Resolution
?
 |
 |
|
| "Meaning: Sensor resolution is the Number of pixels used to capture an image or a video. A good image or video resolution is achieved by combination of image or video sensor resolution and lens resolution.Benefits: The Higher the image or video sensor resolution, the better the image or video quality." |

Optical Viewfinder
?
|
|
|
| Meaning: A Non-electronic device used to view the image that is being shot is known as Optical Viewfinder. Optical Viewfinders on compact cameras do not show exactly what is being shot because they are independent of the lens. The Optical Viewfinders on SLR Cameras show exactly what is being shot because they are aimed through the lens. How it functions: The Small Window generally located at the top of the camera is the optical viewfinder. Look through the Optical Viewfinder to compose yuor shot, what you see framed there is what the camera will capture. Optical viewfinders are handy for the following reason: LCD screens are hard to see in bright light, so composing your shot is hard. Advantages: Using the Optical viewfinder and turning off the LCD Screen will make your batteries last considerably longer. |

Colour Filter
?
|
|
|
| Meaning: Colour Filter is a software that modifies digital images by altering the values or arrangement of selected image pixels. How it Functions: 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 special effects through prisms and other optical enhancements. Advantages: It enhances the quality of the images taken and gives better images. |

Aperture (f/stops)
?
|
|
|
| Meaning: Aperture is the opening in a lens which passes to the image sensor to create an image. How it Functions: Aperture size is usually calibrated in f-stops. The higher the f numberthe smaller is the aperture. The common f-stops are f/2, f/2.8, f/4, f/5.6, f/8 etc. Advantages: The Quality of the image depends upon the aperture range and shutter speed of the camera. The larger the f number, the smaller the lens opening and hence less light will enter into the camera. |

Shutter Speed (Seconds)
?
|
|
|
| Meaning: Shutter priority is an exposure mode that lets you select the desired shutter speed. Shutter Speed is measured in seconds. It is the time for which the camera exposes the sensor to the light being let in by the aperture setting. How it functions: A Shutter consists of blade, a curtain, plate, or some other movable cover in a camera that controls the time during which light reaches the sensor. Many point and shoot cameras have fixed shutter speeds. Single Lens Reflex (SLR) cameras offer a greater control over the shutter speed. If you use a very slow shutter speed (about 1/8 sec) you will not be able to hold the camera in you hand and shoot the subject clearly. The Image thus obtained will get blurred. |

Sensor Type
?
|
|
|
| "Meaning: The two types of censors are CCD and CMOS. CCD - Charged Coupled Device sensor is a light sensitive chip used for Image gathering. CMOS - Coplimentary metal oxide Semiconductor is another type of image sensor found in digital cameras also.
How it functions: CCD is the most common form of photosensitive cells used to convert incoming light into electrical signals in Digital cameras. In their normal condition these are greyscale devices. To create colour, a colour pattern is laid down on the sensor pixels, using RGBG color mask. (Red, Green, Blue and Green).
Advantages: A digital image sensor converts light into electrical signals, which are then converted into an video inside the camcorder using the Camcorder video processor."

Digital Zoom
?
|
|
|
| "Meaning: Digital Zoom enlarges the subject within an image, while reducing the resolution of an image.How it functions: A Digital zoom is software inside the camera that enlarges subject in an image. Due to the doubling of pixels the image begins to become fuzzier and fuzzier as you enlarge." |

Optical Zoom
?
|
|
|
| "Meaning: Optical zoom is a feature that alters a cameras focal length, filling more of the frame within the subject.How it functions: An optical zoom lens actually moves in and out of the camera to get wide-angle, telephoto andmacro (close up) shots. Unlike a digital zoom, an optical zoom will not reduce the resolution of your photos. These days, a 3x optical zoom is pretty standard with some models going up to 10x or even 12x. Benefits: Optical zoom helps you to concentrate on the subject of the image to be shot. It is more useful in taking pictures of flowers, animals, insects etc. It also brings a faraway object nearer and hence is useful in taking photos of flora and fauna" |

Shooting Modes
?
|
|
|
| Meaning: Some cameras allow the user some creativity in terms of the kind of picture modes in different environments such as Portrait , Landscape, Night Scene and Sports etc. How it fuctions: Shooting Modes are the amount of controls you have in choosing how your digital camera captures an image. They include automatic mode, portrait mode, macro mode, landscape mode, sports mode, night mode, movie mode etc. Advantages: The shooting modes enhance the quality of images when shot as per the situation. For example, the potrait mode is used especially where you wish that only the subject that is being shot appears clearly, and the background gets slightly blurred sa as not to distract attention. |

Sunset, Dawn,Backlight, Fireworks, Beach
|
Macro Mode
?
|
|
|
| Meaning: Macro Modes allows adigital camera to take close up pictures of small objects like fingernail art, flowers, stamps, insects, etc. Macro mode is an absolute must have for shooting close up images. How it fuctions: The Macro mode enables auto focusing as close as 2cm away from the object. Many cameras offer a macro mode capable of recording images as close as 1cm also. Advantages: It is useful for taking close-ups flowers, insects and other small subjects. |

| Metering
|
Multi Metering
?
|
|
|
| Meaning: Multi Metering means when the camera measures the light intensify in several points in the scene, and then combines the result to find the settings for the best exposure. How it fuctions: This makes it possible to capture the image with the right exposure when the whole subject bright. Advantages: Multi Metering averages the exposure of the entire frame which is to be captured. |
|
|
|
|
|
|
Centre Weighted Metering
?
|
|
|
| Meaning: Centre Weighted Metering measures the brightness of the light at the centre of the frame, as well as around the centre, to calculate the correct exposurefor the image. How it fuctions: This makes it possible to capture the image with the right exposure even when the subject at the centre is bright and the background is dark. Advantages: Centered Weighted Metering averages the exposure of the entire frame but gives extra weight to the object in the centre and is ideal for taking portraits. |
|
|
|
|
|
|
Spot Metering
?
|
|
|
| Meaning: Spot Metering measures a narrow zone at the center to determine the exposure level. How it fuctions: This is useful for highlighting the subject and enhancing the visual impact, and also for capturing the details in a highlighted section. Advantages: Spot Metering allows only a small area of the whole frame to be metered and the exposure of the rest of the frame is ignored. It is the most useful for backlit, macro and moon shots. |
