DSLR

Definition

A DSLR, or Digital Single-Lens Reflex camera, is a type of digital camera that uses a mirror mechanism to reflect light from the camera's lens into an optical viewfinder. This design allows photographers to see exactly what the lens sees, providing a true-to-life perspective of the scene being captured, which is essential for precise framing and composition.
