A DSLR stands for "Digital Single-Lens Reflex" camera. It is a type of digital camera that combines the optics and mechanisms of a single-lens reflex camera with a digital image sensor to capture images
. How a DSLR works:
- Light enters through a single lens.
- Inside the camera, a mirror reflects this light up into an optical viewfinder, allowing the photographer to see exactly what the lens sees.
- When the shutter button is pressed, the mirror flips up out of the way.
- Light then passes directly to the digital image sensor, which records the photo.
- The image is processed and saved digitally, usually on an SD card
Key points about DSLR:
- "Digital" means it uses a digital sensor instead of film.
- "Single-Lens" means the same lens is used for both viewing and capturing the image, unlike twin-lens cameras which use separate lenses for viewing and taking pictures.
- "Reflex" refers to the mirror mechanism that reflects light to the viewfinder and moves when taking the photo
DSLRs have interchangeable lenses and provide a direct optical view through the lens, offering precise framing and focusing. They differ from mirrorless cameras, which do not have the mirror and use electronic viewfinders instead
. In summary, a DSLR is a digital camera that uses a mirror mechanism to let you see through the same lens that takes the picture, combining traditional single-lens reflex design with modern digital imaging technology
