Step by Step Method on How a DSLR Camera Works

I just wrote this article for those people who are wondering how a DSLR camera works and why it is more superior to a typical digital camera (point-and-shoot camera.) In this article, I listed the things that made the DSLR unique. HereĀ is a guide on how to use your DSLR camera.


A picture captured using a DSLR camera begins on the lens. DSLR lens is a variety of sub-lenses known as elements. Each lens refines and centers light to produce a high quality photograph. Lenses on Digital SLRs may be replaced for several functions. Wide angle camera lenses may be used intended for scenery. Long telephoto camera lenses may be used for sports or wildlife photography. Zoom lenses that adjust their focal length among telephoto and wide-angle are really typical, and they are usually incorporated with the digital camera.

Viewfinder, Mirror and Prism

DSLR camera is special because of their pentaprism and mirror. A mirror at the rear of the lens echoes the light towards a 5-sided prism, in which its mirrored in the viewfinder. If the shutter is pushed, the mirror at the rear of the lens turns up in order to allow a straight course between the shutter and the light. The shutter opens up for the necessary period, and the light comes in towards the sensor. In DSLRs, what a digital photographer sees in the viewfinder is almost what is taken by the sensor.

Shutter and Aperture

In DSLR, the shutter is situated in between the flip-up mirror and sensor as well as the aperture is located in the camera lens. The aperture controls by contracting and expanding, the level of light passing to the lens. The shutter regulates the quantity of light dropping to the sensor through leaving it open for a certain quantity of time. The aperture and shutter operate with each other to let an accurate quantity of light to come to the sensor.


The camera sensor is actually a matrix of small units which measure the strength and colour of the light able to come to the sensor by your shutter. These units are known as sensor sites, and they are made up of a little lens, analog to digital converter and a signal amplifier. The caliber of the ultimate picture is mainly one factor of sensor quality.

In-Camera Processing

As soon as the picture has been taken with the sensor and converted to digital, fundamental picture processing is performed inside the camera. This might consist of eliminating noise and grain normal while in the sensor, modifying levels to user preference, along with other basic things that do not call for the potential of your PC. More contemporary DSLRs have more impressive computers that enable more complicated in-camera developing such as changing a picture from colored to monochrome.

Memory Card

After picture developing, the graphic is saved over a memory card for future access through computers. Flash memory is utilized since it does not need capacity to save a picture. Typical memory cards are SD, XD and Compact Flash. After a picture is on the storage device, it could be read by every computer having a proper card reader. Many DSLRs make use of Compact Flash or SD card.
