What does DSLR stand for in a camera?
A DSLR camera stands for Digital Single-Lens Reflex camera. This type of camera uses a mirror and prism system to view the scene through the lens, allowing for accurate preview and control over the image. The mirror reflects the light from the lens up to the viewfinder, where the photographer can see exactly what the lens sees.
The “Digital” part of the name refers to the fact that the camera captures images electronically, rather than on film. This allows for greater flexibility and convenience, as well as the ability to review and delete photos immediately after taking them. Overall, the DSLR design provides a high level of control and accuracy, making it a popular choice among photographers.
How does a DSLR camera work?
A DSLR camera works by using a mirror and prism system to direct light from the lens to the viewfinder.
