A "Digital Back" is a device that attaches to traditional film cameras, allowing them to capture images digitally. This technology converts the camera into a digital imaging system, enabling photographers to use their existing lenses and equipment while benefiting from the advantages of digital photography, such as instant image review and easier editing. Digital backs are commonly used in professional photography, especially in fields like commercial photography and studio portraiture. They typically feature high-resolution sensors and can store images in various formats, making them versatile tools for photographers who want to maintain the aesthetic of film while enjoying digital conveniences.
