the pro features and performance characteristics of higher-end cameras but fit into handbags or roomy pockets. This is by far the most popular camera category—particularly among bargain-conscious shooters and women—and it represents the best value for the average user. Unless you need a higher-end or smaller camera, this is the type of camera you should consider first. Typical compacts offer great value for money. But not all compacts offer sensibility over luxury.
Ultracompacts are small enough to fit in your palm and stylish enough for any social milieu: They'll fit into tiny bags or suit jacket pockets without ruining their lines. They can be simple—or sophisticated high-megapixel powerhouses. Either way, performance, features, and image quality generally take a back seat to form factor and style. Ultracompacts are for those who want the coolest toys and a camera always on hand.
Enthusiast cameras are full-size models built on bigger budgets than compacts. They offer more precise controls, better lenses, and more features. Most important, they provide superior images, suitable for larger prints. They tend to have lenses that can zoom in closer, faster performance, histograms, exposure bracketing, high resolution, and manual controls for shutter speed, f-stop, and white balance. They're for users who don't want to spend the money on a D-SLR but still want versatility, quick and sure handling, and fast shooting.
Superzooms, which have 10X or greater optical zoom lenses, are a subset of enthusiast cameras. Their large lenses put them into the full-size category, but their prices tend to fall between those of compact and enthusiast models. While some superzooms have high-end features, their users often prefer automatic settings. Some correct for camera shake—which is greater the more you zoom in—via image stabilization.
D-SLRs are at the pinnacle of digital cameras, with true reflex through-the-lens viewfinders, interchangeable lenses, total control over exposure and color, and a host of accessories. Besides pro features and functions, D-SLRs yield performance similar to those of 35-mm film cameras. Most important, they also produce the best image quality of any type of digital camera. D-SLRs usually have fully automatic settings, but to get your money's worth, you'll have to be the kind of shutterbug who likes manual controls. D-SLR users include avid amateurs, pros, and those who need top-of-the-line equipment, regardless of cost.
Digital Camera Features
Megapixels make great sound bites, but optics and processing algorithms are also important. Indeed, just a few sensor manufacturers supply camera makers, so two cameras with the same MP rating may have the same sensor. And we've seen cameras produce better pictures than cameras in the same class with a higher MP count.
MP ratings are useful for determining how large you can print images—as well as how much you can crop images and still retain acceptable image quality. See "Get to Know Your Camera and "More Than Just Megapixels" for more on megapixels.
Image quality is a more useful measure. Most digital cameras produce good images, with color fidelity, sharpness, and dynamic range that will satisfy most users. We rate image capabilities by sharpness (the more lines of resolution a camera can distinguish, the better) and the percentage of transition pixels on a subject's edges (the fewer, the better). We also consider color reproduction and exposure accuracy. For more on image quality and how we measure it, see our explanation in "Superzooms".
If you plan to e-mail your pictures or print them on your ink jet using low-grade paper, you needn't be picky. Other criteria, such as price and size, may be more important. If you want razor-sharp, professionally finished 8-by-10 prints with colors that pop, then image quality is key.
To get top image quality, select from among cameras that we rate at 4 or 5 stars. We won't give a camera these scores if its pictures aren't good, no matter how cool it looks or what bells and whistles it has.
Digital cameras are getting faster, but they're still slower than film cameras. We test each camera's boot time (how quickly it can start up and be ready to shoot) and recycle time (how long it takes to shoot, process, and be ready for another shot). Long boot times are annoying, long recycle times more so. Make sure you can live with a camera's speeds. Try it out, or, if you can't, use a stopwatch to see what a 5-second recycle time really means.
Is the feature set right? Taking digital photos can be as simple as pointing the camera and pressing the shutter button. But digital cameras can also provide as much control over exposure, color, dynamic range, and so on as you want. Also consider extras like in-camera red-eye removal and panorama modes. In general, however, we'd pick a camera that takes better pictures over one with many features. You can always remove red-eye later, but you can't add in detail that a poor camera missed.
Ergonomics and style matter, too. When you try on shoes, you consider what they look like and how they feel. Apply similar criteria to each camera: How does it feel to hold? Is it too large or too heavy? Does a plastic body feel too flimsy? Are the controls sensibly placed? Are there too many or too few? Are the menus easy to navigate? The best menus explain features and settings and even give shooting advice. And don't forget vanity: Does the camera suit your style, or will it embarrass you?

