Which three camera settings compose the exposure triangle?

• A. Aperture (f-stop), shutter speed, and ISO.
• B. White balance, ISO, and frame rate.
• C. Frame rate, shutter speed, and aperture.
• D. ISO, white balance, and color space.

Answer: (A)

Exposure is controlled by three settings that work together: aperture, shutter speed, and ISO. Aperture determines how much light enters the lens and also affects depth of field—the wider the aperture, the more light and the shallower the depth of field. Shutter speed decides how long the sensor is exposed to light, influencing motion blur or freeze—slower speeds bring in more light but can blur moving subjects, while faster speeds reduce blur. ISO changes the sensor’s sensitivity to light; higher ISO brightens the image but increases noise. Balancing these three keeps the overall exposure correct while letting you control brightness, motion, and image quality. The other options mix white balance, frame rate, or color space, which affect color or timing rather than the exposure level itself.
