Same lens and distance, aperture only. Portraits often use f/1.4–2.8 for a shallow focus; landscapes f/8–11 for front-to-back sharpness.

FAQ
How is depth of field calculated?
From focal length, aperture, focus distance and the sensor's circle of confusion. A 50 mm lens at f/2.8 focused at 10 ft on full frame is sharp from about 9.08 ft to 11.1 ft.
How much deeper is depth of field when I stop down?
Doubling the f-number (f/2.8 → f/5.6) roughly doubles depth of field. Past about f/16, diffraction softens the whole image.
What is hyperfocal distance?
Focus at the hyperfocal distance and everything from half that distance to infinity is sharp. For 24 mm at f/11 on full frame it is about 5.8 ft.
Do crop sensors have more depth of field?
At the same framing and f-number, yes — a crop body uses a shorter focal length, so depth of field is deeper. Switch the sensor to compare.
How do I get a blurrier background?
Open the aperture, use a longer focal length, get closer to your subject and put more distance between subject and background.

How to calculate depth of field

Depth of field is the zone in front of and behind your focus point that looks acceptably sharp. It gets shallower with wider apertures, longer lenses, closer focus and larger sensors at the same framing.

This calculator uses a circle of confusion matched to your sensor to find near and far limits and the hyperfocal distance, and compares depth of field across apertures.