In general, however, we'd pick a camera that takes better pictures over one with many features. You can always remove red-eye later, but you can't add in detail that a poor camera missed.
Ergonomics and style matter, too. When you try on shoes, you consider what they look like and how they feel. Apply similar criteria to each camera: How does it feel to hold? Is it too large or too heavy? Does a plastic body feel too flimsy? Are the controls sensibly placed? Are there too many or too few? Are the menus easy to navigate? The best menus explain features and settings and even give shooting advice. And don't forget vanity: Does the camera suit your style, or will it embarrass you?

Digital Camera Features: What you need to know
Having a digital camera to capture, create and share memories is fun but you must learn how to do it right. Digital cameras that are designed to capture your lifestyle. Here are some of the tips about the amazing ways to help you do it.
Now you must know what digital cameras have to offer. Check out the digital camera features. In order to acquire or shoot great pictures, learn and discover amazing ways about digital photography and what features are most important to help you make the right digital camera purchase.
1. More megapixels, more cropping flexibility
Digital photography makes it easy to enlarge a portion of an original image, a feature known as cropping.
2. Got enough memory for your digital camera?
High-megapixel cameras take great photos, but they also eat lots of memory. View the 'Got enough memory?' demo to find out the ideal memory card for you based on your camera's megapixel size. Buy a memory card for everyone who will use the camera. This reduces the chance of accidentally deleting someone else's photos, running out of memory space or a misplacing a card.
Consider getting a high-speed memory card. They let you take pictures faster — with less time in between shots — and offer faster downloading of images from camera to PC.
3. Optical vs. digital zoom
Optical zoom magnifies like a telescope, with no image quality tradeoffs. Digital zoom simply enlarges pixels already present, causing a rapid decline in image quality.
4. Capturing video and sound
Many digital cameras now let you grab a minute or so of low-quality video. Some even record the audio to go with it.
5. Flashes
Lighting is key for great photos. Many of the built-in flashes on digital cameras are not powerful enough to shoot large groups and may cause your images to have red-eye. Many cameras have a red-eye reduction feature that flashes before the image is taken, to close down the pupil. A better way to eliminate red-eye is to use an accessory flash that attaches to the camera's flash shoe, a feature on advanced point-and-shoot and SLR-type digital cameras.
Some cameras have a red-eye reduction feature built into the camera itself. But all red-eye images can be corrected by using your computer and red-eye reduction software.
6. Image stabilization
Image stabilization, also known as "anti shake," is a digital camera feature that helps prevent blurred images. It reduces the vibration caused by camera shake, slow shutter speeds or the use of a long telephoto lens, when a tripod is not used. Handheld shots can be taken almost two stops slower with image stabilization, helpful when using long telephoto optical lenses or shooting subjects in low light.
7. LCD
The LCD on the back of a digital camera is your screen guide to taking digital photos. It frames shots like a viewfinder, allows you to review recorded images after they are taken and displays the camera's menus and settings. Some LCD monitors swivel and tilt in various directions making it easier to view when held overhead or down low. Today's LCDs are as large as 3" and improving so they can be seen more clearly under a variety of lighting conditions. Some ultracompact digital cameras have no optical viewfinder, only an LCD.
8. Digital camera accessories
You have the digital camera but now you need the extras. Pick up a bag to protect your camera, extra batteries so you're never out of juice, and memory cards for extra image storage. Check out the most commonly used accessories for digital cameras below:
* Camera/Camcorder Bags

11. Transferring images to PC
Connecting your camera is a snap — and once you've downloaded your pictures, you can erase them from the camera's memory and start taking more.
The camera-to-PC connection is typically made in any of three ways:
* USB cable (provided with camera)
