Question

adjusting the aperture of a camera lens changes the

amount of light that passes through the lens.

color temperature of the light source.

focal length of the lens.

implied proximity of the camera to the subject.

contrast of the filmed image.

Explanation:

The aperture of a camera lens is like a gate - keeper for light. A larger aperture (smaller f - number) allows more light to pass through, and a smaller aperture (larger f - number) allows less light. The color temperature of the light source is related to the type of light (e.g., tungsten, daylight), not the aperture. The focal length is related to how zoomed - in or out the lens is. The implied proximity of the camera to the subject is more about the composition and perspective, not directly the aperture. The contrast of the filmed image is influenced by factors like lighting conditions, subject matter, and post - processing, not the aperture.

Answer:

amount of light that passes through the lens.
