Which components are part of the exposure triangle?

The exposure triangle consists of three key components that control the exposure of an image: aperture, shutter speed, and ISO. Each of these elements has a distinct role in determining how light is captured by the camera sensor.

The correct choice highlights shutter speed, which governs how long the camera's shutter remains open to let in light. A faster shutter speed allows for less light to hit the sensor, which is ideal for capturing fast-moving subjects without motion blur. Conversely, a slower shutter speed allows more light in, which can create a motion blur effect or overexpose the image if not managed carefully.

The mention of film speed references ISO, which measures the sensitivity of the camera sensor to light. A higher ISO allows for better performance in low light conditions but can introduce graininess or noise into the image. Conversely, a lower ISO produces cleaner images but requires more light.

F/stops relate directly to aperture, which controls the size of the lens opening. A wider aperture (lower f-stop number) lets in more light, contributing to a brighter image and affecting depth of field, while a smaller aperture (higher f-stop number) allows less light and increases the depth of field.

Together, these three components (aperture, shutter speed, and ISO
