Question

what necessarily happens when a photographer chooses to give either the aperture or the shutter speed priority?
the other of the two settings is overridden.
the other of the two settings stays as previously selected.
the other of the two settings is automatically selected.
the other of the two settings is ignored.

Explanation:

In photography, when a photographer gives priority to either aperture or shutter speed (in modes like Aperture Priority or Shutter Priority), the camera automatically adjusts the other setting (the non - prioritized one) to maintain proper exposure. So the other of the two settings is automatically selected by the camera to get the correct exposure.

Answer:

The other of the two settings is automatically selected.
