viewfinder

A viewfinder is the part of a camera or video camera that helps you see and frame what you are about to photograph or film. It may be a small window that you look through or an electronic screen that shows the scene before you press the shutter or start recording. In everyday use, this is what the word usually means: a practical tool for choosing the shot and lining things up clearly.

The word "viewfinder" is mainly used for the part of a camera, camcorder, or similar device that shows the scene and helps the user decide how the final image will look. It gives a limited view of what is in front of the lens, making it easier to frame a subject, adjust composition, and choose what stays inside or outside the picture. Some viewfinders are optical, meaning you look through a small eyepiece. Others are electronic and show a digital preview on a tiny display.

In photography and filmmaking, this is an important working tool because it guides the shot before the picture is taken. The exact design can vary from one device to another, but the basic idea stays the same: it helps you aim, frame, and focus your attention on the scene.

The word is also sometimes used more loosely in a figurative way for a way of looking at something, but that use is much less common than the camera meaning. Most of the time, if someone says "viewfinder," they mean the viewing part of a camera.
