Which term describes only a thin band on the Z axis being rendered in sharp focus?

• A. Shallow Depth of Field
• B. Deep Depth of Field
• C. F-stop
• D. Aperture

Answer: (A)

Shallow depth of field describes a shot where only a thin plane along the depth (the Z axis) is in sharp focus. Everything in front of and behind that plane becomes blurred, creating that pronounced sharp subject with a soft background or foreground. This happens most when the lens is set to a wide aperture (low f-stop), which reduces the range of distances that appear sharp. A deep depth of field would keep a large range of distances in focus, not the isolated plane described here. While f-stop and aperture influence depth of field, they’re about the camera settings that create the effect, not the effect itself.
