Indicates if the battery is of Standard AA size or Proprietary type

The physical quantity of the batteries that is required for normal operation of the Digital Camera

Indicates s if the battery is of Rechargeable type or not

Rechargeable AA batteries for digital cameras are called Nickel Metal Hydride (or NiMh for short). These batteries can be recharged hundreds of times with a basic charger that costs about Rs.800/-.

The other rechargeable battery type used by digital cameras is typically a Lithium Ion pack that provides greater charge per pound than nickel metal hydride. These Li- ion battery packs usually have a custom charger that only works for that battery type. They are also only compatible with certain camera models. Lithium ion are better with frequent, shallow discharges before charging again

Audio Video interface – primarily used to interconnect audio/video equipment like VCR's, DVD players, TVs, Audio/Video receivers, Digital Cameras and more

A wireless standard for connecting cameras, PDAs, laptops, computers and cellphones. Uses very high frequency radio waves. Blue Tooth devices when in-range (less than 30 feet) of each other easily establish a connection

A new direct printing standard (DPS) for the connection of digital cameras and photo printers. With DPS you will be able to connect a compatible digital camera directly to a compatible photo printer (initially via PTP USB) and initiate prints directly from the camera - no need for a PC.

Some Photo printers usually have multiple slots to accept different types of memory cards that are used in Digital cameras too; so one can simply remove the memory card from a Digital camera, insert in the photo printer and start printing straightaway.

PictBridge is a new standard for direct USB printing from digital cameras to inkjet and dye sub photo printers without the use of a compute

Universal Serial Bus - is a plug-and-play interface for connecting a computer and add-on devices such as joysticks, keyboards, wireless phones, scanner, cameras etc.

USB supports hot-swap (ability to add a new device without having to reboot the computer). USB has a maximum bandwidth of 12 Mbps for USB 1.0 and 1.1 and 480 Mbps for Hi-Speed USB 2.0.

Wireless Fidelity - using the same IEEE 802.11b/g protocol as wireless networks for computers, digital cameras can transmit images to a computer, printer or even between cameras. As of March 2006 Canon, Kodak and Nikon have cameras with built-in WiFi capabilities

Amount of base memory that the camera comes built with. While a few cameras have internal memory to store photos, the large majority of digital cameras save photographs onto removable memory cards

When you buy your digital camera, it will only allow you to use certain types of removable media cards like xD Picture Card. Memory Stick, compact Flash card Multi Media Card, Secure Digital Card, Smart Media Card etc., While some cameras let you use two different types of cards, most only allow one. Once you know what type of media you are going to use, purchase the largest capacity card that you think you'll ever need, and use that one all the time

Indicates if the memory of a digital camera can be upgraded by using one of the many types of memory cards available for this purpose.

The operating system running in a PC with which the camera is compatible when connected to the PC. The different operating systems can be MS Windows Vista, MS Windows XP SP2, MS Windows 2000 SP4 or later, Apple Mac OS X 10.3.x - 10.4.x etc.,

In this setting, the camera automatically selects to use normal "flash" or "no flash depending on the ambient light conditions

Most compact cameras have a flash bulb that is built into the body of the camera. Some are placed on the front of the camera and others sit on top. Most digital SLRs (and a few compact cameras) have a connector - Hot Shoes - where one can attach a larger external flash to the camera

Exposure Compensation is a feature of a camera that allows one to adjust the exposure measured by its light meter. Usually, the range of adjustment goes from +2 to -2 EV in 1/3 steps.

This means that one can adjust the exposure measured by the light meter by telling the camera to allow more light in (positive exposure compensation) or to allow less light in (negative exposure compensation)

Camera shake is one of the major reasons for blurred (unsharp) images. With still cameras, camera shake is particularly problematic at slow shutter speeds or with long focal length (telephoto) lenses. With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video.

Optical image stabilization is a phrase that Panasonic uses for its stabilization system, but we use it as a general term for any camera that moves an element in the optical system to compensate for camera movement. Most cameras move a lens element, but some move the image sensor instead. The idea is simple – if the camera moves up, the lens moves down, and the net result is no movement of the image

Motion Picture Experts Group A family of standards for digital video. For video, MPEG-2 and MPEG-4 are the most common. Most popular video formats are based on one of those two technologies, with MPEG-4 being the newer, more efficient standard

In strict photographic terms, "macro" means the optical ability to produce a 1:1 or higher magnification of an object on the film or sensor. For instance if you photograph a flower with an actual diagonal of 21.6 mm so that it fills the 35mm film frame (43.3mm diagonal), the flower gets magnified with a ratio of 43.3 to 21.6 or 2:1, or with a magnification of 2X. Macro photography typically deals with magnifications between 1:1 and 50:1 (1X to 50X), while close up photography ranges from 1:1 to 1:10 (1X to 1/10X)

Many cameras have a "red eye reduction" feature. In these cameras, the flash goes off twice - once right before the picture is taken, and then again to actually take the picture. The first flash causes people's pupils to contract, reducing "red eye " significantly. Another trick is to turn on all the lights in the room, which also contracts the pupil.

