A rostrum camera is a specialized type of camera commonly used in filmmaking and photography for capturing high-quality, precise, and detailed images of two-dimensional objects. It is typically mounted on a rostrum or animation stand, which allows the camera to move vertically and horizontally above a stationary subject.
The rostrum camera consists of a vertical column with adjustable arms that hold the camera and the subject in the desired alignment. It is equipped with a sturdy base and a range of movable parts to facilitate flexible positioning and framing of the subject. The camera itself is often a high-resolution digital camera or a specialized film camera with multiple lenses and focus controls.
The primary purpose of a rostrum camera is to capture close-up shots of flat objects such as documents, maps, drawings, paintings, and photographs. It is commonly used in cinematography for shooting title sequences, credit sequences, or animating still images in documentaries or educational videos. Additionally, it is valuable in industries such as fine arts, archaeology, forensics, and document preservation, where detailed examination and reproduction of two-dimensional objects are required.
Rostrum cameras offer precise focus control, depth of field adjustment, and lighting options to ensure accurate reproduction of the subject. They also facilitate panning, zooming, and movement across the subject, allowing for dynamic visuals and highlighting specific details. The resulting images and footage captured by a rostrum camera are typically sharp, detailed, and free from distortions, making it a vital tool for capturing and studying flat objects.
