Digital Cameras Archives
Digital cameras, which employ reusable memory cards instead of film, give you far more creative control than film cameras can. With a digital camera, you can transfer shots to your computer, then crop, adjust color and contrast, and add textures and other special effects. Final results can be made into cards or T-shirts, or sent via e-mail, all using the software that usually comes with the camera. You can make prints on a color inkjet printer, or by dropping off the memory card at one of a growing number of photofinishers. You can upload the file to a photo-sharing Web site for storage, viewing, and sharing with others.
Like camcorders, digital cameras have LCD viewers. Some camcorders can be used to take still pictures, but a typical camcorder’s resolution is no match for a good still camera’s.
WHAT’S AVAILABLE
The leading brands are Canon, Fujifilm, HP, Kodak, Olympus, and Sony; other brands come from consumer-electronics, computer, and traditional camera and film companies.
Digital cameras are categorized by how many pixels, or picture elements, the image sensor contains. One megapixel equals 1 million picture elements. A 3-megapixel camera can make excellent 8×10s and pleasing 11×14s. There are also 4- to 8-megapixel models, including point-and-shoot ones; these are well suited for making larger prints or for maintaining sharpness if you want to use only a portion of the original image. Professional Digital cameras use as many as 14 megapixels.
Price range: $200 to $400 for 3 megapixels; $250 to $400 for 4 and 5 megapixels; $300 to $1,000 for 6 to 8 megapixels.
IMPORTANT FEATURES
Most Digital cameras are highly automated, with features such as automatic exposure control (which manages the shutter speed, aperture, or both according to available light) and autofocus.
Instead of film, digital cameras typically record their shots onto flash-memory cards. CompactFlash and SecureDigital (SD) are the most widely used. Once quite expensive, such cards have tumbled in price–a 128-megabyte card can now cost less than $50. Other types of memory cards used by cameras include Memory Stick, Smart Media and xD-picture card. A few cameras, mainly some Sony models, use 3 1/4-inch CD-R or CD-RW discs.
To save images, you transfer them to a computer, typically by connecting the camera to the computer’s USB or FireWire port or inserting the memory card into a special reader. Some printers can take memory cards and make prints without putting the images on a computer first. Image-handling software, such as Adobe Photoshop Elements, Jasc Paint Shop, Microsoft Picture It, and ACDSee, lets you size, touch up, and crop digital images using your computer. Most digital cameras work with both Windows and Macintosh machines.
The file format commonly used for photos is JPEG, which is a compressed format. Some cameras can save photos in uncompressed TIFF format, but this setting yields enormous files. Other high-end cameras have a RAW file format, which yields the image data with no processing from the camera.
Digital cameras typically have both an optical viewfinder and a small color LCD viewer. LCD viewers are very accurate in framing the actual image you get–better than most of the optical viewfinders–but they use more battery power and may be hard to see in bright sunlight. You can also view shots you’ve already taken on the LCD viewer. Many digital cameras provide a video output, so you can view your pictures on a TV set.
Certain cameras let you record an audio clip with a picture. But these clips use additional storage space. Some allow you to record limited video, but the frame rate is slow and the resolution poor.
A zoom lens provides flexibility in framing shots and closes the distance between you and your subject–ideal if you want to quickly switch to a close shot. The typical 3x zoom on mainstream cameras goes from a moderately wide-angle view (35mm) to moderate telephoto (105mm). You can find cameras with extended zoom ranges between 8x and 12x, giving added versatility for outdoor photography. Other new cameras go down to 24 or 28 mm at the wide-angle end, making it easier to take in an entire scene in close quarters, such as a crowded party.
Optical zooms are superior to digital zooms, which magnify the center of the frame without actually increasing picture detail, resulting in a somewhat coarser view.
Sensors in digital cameras are typically about as light-sensitive as ISO 100 film, though some let you increase that setting. (At ISO 100, you’ll likely need to use a flash indoors and in low outdoor light.) A camera’s flash range tells you how far from the camera the flash will provide proper exposure: If the subject is out of range, you’ll know to close the distance. But digital cameras can tolerate some underexposure before the image suffers noticeably.
Red-eye reduction shines a light toward your subject just before the main flash. (A camera whose flash unit is farther from the lens reduces the risk of red eye. Computer editing of the image may also correct red eye.) With automatic flash mode, the camera fires the flash whenever the light entering the camera registers as insufficient. A few new cameras have built-in red-eye correction capability.
Some cameras that have powerful telephoto lenses now come with image stabilizers. These compensate for camera shake, letting you use a slower shutter speed than you otherwise could for following movement. But an image stabilizer won’t compensate for the motion of subjects.
Most new 6- to 8-megapixel cameras come with full manual controls, including independent controls for shutter and aperture. That gives serious shutterbugs control over depth of field, shooting action, or shooting scene with tricky lighting.
HOW TO CHOOSE
The first step is to determine how you will use the camera most of the time. Consider these two questions:
How much flexibility to enlarge images do you need? If you mainly want to make 4×6 snapshots, a camera with a 3- or 4-megapixel resolution will be fine. Such a camera will also make an 8×10 print of an entire image without alteration that looks as sharp as one from a 6- or 8-megapixel model. But to enlarge the image more or enlarge only part of it, you’ll want a 6- to 8-megapixel camera.
