Which system uses two or more lenses and exposes one or more films simultaneously?

• A. Single Lens
• B. Multi-Lens
• C. Lens
• D. Rutter

Answer: (B)

A system that uses two or more lenses and exposes one or more films simultaneously is built to capture multiple perspectives in a single operation, enabling stereo or multi-frame mapping. This multi-lens arrangement records several images at once, which is essential for creating 3D interpretations and rapid mapping because the different viewpoints provide parallax information that helps derive elevation and shape.

A single-lens setup would only produce one image at a time, missing the simultaneous multi-perspective capability. A generic term like lens refers to a single optical element, not a complete multi-lens camera system. The remaining option does not describe a recognized multi-lens exposure system.
