For an aperture-based exposure workflow, which statement best describes what you do?

• A. You set the shutter speed and camera sets aperture
• B. You set the aperture and camera sets shutter speed
• C. You set ISO and camera sets aperture
• D. You set white balance and camera sets ISO

Answer: (B)

With this approach you’re controlling depth of field by selecting the aperture, while the camera handles exposure by choosing the appropriate shutter speed. This is aperture-priority workflow: you set the aperture, and the camera meters the scene and adjusts the shutter speed to achieve a proper exposure given the ISO you’ve set. The result is you get the desired depth of field and a shutter speed that fits the lighting. If you were in a different priority, like shutter-priority, you’d set the shutter speed and the camera would pick the aperture instead. If ISO were allowed to change automatically, the camera might also adjust exposure in other ways, but the essence here is: you set the aperture, the camera sets the shutter speed.
