The pixels, optical, memory, camera size, digital zoom and cost of various digital cameras should be compared well before picking any camera. The important task is to put through a sieve all the hype and get the best digital camera suiting your needs.

But before you start comparing the features of different cameras, it is important for you to make certain basic decisions. They are related to identifying your basic needs and prerequisites for the camera. Decide on why you need a digital camera. The purpose should be well-defined. Ask yourself, is it for taking candid snapshots or for serious photography. If you are buying the camera for clicking pictures for an exhibition or a photo website, the criterion of purchase will definitely change. There are different sizes of models that include compact, miniature and big size cameras. Be clear about the size you need to buy.

Then you may start comparing the specific features of the digital camera. You can compare the quantity and quality of the pixel. The more the pixels in the camera, the clearer and quality pictures it would produce. The pixels are nothing but tiny squares of color and light. Thus to get the best camera, you should have the best pixel quality. The sensor of the camera can be called as its eye. Generally, the digital cameras with larger sensors have better quality diodes, which result in sharp and clear pictures.

You should also compare the digital camera on the grounds of its memory. All the digital photographs require the storage capacity of several megabytes. You should compare the capacity of built-in memory of the digital camera. You should certainly go for the one with more battery capacity. A general guidance principle is to have a battery with at least 256 to 512MB of memory. It is important to check the memory compatibility while comparing the digital cameras.

You can also compare the SLR digital camera with compact digital camera. There are many features that you may find in a compact digital camera but not in the SLR digital camera. It can also be vice versa.

The SLR cameras are big cameras, efficient in producing clear, sharp and quite colourful images. While the compact cameras are very small in size and can be slipped in to your jeans pocket quite comfortably. They may not compete well with the SLR digital cameras when you compare their features. But, their size is the feature, which is the major attraction for purchase to many users. When you would compare the working and results of both of these cameras, you can decide as to which one suits the best to your needs.

There are more features that should be compared before buying a digital camera. Optical zoom is much better than digital zoom. Compare the speed of the shutter, time taken to start up, the level of manual override and how instant is the auto focus of the camera.

Keep these things in your mind before the purchase. I am quite sure that you will make the best-for-you pick, prior comparing various digital options. Happy Shopping, for happy digital Clicking!

Shopping for Digital Cameras and Digital Camera Savings

Posted on December 5th, 2009

Purchasing a digital camera can be quiet an arduous task. Making choice between so many digital cameras in the market is a cumbersome process. The digital cameras today are procurable in a variety of models. A number of leading companies are bringing out several new models of digital cameras each year in the market. Amidst this cut throat competition, the customer stays in an illusion by knowing just the superficial details of these digital camera options.

Remember, the companies tell you only about those features of their products, they want you to know about. A layman is not technically adept to go into the details of the digital cameras. A flashy marketing campaign is enough to allure the customers and sell the products. But you can easily get the best with in your budget by just knowing a few basic essentials for shopping a digital camera. This basic knowledge enables you to purchase the right camera, according to your choice.

The first thing to look out while shopping around for a digital camera is the number of mega pixels. You must have come across the advertisements boasting well on the more mega pixels of their digital cameras as compared to any other camera. Mega pixels are actually one million pixels. Pixels are small squares that form a picture on a camera screen. All the pixels have a particular color assigned to them. The pixels are building block of the picture.

Commonly, people presume that the larger is the number of mega pixels in a digital camera, the clearer the image is. This is a wrong notion. The pixels make a picture big or small. A 10,000 MP camera will not give you clearer image than an 8000 MP camera. But it will yield a larger image. So while purchasing the camera, be sure that you know how much pixels you want in your digital camera.

The sensors in your digital camera determine its efficiency. While you shop around for your digital camera, always pay attention to the types of sensors employed in it. Sensors are used to capture the image before transferring it to the main memory of the camera. This makes the camera ready to capture further images instantly.

Basically, you have two types of sensors. They are CCD and CMOS. The CCD is Charged Couple Device. It is found in expensive cameras. This sensor gives a great image quality. The other one i.e. Complementary Metal Oxide Semiconductor does not provide a good image quality. This sensor is mostly found in the cheaper cameras. If you are not a professional photographer, you can afford to buy some cheaper cameras with CMOS sensors.

The selection of a digital camera largely depends on the type of photography you like to do. The market is flooded with different varieties of digital cameras for various purposes. If you are inclined towards wild life photography, look for a camera with Center-Weighted metering. Center weighted metering is a feature by which the light reflected by the object is measured accurately with in the digital camera. The camera is focused at the center of the object.

If you are fond of nature photography, a wide angle lens and memory exposure lock is a must for you. Memory exposure is responsible for the depth of a photograph. The wide angle lens brings the depth visible. Always make sure that you carry a light camera if you are mountaineering or going for an adventure trip.

The Best Digital Cameras Product to Buy

Posted on December 2nd, 2009

: Image via Wikipedia

PowerShot A95 Digital Camera (5.0MP, 2592×1944, 3x Opt, 32MB CompactFlash Card) Strengths: High quality 5MP pictures, Camera feels great in hand, swivel LCD screen, best bang for the buck camera. Weaknesses: Included 32MB CF card is too small. Summary: This camera is awesome. I upgraded from a Canon A70 and it was well worth the money. The Canon A95 uses 4 AA bateries, but it eats through normal alkalines way too fast. I highly recommend getting rechargeable NiMH AA batteries and a quick charger.The swivel screen is a major plus, it’s 1.8″ compared to 1.5″ from the Canon A70. The screen is also higher resolution than the A70.I have used the camera for 3 weeks and printed about 50 pics so far. The pics look great and I even cropped to zoom in on some pictures and you couldn’t see any sign of pixelation. I love the manual flexibility with this camera, plus the automatic modes make it easy for anyone to use.The camera has a nice solid feel to it and fits well in the hand. I prefer the Canon A95′s size rather than the ultra compact cameras like Sony’s T1 because you can easily hold the camera in one hand and take pics. But if you have an ultra compact camera, you have to hold it awkward and it my easily fall from your hand.I highly recommend this camera to anyone looking into getting a 5MP camera that’s affordable, flexible, and normal size.

