Slide Projector

A slide projector is a device that displays photographs or images stored on transparent slides onto a screen or wall. It works by shining a bright light through the slide, which contains the image, and then using a lens system to project a clear, enlarged image onto a surface. Slide projectors were commonly used for presentations, teaching, or sharing photos before digital screens became prevalent. They typically include controls for focusing, enlarging, and navigating between slides, offering a straightforward way to visually present static images to an audience.
