DSLR is an abbreviation for “Digital Single Lens Reflex”. In simple terms, the word “DSL” refers to “Digital Single Lens Reflex”. DSLR is an electronic digital camera which makes use of mirrors which reflect light from the lens of a camera to an optical viewfinder (which serves as an optical eyepiece that is located at the rear of the camera that can be used to view the subject being photographed) and let the light be completely absorbed through an imaging sensor (which captures the image) by moving the mirror away from the way. Although single lens reflex cameras have been in various forms and designs from the beginning of the 19th century, film was the primary method of recording. The first digital SLR commercially that had an integrated image sensor released in 1991. In contrast to point-and shoot and cellphones, DSLR cameras typically use interchangeable lenses.

2) How DSLR Cameras Work
When you gaze at your DSLR eyesight or viewfinder located on the back or the back of the camera, the image you see is reflected by the lens that is connected to your camera. It is possible that you are seeing precisely what you want to capture. The light of the scene you wish to record passes through the lens and onto its reflector (#2) which is situated at an angle of 45 degrees inside the lens chamber of the camera. The lens then reflects that light vertically onto an optical component referred to as”pentaprism. “pentaprism” (#7). The pentaprism converts horizontal light from vertical by passing sunlight through mirrors and later through lenses (#8).
If you’re making a photo, the reflex mirror (#2) shifts upwards to block the vertical path and let light pass flow through. A shutter (#3) is opened, and the light is directed toward the photo sensor (#4). The shutter (#3) remains open for the period of time needed to allow the image sensor (#4) to take the image. Following that, it shuts. (#3) is shut down and that mirror (#2) is lowered at its 45-degree angle, which allows it to direct light towards the viewfinder.
Naturally, it doesn’t stop at that point. Then, many intricate processing of images happens inside the camera. The camera processor gathers information of the camera’s sensor. It converts it into the proper formats, and then writes it onto your memory card. The whole process is quick, and certain high-end DSLRs can finish the process more than 11 times per second!
This is a brief explanation of how DSLR cameras work.
