A viewfinder is a small device located at the top of the camera that allows the camera operator to see what the camera lens sees. It is essentially a small window that shows the image the camera is capturing, enabling the camera operator to adjust the focus, framing, and exposure.
There are two types of viewfinders: optical and electronic. Optical viewfinders use mirrors and prisms to reflect the image from the lens to the user’s eye, providing a clear and accurate representation of the image. Electronic viewfinders, on the other hand, use a small LCD screen to display the image, allowing the user to see the image in real-time with exposure, focus, and other settings applied.
In film and video production, a viewfinder is an essential tool for any filmmaker or videographer. It allows for precise composition, enabling the user to create a well-framed shot that accurately reflects their vision. A viewfinder also helps to reduce eye strain and fatigue by allowing the user to keep their eye on the subject while composing the shot.
