The AI says:

A camera is fundamentally a box (the camera body) with a lens mounted on it. This is reflected in the SVG where the large rectangle symbolizes the camera body, serving as the structure that houses the film or digital sensor, controls, and other components.

The circular shape centrally located on the rectangle represents the camera's lens. The lens is an integral part of a camera, as it focuses light onto the film or digital sensor, creating an image. The size and location of the circle effectively communicate its importance and centrality to the camera's operation.

The smaller rectangle on top represents either the camera's flash, which provides additional light when needed, or the viewfinder, through which the photographer can frame the image. Both are crucial for the use of the camera in different conditions and for different purposes.

In summary, these simple shapes and their arrangement provide a minimalist yet clear representation of a camera, capturing its essential elements and their relationship to each other in a way that is immediately recognizable.