How much control do you want over exposure and composition? Cameras meant for automatic point-and-shoot photos, with a 3x-zoom lens, will serve snap shooters as well as dedicate hobbyists much of the time. The full-featured cameras in the 6- to 8-megapixel range offer capabilities that more-dedicated photographers will want to have. Two of the more important capabilities are a zoom range of 5x to 10x or more, which lets you bring distant outdoor subjects close and also lets you shoot candid portraits without getting right in your subject’s face, and a full complement of manual controls that you determine the shutter speed and lens opening. ‘
Once you’ve established the performance priorities that you need from a camera, you can narrow your choices further by considering these convenience factors:
Size and weight. The smallest, lightest models aren’t necessarily inexpensive 3-megapixel cameras. And the biggest and heaviest aren’t necessarily found at the high end. If possible, try cameras at the store before you buy. That way, you’ll know which one fits you hand best and which can be securely gripped. In our tests, we have found that some of the smallest don’t leave much room even for small fingers.
Battery type and life. All digital cameras can run on rechargeable batteries of one of two types: an expensive battery pack or a set of AA batteries. In our tests of the cameras, neither battery type had a clear performance advantage. The best-performing cameras offer upward of 300 shots on a charge, while the worst manage only about 50. We think it’s more convenient to own a camera that accepts AA batteries. You can buy economical, rechargeable cells (plus a charger) and drop in a set of disposable lithium or alkaline batteries if the rechargeable run down in the middle of the day’s shooting.
Camera speed. With point-and-shoot cameras like the ones we tested, you must wait after each shot as the camera processes the image. Most models let you shoot an image every few seconds, but a few make you wait 5 seconds or more. They may frustrate you when you’re taking photos in sequence.
Your other cameras. If you’re adding a camera to your lineup or trading up to a more versatile model, look first for one that’s compatible with the other cameras. If it is, you can share memory cards and batteries. Designs within a camera brand line are often similar. So staying wit the brand you have lowers the learning curve on the new camera for family members who switch between cameras.

Product Description
The QMM1 is a new macro twin flash mount system designed to give flash support that is flexible, compact and easy-to-use. It can be either hand-held or mounted on a tripod. The QMM1 has a sturdy base plate machined from aircraft grade aluminum that can hold up to years of use. It has a 1/4-20 camera screw in the base plate that can mount almost any digital SLR camera. Permanently attached to the base plate of the QMM1 are two fully articulating arms made from high-quality ultra lightweight flex-conduit. These arms allow flash units to be positioned at almost any angle around the subject for a wide variety of lighting effects. Ball joints supporting the flash units allow for even greater control of the flash position and angle. In addition, there is one 1/4 -20 treaded mount point on either side of the QMM1 to attach other accessories. Unlike a ring flash that is fixed on the camera lens yielding flat lighting, the QMM1’s ability to move the flash units creates directional light that can add greater depth, definition and attention to macro subjects. This gives the photographer greater control to create the image they want. The QMM1 is designed and assembled in the USA.

There have been many products that are turning out to be the premier gateways for having a good time. Some of them are
1.Televisions
2.Digital cameras
3.Video camera
4.Music systems
5.Gaming consoles etc.
However, some of the products out of the above mentioned list are ones that are becoming into highly versatile products. One of them is the digital camera which by virtue of its features is creating an ever growing fan base and that too a global one.
There are many well known companies in the world that have created a name for themselves in the art of making digital cameras. Some of them are
1.Nikon
2.Cannon
3.Casio
4.Ricoh
5.Pentax
6.Aigo
7.Sigma
8.Samsung
9.Sony
10.Vivitar
11.Panasonic
One has to take a detailed look into the features of any one of the cameras made by any one of these brands in order to have a full idea about their excellence.
Hence, let the example be none other than a camera created by the company Panasonic. This camera is produced under the brand name Lumix and is known as the DMC-ZS3S.
Some of the features of this camera are as follows:
1.LEICA DC VARIO-ELMAR lens which is nothing but a combination of
1.2 Aspherical Lens
2.2 ED lens
3.3 Aspherical Lens
2.AS Assist Lamp
3.High sensitivity mode (automated)
4.White balance which is effective for taking pictures under
1.Daylight
2.Cloudy conditions
3.Shade etc.
5.Multiple scene modes with some of them being
1.Scenery
2.Sports
3.Night Portrait
4.Night Scenery
5.Candle light
6.Sunset
7.Snow
8.Beach
9.Fireworks
10.Starry sky etc.
6.4 x digital zoom
7.Highly capable image sensor
8.Optical zoom of 12 x.
9.Resolution: 10.1 MP
10.Intelligent Scene selector
11.Face detection
12.Face recognition etc.
This example is quite capable of giving one an idea as to how advanced digital cameras have become nowadays. However, apart from being advanced, they have also become user friendly at the same time.
Therefore, an improvement in the features and their corresponding technologies has not led to a reduction in the user friendliness of these cameras.
This has led to an improvement in the demand for this products and this improvement has taken place on a global scale.
The companies that have been mentioned above are all engrossed in making their products even better with every passing day. Therefore, the customer can expect a higher level of technologies and features in the days to come.
This is one of the primary developments that has taken place today with another important one being the change of the place from where digital cameras are normally bought.
Actually, the users have been given a wonderful option in the form of a shopping website. Online shopping has become a reality all over the world with B2C transactions having their best time ever.
Online shopping in India has also taken place on a magnificent scale and it has, therefore, led to the establishment of many shopping websites. Digital cameras, therefore, are now being sold on many websites in the Indian sub continent.
There have been many reasons behind the growth of online shopping in India and one of them has been an effective implementation of the concept of social shopping.
This is one of the concepts that has helped people to know about the features of all those highly complicated digital cameras. Hence, that element of apprehension (while undertaking an online purchase) which was there earlier is now normally made to hear its death knell in the most effective manner possible.
