BASIC PARTS OF CAMERA1. Body - Made of high grade plastic or metal, this holds all the other parts together as well as provide protection to the delicate internal parts of the camera.

2. Lens - A proper term for this part should be Lens Assembly, this consists of several layers of lenses of varying properties providing zoom, focusing, and distortion correction. These lenses are mechanically interconnected and adjustment is controlled electronically by the camera's body.3. Shutter Release Button - This is the "trigger" of the camera. In most cameras, a half-press activates and locks the auto-focus, and a full press initiates the image capturing process.4.Image Sensor-An image sensor is a device that converts an optical image into an electronic signal. It is used mostly in digital cameras, camera modules and other imaging devices.5. Viewfinder - A small viewing window that shows the image that the camera's imaging sensor sees. This can either be an optical view finder, which shows the actual image in front of the camera through a peep hole or through mirrors, or an electronic view finder which is simply a small LCD display.6. Aperture Ring - Found around the old manual lens of SLR camera this is used to select an aperture opening. In modern lenses, the aperture is controlled electronically through the body.7. LCD Display - In some compact cameras this acts as the viewfinder. This is a small screen (usually 1.8" diagonally or bigger) at the back of the camera which can be used for framing or for reviewing the recorded pictures.8. Flash - Built-in on the body of most compact and some DSLR cameras this can either be fixed or flip type, it provides an instantaneous burst of bright light to illuminate a poorly lit scene.9. Control Buttons - Usually includes a set of directional keys and a few other buttons to activate certain functions and menus, this is used to let users interact with the camera's computer system.10. Memory Card Slot - This is where expansion memory cards are inserted. The proper position of the card are often indicated. A mechanical catch usually holds the card in place and a spring helps it eject.

USING CAMERA

TROUBLESHOOTINGTroubleshooting is a form of problem solving, often applied to repair failed products or processes. It is a logical, systematic search for the source of a problem so that it can be solved, and so the product or process can be made operational again. Troubleshooting is needed to develop and maintain complex systems where the symptoms of a problem can have many possible causes. Troubleshooting is used in many fields such as engineering, system administration,electronics, automotive repair, and diagnostic medicine. Troubleshooting requires identification of the malfunction(s) or symptoms within a system. Then, experience is commonly used to generate possible causes of the symptoms. Determining the most likely cause is a process of elimination - eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state.

In general, troubleshooting is the identification of diagnosis of "trouble" in the management flow of a corporation or a system caused by a failure of some kind. The problem is initially described as symptoms of malfunction, and troubleshooting is the process of determining and remedying the causes of these symptoms.

A system can be described in terms of its expected, desired or intended behavior (usually, for artificial systems, its purpose). Events or inputs to the system are expected to generate specific results or outputs. (For example selecting the "print" option from various computer applications is intended to result in a hardcopy emerging from some specific device). Any unexpected or undesirable behavior is a symptom. Troubleshooting is the process of isolating the specific cause or causes of the symptom. Frequently the symptom is a failure of the product or process to produce any results. (Nothing was printed, for example).Corrective action can then be taken to prevent further failures of a similar kind.

The methods of forensic engineering are especially useful in tracing problems in products or processes, and a wide range of analytical techniques are available to determine the cause or causes of specific failures. Corrective action can then be taken to prevent further failure of a similar kind. Preventative action is possible using failure mode and effects (FMEA) andfault tree analysis (FTA) before full scale production, and these methods can also be used for failure analysis
