Which of the following is not one of the four basic factors affecting photos?

• A. Light
• B. White Balance
• C. ISO
• D. Aperture

Answer: (B)

The idea here is to separate what controls how bright a photo is from what controls its color appearance. The four main factors that determine exposure are the amount of light reaching the sensor (the scene’s light) plus the camera’s exposure controls: shutter speed (how long the sensor is exposed), aperture (how much light passes through the lens), and ISO (sensor sensitivity). White Balance, on the other hand, handles color fidelity by adjusting the color temperature so whites and other colors look natural under different lighting. It changes color cast, not brightness, so it isn’t one of the basic exposure factors. That’s why White Balance is the correct choice.