Cyber-shot DSC-W1 Silver Digital Camera (5.1MP, 2592×1944, 3x Opt, 32MB Memory Stick)

Strengths: Size, LCD, AA batteries, movie mode and black & white modes are GREAT – use ‘em all the time. Weaknesses: Flash is weak, zoom inadequate at times. Summary: I spent a LOT of time investigating digital cameras online -one would think I was buying a car or something. Anyway I am a novice camera user and remain very impressed with this little guy. I would certainly recommend it. The movie mode is great for ‘vignettes’ or small movie snapshots. I also use the black and white a lot. I also didn’t think the LCD would matter very much, but it does: I never use the viewfinder. I appreciate the large size of the LCD when passing the camera around to friends to view pictures and movies.Hint #1: Immediately jack up the megapixel resolution to 5 so that you can capture moments in the best resolution possible. Then, bypass Sony’s ridiculous profit margins- for memory cards buy SanDisk instead. The 512 MB is fantastic – you will get a lot of memory space. I saved $75.00 this way – $150 vs. $225. The 32 MB is inadequate for daily usage. I use it as ‘emergency’ memory when my 512 has filled up on me and I need an extra pinch of memory to get me through the moment.Hint #2: Do NOT buy the Sony camera case. They charge a ridiculous price for a shoddy version. Go for a Lowepro – I paid ten dollars and it is very sturdy – also has a nice inside pocket to keep memory cards.Hint #3: Buy a separate set of rechargeable batteries you can swap on the go. The AA battery format is a huge plus.Picture clarity is great for the size and price of the camera. The camera and case are small enough that I WILL take it anywhere, and have. In other words, it is a convenient model.I did find that for indoors the flash was inadequate at a distance. The zoom could also have been 4x or 5x.All in all I am quite happy with this model – but stay away from buying Sony brand ‘peripherals’ unless you like spending money.This camera fulfills my needs. The only reason it does not get five stars for the above drawbacks. Otherwise, a great job by Sony and their third-party peripheral competitors!

FinePix E550 Digital Camera (6.3MP, 4048×3040, 4x Opt, 16MB xD-Picture Card)

Strengths: Well priced, 6+mp, all features including raw image Weaknesses: This camera uses 2 AA cells in a hurry Summary: As a professional digital camera lecturer, I must admit that the Fuji E-550 was a very pleasant surprise for me. Priced at about $340, this digital camera produced digital photos that were much sharper, more detailed, and more excellent than I, frankly expected.I found the digital camera very easy to use right out of the box. While this digital camera does have a 12mp interpolated image size available, I found the 6mp native image size to have more contrast, detail and resolution.As you might expect in a consumer digital camera, the digital camera’s flash is not very powerful. At 200 ISO it will produce excellent exposures out to 13 feet. By adding a supplementary slave flash such as the Sony HVL-FSL1B and a bit of flash compensation, I was able to extend the effective flash range out to 25 feet, making the Fuji E-550 useful for indoor photos of large groups.The Fuji E-550 does an equally amazing job with macro or close-up digital photos.

It will focus quite close making it very effective for photos of small items and jewelery that might be photographed for sale on auction sites such as www.ebay.com.The strongest suit for the Fuji E-550 is it ability to record a great deal of detail with extreme sharpness and clarity while being handheld. The Fuji E-550 is also very capable of taking excellent night photos when it is placed on a tripod.All in all, I was extremely impressed with the Fuji E-550. I received a lot more digital camera than I expected for the samll price of $340. For those who like to use the raw image format, you will understand that you can essentially re-take the digital photo all over again right in your computer. This is a huge advantage.Of course, being a Fuji digital camera, the Fuji E-550 uses the somewhat more expensive XD electronic data chips.

However, the Fuji E-550 is very speedy. From power on to being ready to take the first digital photo takes 1.4 seconds. This digital camera is equally as fast in writing your digital photo to the XD chip.The newer Fuji digital cameras are marketed to compete dollar for dollar with the Kodak line of digital cameras. Therefore, they tend to be very competitive with Kodak and offer in most cases, a lot more features.There is available for the Fuji E-550 an adaptor as well as both a wide angle and a telephoto (1.9X) supplementary lens. The supplementary lenses are very fairly priced and readily available through Fuji’s own website. This is a pleasant contrast to the accessories offered by Sony, through their own website, whose wide angle and telephoto supplementary lenses are unreasonably high in price.

Conclusion: The Fuji E-550 is a top quality digital camera. It more capable than most might expect. In addition, it is quite small and pocket sized, extending its appeal to many more digital camera users. It is worthy of your attention. The digital photos produced by this digital camera are amazing and compare most favorably with much more expensive consumer digital cameras. I would happily purchase this camera again.I will be very confident in introducing the Fuji E-550 to the attendees of my workshops all over the world. It is a digital camera that I can point to with a lot of pride, simply because it gives the digital camera user many features and excellent digital photos for a very resonable price.