Another way to reduce or eliminate "red eye" in pictures is to move the flash away from the lens. On most small cameras, the flash is only an inch or two away from the lens, so the reflection comes right back into the lens and shows up on the film. If you can detach the flash and hold it several feet away from the lens, that helps a lot

A Self timer is a device on a camera that, when enabled, gives a delay between the pressing of the shutter release and the shutter firing. It is most commonly used to allow photographers to take a photo of themselves, hence the name.

However, the self-timer mode is also often used to reduce camera shake when taking photographs in low light or with long telephoto lenses. The action of pressing the shutter release button shakes the camera to some degree. If the self-timer is used, the delay before the shutter fires allows the camera to be held more securely, or to sit without vibration on a tripod or other support.

The different types of Digital cameras can be Compact, SLR (Digital)

The amount of detail that the camera can capture is called the resolution, and it is measured in pixels. The more pixels a camera has, the more detail it can capture and the larger pictures can be without becoming blurry or "grainy."

A broad segregation of all the Digital Cameras discussed in this portal into four different segments of Resolution values (4x or Less, 4.1x - 5x, 5.1x - 7x, 7.1x or More) based on their Resolution

The lens opening formed by the iris diaphragm inside the lens

A term used to describe an auto exposure system that uses the center portion of the image to adjust the overall exposure value

A colour filter is an optical attachment placed on the front of the lens. It is used to correct color or enhance an image by absorbing parts of the visible light spectrum or create special effects through prisms and other optical enhancements

Natural light changes. It alters its color, its intensity and its direction. Sometimes the light does not want to cooperate with the mood you are trying to achieve in a photograph. Harsh light needs to be toned down for a portrait. Reflected light off water needs to be reduced for a landscape. Flower colors on an overcast day need a boost. Filters will help you do this

The three main file formats for digital photographs are RAW, TIFF and JPEG. Both RAW and TIFF formats do not apply any compression to the photo to save space on your memory card. When your camera saves a digital photo as a RAW or TIFF file (if it can), the photo includes all of the information captured by your camera's image sensor.

JPEG is a far more common file format, and it does use compression. It is a much more popular format with the consumer market because it allows a 128 MB media card to store a ton of photographs.

LCD Display or Screen size is the measure from bottom corner to opposite top corner of the viewable screen of a Digital Camera display

A broad segregation of all the Digital Cameras discussed in this portal into four different segments of LCD Size bands (2” or less, 2.1 to 2.5”, 2.6” to 3.0” and 3.1” or more) based on their LCD Size.

These are the most common viewfinders on compact digital cameras. An optical viewfinder is a little window in the camera body that sits above (and sometimes to the side) of the lens.

When you look through the viewfinder, you see an approximation of what the lens sees (and the photo that you're about to take). Since the optical viewfinder is offset from the lens, the lens covers a different area than the viewfinder.

Many optical viewfinders also have tunnel vision, and don't show you the entire scene the lens will capture. Don't be surprised if the image you see in the viewfinder is not what you see when you look at the photo later

The camera's image sensor is what captures light when the shutter opens. There are two primary types of sensors used in digital cameras today: one is called a CCD (Charge Coupled Device) and the other is called CMOS (Complimentary Metal Oxide Semiconductor).

Cameras provide the users with some creativity in terms of the kind of picture modes in different environments, such as Portrait, Landscape, Night Scenarios, Sport events etc.

The shooting modes improve the quality of images when shot for a particular situation. For example, the Portrait mode is used especially where you wish that only the subject that is being shot appears clearly, and the background gets slightly blurred so as not to distract attention

Shutter speed is the amount of time that the plate stays up or the iris stays open. Shutter speed is measured in fractions of seconds and seconds. Here is an example of shutter speed numbers, from fast to slow: 1/2000  1/1500  1/1000  1/750  1/500  1/350  1/250  1/180  1/125  1/90  1/60  1/45  1/30

The camera's auto exposure system is focused on a very small area in the center of the viewfinder to critically adjust the overall exposure value ONLY for that area

Digital zoom crops your image and magnifies the result of the cropping. This magnification process is called interpolation. To make the cropped area bigger, digital zoom makes up, or interpolates, pixels to add to the image, which may give less than satisfactory results

Optical zoom lenses physically extend to magnify your subject. A motor controls the lens movement. When you press the switch to "W" or "T," the subject is either magnified or reduced in size. The "W" stands for "wide-angle " (reduce). The "T" stands for "telephoto" (magnify).

A broad segregation of all the Digital Cameras discussed in this portal into four different segments of Zoom values (4x or Less, 4.1x - 5x, 5.1x - 7x, 7.1x or More) based on their zoom values
