In photography, a term for the opening that permits light to enter?

Explanation:
In photography, the opening that lets light into the camera is the aperture. It’s the adjustable opening inside the lens (often called the diaphragm) that controls how much light reaches the sensor. The size of the aperture also affects depth of field: a larger opening (smaller f-number) lets in more light and gives a shallower depth of field, while a smaller opening (larger f-number) lets in less light and increases depth of field. Terms like doorway or window belong to buildings, and a cavity is a generic hollow space—so they don’t describe the camera’s light-gating element.
