What type of camera allows the user to see the picture through the lens for improved composition?

A digital single-lens reflex (DSLR) camera allows the user to see exactly what the lens sees, thanks to its mirror and prism system. When you look through the viewfinder of a DSLR, you are looking through the lens and seeing a real-time optical view of the scene. This setup helps photographers achieve improved composition and makes it easier to frame their shots accurately.

In contrast, point-and-shoot cameras typically use a separate viewfinder or an electronic display that does not provide the same level of accuracy in framing, as it may not always represent what's captured in the final image. Mirrorless cameras also offer a direct view through the lens but use electronic viewfinders or displays, which may not provide the same instant feedback as a DSLR's optical viewfinder. Instant cameras, on the other hand, are designed for instant photo printing and do not offer the same level of control or viewing precision provided by DSLRs. Thus, the design of DSLRs is specifically aimed at enhancing the composition experience for the user.
