In the common f/stop range of f/2 to f/22, which setting represents the shortest depth of field (DOF)?

The setting that represents the shortest depth of field (DOF) among the given options is f/2. Depth of field refers to the range of distance within a photo that appears acceptably sharp. A wider aperture, indicated by a smaller f-stop number, creates a shallow depth of field.

When using f/2, the aperture is wide open, allowing a significant amount of light to enter the camera. This results in a short depth of field, which effectively isolates the subject from the background, creating a pleasing bokeh effect. It is ideal for portrait photography where the subject is emphasized, and the background is made less distracting.

In contrast, as f-stop values increase, such as f/5.6, f/11, and f/22, the aperture becomes smaller, narrowing the opening through which light passes. This leads to greater depth of field, meaning more of the scene will be in focus. Therefore, f/2 is the setting that yields the least depth of field, emphasizing the subject while softening the surrounding elements.
