A camera is a device that captures visual images or videos by using the principles of optics and light-sensitive sensors. It allows users to record and preserve moments, whether they are professional photographers documenting scenes or individuals capturing memories. Cameras come in various types, including digital cameras, DSLRs, mirrorless cameras, and smartphone cameras, each offering different features and capabilities. They enable people to explore their creativity, express themselves visually, and share their perspectives with others. The iconic symbol "📷" represents a camera and is often used to indicate or refer to photography-related content.
