Final answer:
The SEESAW analogy between aperture and shutter speed in photography can be explained as the opposite movement and the need for balance.
Step-by-step explanation:
The SEESAW analogy between aperture and shutter speed in photography can be explained as follows:
- Similar Movement: Just like a see-saw, where one end goes up as the other end goes down, aperture and shutter speed work in opposite directions. When you increase the aperture size to let in more light, you need to increase the shutter speed to capture the image quickly and prevent motion blur. Similarly, when you decrease the aperture size to let in less light, you need to decrease the shutter speed to allow more time for light to reach the sensor.
- Balance: The see-saw analogy also highlights the need for balance. To achieve a proper exposure, you need to find the right combination of aperture and shutter speed. If you increase one, you may need to adjust the other to maintain the correct exposure.
For example, if you're taking a photo in low light conditions and you want a shallow depth of field, you would increase the aperture size to let in more light. To prevent motion blur, you would need to increase the shutter speed as the aperture size increases. On the other hand, if you're shooting in bright light and want a larger depth of field, you would decrease the aperture size, which would require a slower shutter speed to compensate for the reduced light.
