My essay:

The diagram illustrates the optical elements of the digital Single-Lens Reflex (SLR) camera.

Overall, it is patently obvious that the camera consists of two main sections: a series of lenses and mirrors for viewing scenes before shooting. A data processing component for capturing and image processing. At the first stage of the process, when the shutter button at the top of the camera is clicked, light from the object also passes through four convex lenses of varying sizes, which is mounted on a common panel with the viewing lens. After that, the shutter closes and the reflex mirror drops back to 45 degrees diagonally inside the body chamber to continue redirecting the light into the viewfinder. In addition, the image is reaches onto the screen allows the photographer to view through the lens and see exactly what will be captured.

The next step begins when the shutter is pressed, the flat mirror is swung upwards, and no longer blocks the incoming light. As a result, the light that passes through the lens and then to a mirror that alternatives to sending image goes directly to the CMOS sensor. This step is followed by the scene is recorded into a digital image. Coming to the final stages of the process, the image is subsequently processed via a mini CPU and sent directly to the memory card, and is displayed on the LCD screen.
