What is the relationship between a small f-stop and depth of field?

• A. It results in a deeper depth of field
• B. It results in a shallow depth of field
• C. It has no effect
• D. It increases exposure

Answer: (B)

A small f-stop number indicates a wide aperture opening, allowing more light to enter the camera. This wider aperture reduces the depth of field, resulting in a shallow focus on the subject while the background becomes more blurred. This effect is desirable in many types of photography, particularly portrait and macro photography, where isolating the subject from the background helps to create a more striking image. In contrast, a larger f-stop number signifies a smaller aperture, which increases the depth of field, bringing more of the scene into focus. However, since the question specifically addresses small f-stop numbers, understanding that it is associated with a shallow depth of field is essential. The other options pertain to effects that either misrepresent this relationship or focus on factors not relevant to the depth of field influence.
