The main structure of a DSLR camera consists of the following parts:
1. Lens system (lens).
2. Reflector (mirror).
3. Focus plane shutter (shutter).
4. Sensor (sensor).
5. Screen focus.

This system changes the direction of the light so that it passes through the viewfinder unit (no. 8).
When you take a photo the mirror is raised up to let light pass through it. Then the shutter (number 3) will open , light goes to position number 4 (sensor).
The shutter will continue to open until the sensor has fully captured the image, then close and the mirror returns to its original position to continue to bring light to the viewfinder.
Then in the camera a complex process occurs , the camera’s processor takes information from the sensor and then converts it into a suitable format and records it on a memory card . This whole process happens in a very short time, some professional DSLR cameras can do this process 11 times/second .
4. Advantages of DSLR cameras
1. Sensor
DSLR cameras are usually large and bulky, but because of that, the image quality will be better. DSLR cameras typically use two main types of sensors: Full-frame and APS-C (commonly known as crop-frame).
The camera is large, so the sensor size is also larger , these sensors work most effectively in low light situations. The larger the sensor , the more light it receives, the clearer your image will be.
Besides, DSLR cameras have fast, continuous, effective autofocus so they can capture any type of movement. The quality of the lens also affects the autofocus level, older lenses focus slower, but in general, a DSLR will focus faster than most other cameras.
2. Interchangeable lenses
DSLR cameras can easily change lenses to meet a variety of shooting needs. There are many types of lenses from wide-angle types for landscapes, those that specialize in capturing movement such as sports or wildlife, to wide-aperture lenses for portraiture.
Every DSLR camera comes with lenses from the manufacturer , but nowadays it’s easier for photographers as there are a number of companies like Sigma, Tamron, etc that make lenses for a wide range of purposes. DSLR camera type.

In conclusion, a DSLR camera, also known as a digital single-lens reflex camera, is a highly advanced and versatile device that offers superior image quality and greater manual control over the photographic process. Featuring a combination of digital imaging sensor and a mirror system, these cameras allow users to view the subject through an optical viewfinder, resulting in a more accurate representation of the scene. The ability to change lenses and capture images in different lighting conditions makes DSLRs a preferred choice among professional photographers and photography enthusiasts alike.
Recognizing a DSLR camera can be relatively easy once you are familiar with its distinctive features. Firstly, these cameras usually have a larger and more prominent lens protruding from the body, indicative of the ability to interchange lenses. Additionally, the presence of a mirror inside the camera body, visible when the lens is removed, serves as a significant identifying factor. This mirror reflects the light from the lens into an optical viewfinder, distinguishing DSLRs from other camera types that rely solely on electronic viewfinders or LCD screens for composition. Furthermore, DSLRs often have a robust and sturdy construction, boasting a solid grip and dedicated buttons and dials for quick access to various settings and controls.
In summary, DSLR cameras offer superior image quality, manual control, and flexibility through the lens interchangeability, making them a top choice for photography enthusiasts. Recognizing a DSLR camera can be done by observing its physical features such as the presence of a larger lens, a mirror system, and a durable build. As technology continues to evolve, DSLRs may face competition from mirrorless cameras, but for now, they remain the go-to option for professionals and those seeking the greatest creative control in their photography.
