What is a DSLR Camera
A DSLR camera is a digital single-lens reflex camera that captures photos and videos in digital format and records them with the help of an electronic image sensor. In this camera, you can see it immediately after taking a photo, delete it and take a new photo in its place.
Its lenses are also very advanced and it is very different from our film camera. Its features make it unique. Its lenses and advanced features help you take a perfect picture. Let’s know how DSLR camera parts work?
How do DSLR cameras work?
When we use the viewfinder of a DSLR/DSLR When you see with an eyepiece that is located in the back of the camera, then whatever scene we see in front of us through the lens, it means that you are going to capture everything that you see.
Light from that scene comes through your camera’s lens to the relax mirror by creating a 45-degree angle on top of the camera chamber, which then forwards the light vertically to an optical element called “pentaprism.”

This pentaprism then converts that vertical light into horizontal, for which it redirects the light in two separate mirrors into a straight viewfinder.
When you take a picture, the reflex mirror swings upward, blocking the vertical pathway and allowing light to come in. Then the shutter opens up and the light reaches the image sensor.
This shutter remains open until the image sensor records the image, then the shutter closes and the reflex mirror drops back at a 45 degree angle, then it starts letting the light into the viewfinder.

It’s fair to say that this process doesn’t stop here. By the way, there is a very complicated image processing in the camera. This camera processor takes the information from the image sensor, converts it into an appropriate format, then writes it to a memory card.
This entire process takes very little time, and some professional DSLRs can do even more than 11 times more in 1 second.
In this simple language, I have provided you with information about how DSLR works.
How does modern DSLR work?
Modern DSLR cameras use a mirror and/or prism to see and focus on the subject. When we look at the object with the viewfinder, this is done with the help of a mirror and/or prism. For this, the camera has two small mirrors or mirrors.
The light rays coming through the lens reflect from the 1st mirror and fall on the 2nd mirror, and then reach our eyes through the viewfinder. Expensive DSLR cameras use pentaprism instead of the 2nd mirror, which makes the object look a little clearer.

Everyone knows how to take photos with a DSLR camera, but do you know how all its parts work? If not, let’s find out.
1. Lens
DSLR cameras have a total of three lenses. The first “standard lenses” that are no longer used. THESE LENSES WERE USED IN FILM CAMERAS WHICH WERE OF 50MM RANGE. These lenses were called standard lenses because they used to come with the camera earlier and you could not make any adjustments to them.
Then came the “kit lenses” that are now used in DSLR cameras. These lenses were designed for daily shooting so that people could click photos from it on a daily basis. The third lens is the “prime lens“, they have a fixed focal length, so they are also called fixed lenses.
Also, there is no option to zoom in or zoom out. Prime lenses are much sharper than zoom lenses. This is because they do not have extra glass inside to zoom (in or out). This gives it better quality photographs with less diffraction.
2. Reflex Mirror
The part of the camera where the reflex of an image is visible. This is a very important part of the camera. This mirror is located just behind the lens, so that the light coming from the lens falls on it and it absorbs it.
3. Shutter
This part is in every type of camera. Its job is to control the light going into the camera. The sooner the shutter closes, the less light the image will get, and the slower the shutter closes, the more light the image will get. More light makes the photo look brighter and less light makes the photo look darker.
You have to use the combination between these two so that the photo can come out perfect and well.
4. Image Sensor
Once the shutter is closed, the image sensor captures that image. The bigger the sensor, the more detail the photo will be. If the image sensor is small, then the image will be small and will not be clear in appearance.
A camera like DSLR uses a very large sensor, due to which you get a very good and perfect image.
5. Focusing Camera
This is a very important part of the DSLR camera. It can show you the preview of the photo of what you are going to take a photo of. In this, you can see the image in front of you in the View Finder whether the image is coming correctly or not.
6. Condensing Lens
It has 2 convex lenses and designing these lenses only means that the light that falls on the lens is straight and runs on a path.
7. Pentaprism
It is a five-cornered reflecting prism that bends any light at 90 degrees, whether the light is in a 90-degree prism or not. By doing this, the light falls directly on the image and the photo comes clear.
8. Eyepiece / View Finder
The part of the camera from where you view the image is the View Finder. It is like an LED glass in which you can see the photo you are going to take. With the help of the View Finder, the focus can be set on the photo well.
What is the difference between a mobile camera and a DSLR camera?
There is the same difference between a mobile camera and a DSLR camera that is between a professional and an unprofessional thing. The image sensor in DSLR is very large while in mobile camera it is very small. The bigger the sensor, the better the picture.
Having a camera of more megapixels does not do anything, the quality of the photo depends on its sensor. In terms of photos, the DSLR camera is very tremendous.
Focus in DSLRs can be done in a very spectacular way compared to mobile cameras. Apart from this, the battery life of DSLR is also much higher than mobile camera.
When did DSLR cameras appear?
At Photokina in 1986, the Japanese company Nikon revealed a prototype for the first DSLR camera, the Nikon SVC. In 1988, Nikon released the first commercial DSLR camera, the QV-1000C.
What is the price of a DSLR camera?
DSLR camera price starts from ₹35,000.
What is a full DSLR forum?
The full form of DSLR is ‘Digital Single Lens Reflex’.
