1, 2, 3 and 4 are photographs captured using a camera with a lens set at aperture P, Q, R or S. Which of the options is/are correct?
Show Hint
Aperture size significantly affects the depth of field in photographs. Smaller apertures give a larger depth of field, while larger apertures create a blurred background.
Step 1: Understanding the aperture and its effects on the photograph.
The aperture controls the depth of field and exposure. A larger aperture (represented by a lower f-number) allows more light into the camera, resulting in a more blurred background (shallow depth of field), while a smaller aperture (higher f-number) results in greater depth of field, keeping more of the scene in focus. Step 2: Analyzing the options. (A) P - 3: This is correct as aperture P likely represents a larger aperture, creating a shallow depth of field, which matches with photograph 3. (B) P - 2: This is incorrect because photograph 2 does not exhibit a shallow depth of field, indicating a smaller aperture was likely used. (C) R - 1: This is correct as aperture R corresponds to photograph 1, which has a greater depth of field, indicating a smaller aperture. (D) S - 3: This is incorrect as aperture S likely corresponds to a medium depth of field, while photograph 3 shows a shallow depth of field. Step 3: Conclusion.
The correct answers are (A) and (C) based on the depth of field and aperture settings.
