What do you mean by SLR photos?

SLR photos generally refer to photos taken with SLR cameras, which can be film or digital.

SLR cameras (SLR cameras) are also called SLR cameras. Refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection.

The so-called "single lens" means that the photographic exposure light path and the framing light path * * * use one lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens. "Reflection" means that a plane mirror in the camera separates the two light paths: when the mirror falls during framing, it reflects the light of the lens to the pentaprism and then to the framing window; When shooting, lift the reflector quickly, and the light can shine on the film or photosensitive element CMOS or CCD.
