Boyle and American George E. Smith, who both worked at Bell Labs in Murray Hill, New Jersey, for inventing the so-called charge-coupled device semiconductor -- better known as a CCD. Any one who has ever looked at a digital camera spec list must have seen CCD.<br />Another pioneer is Eric R. Fossum, whose development of the CMOS (complementary metal-oxide semiconductor)image sensor, or camera on a chip, in the early 1990s has had a profound effect on digital imaging technology. It found uses in Web cams, cell phone cameras, high-end digital single-lens-reflex cameras, swallowable medical pill-cameras, automotive and space exploration applications. <br /></li><li> 4. HOW DIGITAL CAMERAWORKS<br />A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that uses a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder at the back of the camera.<br />The basic operation of a DSLR is as follows: for viewing purposes, the mirror reflects the light coming through the attached lens upwards at a 90 degree angle. It is then reflected twice by the pentaprism, rectifying it for the photographer's eye. During exposure, the mirror assembly swings upward, the aperture narrows, and a shutter opens, allowing the lens to project light onto the image sensor. A second shutter then covers the sensor, ending the exposure, and the mirror lowers while the shutter resets. The period that the mirror is flipped up is referred to as "viewfinder blackout". A fast-acting mirror and shutter is preferred so as to not delay an action photo.<br />All of this happens automatically over a period of milliseconds.<br /></li><li> 5. </li><li> 6. ACCESSORIES<br />LENS<br />Photography is all about capturing light on a photographic emulsion or electronic sensor. So a photographic lens is very important.<br />A photographic lens is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film, or on other media capable of storing an image chemically or electronically.<br /></li><li> 7. ACCESSORIES<br />LENS<br />A lens may be permanently fixed to a camera, or it may be interchangeable with lenses of different focal lengths, apertures, and other properties.<br /></li><li> 8. ACCESSORIES<br />LENS HOOD OR LENS SHADE<br />In photography, a lens hood or lens shade is a device used at the end of a lens to block the sun, or any other light source in order to prevent glare and lens flare.<br /></li><li> 9. ACCESSORIES<br />TRIPOD AND CAMERA CLAMP<br />Tripods are used for both motion and still photography to prevent camera movement and give stability. They are necessary when slow-speed exposures are being made, or when telephoto lenses are used, as any camera movement while the shutter is open will produce a blurred image. In the same way, they reduce camera shake, and thus are instrumental in achieving maximum sharpness. A tripod is also helpful in achieving precise framing of the image, or when more than one image is being made of the same scene<br /></li><li> 10. ACCESSORIES<br />LIGHT METER<br />A light meter is a device used to measure the amount of light. <br />In photography, a light meter is often used to determine the proper exposure for a photograph. <br />Typically, a light meter will include a computer, either digital or analogue, which allows the photographer to determine which shutter speed and f-number should be selected for an optimum exposure, given a certain lighting situation and film speed.<br /></li><li> 11. ACCESSORIES<br />STUDIO LIGHTING KIT<br />Studio lighting kits are a great way to get started in studio lighting. If you have the resources, it is best to purchase a lighting kit that has everything you need together in one place. Many manufacturers also include carrying cases and protective containers for your gear as a part of the kit.<br /></li><li> 12. ACCESSORIES<br />FLASH, FILTER &amp; MEMORY CARD<br />Flash, filters and memory cards are optional. It comes with many variation which is subjective to the photographic need.<br />A flash is a device used in photographyproducing a flash of artificial light at a color temperature of about 5500 - 6500 K to help illuminate a scene. A major purpose of a flash is to illuminate a dark scene.<br />A filter is a camera accessory consisting of an optical filter that can be inserted in the optical path.<br />A memory card or flash memory card is a solid-state electronic flash memory data storage device capable of storing digital contents. The primary use is with digital cameras.<br /></li><li> 13. TIME WARP AND <br />UNDER WATER PHOTOGRAPHY<br />Time Warp or High speed photography is the science of taking pictures of very fast phenomena. High speed photography can be considered to be the opposite of time-lapse photography.<br />Underwater photography is the process of taking photographs while under water. It is usually done while scuba diving, but can be done while snorkeling or swimming.<br /></li><li> 14. TIME WARP AND <br />UNDER WATER PHOTOGRAPHY<br />Underwater imaging is considered an especially challenging area of photography, since it requires very specialized equipment and techniques to be successful.<br /></li><li> 15. TIPS<br />Move in closer to the subject<br />2.Focus on your subject &amp; Lock it<br />3.Compose your scene with care<br />4.Keep it simple<br />5.Use Tripod<br />6.Hold camera correctly<br />7.Act according to light conditions<br />8.Experiment with setups<br />9.Look and care for background <br /></li><li> 16.
