Hello Rajeev Ranjan, I have read your basic parts of DSLR camera and their functions article. Very nice and good explain here about DSLR camera and function. I am happy to read after this article. It’s very useful for beginner photographer. BTW, I’m a professional productbackground removal service provider for photographers and eCommerce seller.

Nice post. I understand some thing harder on diverse blogs everyday. Most commonly it is stimulating to study content using their company writers and rehearse something from their store. I’d would rather use some with the content on my weblog whether you do not mind. Natually I’ll supply you with a link on your web blog. Thanks for sharing.

The aperture affects the image’s exposure by changing the diameter of the lens opening, which controls the amount of light reaching the image sensor. Some digital compacts will have a fixed aperture lens, but most of today’s compact cameras have at least a small aperture range. This range will be expressed in f/stops. For DSLRs, the lens will vary on f/stop limits, but it is usually easily defined by reading the side of the lens. There will be a set of numbers stating the f/stop or f/stop range, ex: f/2.8 or f/3.5-5.6. This will be your lowest settings available with that lens.

DLC films are generally amorphous (i.e have no dominant crystalline lattice structure) and consist of a mixture of sp2 (graphite) & sp3 (diamond) phases. Control of film properties is strongly dependent on the flux characteristics of the chosen deposition technique (PVD sputter or evaporation and Pa-CVD), metal and hydrogen content within the film, sp2:sp3 ratio, substrate bias voltage, ion energy and ion density as well as substrate temperature. DLC film friction coefficient against steel generally ranges from 0.05-0.20, whilst film hardness and sp3 content can be tailored for specific applications. Metal and hydrogen containing DLC (Me-DLC or a-C:H:Me) exhibit hardness in the range 500-2000HV with 35% sp3, metal free DLC (C-DLC or a-C:H) typically 1500-4000HV and up to 75% sp3 , whilst tetrahedral amorphous carbon (ta-C) can be 4000-9000HV with 80-85% sp3.

Most cameras today have a variety of functions and automatic features. The mode dial allows you to select different options, such as automatic mode, program mode, sport mode or macro mode. Older cameras may not have a mode dial, because all of the settings are manual. There are also some compact cameras that use a touch-screen for selecting options instead of a dial.

Retractable lenses are becoming increasingly popular as they are more compact than non-retractable models. You must press this button to initially “zoom” the lens into its operational position, and again to retract it when you’re done shooting.

The body is the main portion of the camera, and bodies can be a number of different shapes and sizes. DSLRs tend to be larger bodied and a bit heavier, while there are other consumer cameras that are a conveniently smaller size and even able to fit into a pocket.

Choosing the best camera for amateur photographer can be difficult, so try to test several camera bodies and read professional reviews before buying an expensive camera for about $1500. A matrix size and ISO settings are the main things that show the quality of the camera body

The LCD screen is found on the back of the body and can vary in size. On digital compact cameras, the LCD has typically begun to replace the viewfinder completely. On DSLRs, the LCD is mainly for viewing photos after shooting, but some cameras do have a “live mode” as well.

The lens is one of the most vital parts of a camera. The light enters through the lens, and this is where the photo process begins. Lenses can be either fixed permanently to the body or interchangeable. They can also vary in focal length, aperture, and other details.

If you want to control aperture, you need to hold down this button. If not in manual mode, this button allows you to adjust exposure compensation — that is, make the image brighter or darker while still letting the camera make its own decisions about which settings to use to achieve that.

DLC coatings are formed when ionized and decomposed carbon or hydrocarbon species land on the surface of a substrate with energy typically 10-300eV. DLC films may possess exceptional mechanical (high hardness), optical (high optical band gap), electrical (high electrical resistivity), chemical (inert) and tribological (low friction and wear coefficient) properties and can be deposited at low substrate temperatures (~200°C).

Diamond-like-carbon (DLC) coatings are a particular area of expertise for Richter Precision Inc. Among PVD & PaCVD coating compositions and technology, DLC coatings stand out as a distinctive category. These coatings exhibit a desirable combination of a low coefficient of friction and high micro-hardness, making them extremely effective in many tribological and wear applications.

Don’t press the red button! Unless you want to shoot video, that is. This button may show up in a different position on your camera, but it is likely still decorated with a red dot. Some cameras forgo a separate record button and instead use the regular shutter button, along with a movie mode on the mode dial, for shooting videos.

The viewfinder is the area on the camera that you look through in order to compose your shot. For some cameras, an LCD screen is used as a viewfinder, or your camera may have the option to use either one. Once your photo is taken, it may not look exactly like what you see through the viewfinder. Factors such as lighting, lens, camera settings and your camera’s capabilities will affect the finished result. Because of this, the viewfinder is not intended as a preview of your photo, but rather a tool to aid you in taking it. You, as the photographer, determine the final result.

Whether you have a Digital SLRs or point and shoot , these camera parts will inevitably be found on most cameras. After getting hold of any camera, you need to know the name of the different parts before you start using it. A proper understanding of the names and functions is the primary step towards improving your photography skills.
