Basic Parts of DSLR Camera and Their Functions with Pictures
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. Here we will be listing Basic Parts of DSLR Camera and Their Functions before you buy :
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.
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.
3. Mode Dial
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.
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.
5. Shutter Release
Every camera comes equipped with a shutter release button. This is simply the button on the camera that is used to snap the picture. It opens and closes the shutter, allowing the necessary light and information to enter the camera. The amount of time the shutter stays open depends on what you have your shutter speed set to. The length of time the shutter is left open or “exposed” is determined by the shutter speed.
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.

8. LCD Screen
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.
10. Focus Ring
11. Video start-stop button
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.
12. Exposure compensation button
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.

13. Mode dial
14. Flash button
15. Lens retract button
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.
16. Lens release button
Press this button to unlock the lens mount and detach the lens by rotating it. You don’t need to press it when mounting a lens.
