Questions & Step-by-Step Solutions
Which of the following combinations would result in the same exposure?
Correct Answer: All combinations can achieve the same exposure.
Step 1: Understand that exposure in photography is determined by three main factors: aperture, shutter speed, and ISO.
Step 2: Know that aperture controls how much light enters the camera. A larger aperture (smaller f-number) lets in more light, while a smaller aperture (larger f-number) lets in less light.
Step 3: Learn that shutter speed controls how long the camera's sensor is exposed to light. A faster shutter speed lets in less light, while a slower shutter speed lets in more light.
Step 4: Recognize that ISO measures the camera sensor's sensitivity to light. A higher ISO means more sensitivity (more light), while a lower ISO means less sensitivity (less light).
Step 5: Realize that you can adjust these three settings in different ways to achieve the same exposure. For example, if you increase the aperture to let in more light, you can decrease the shutter speed or lower the ISO to balance it out.
Step 6: Conclude that any combination of these settings can result in the same exposure as long as they are balanced correctly.
