Does depth of field change with camera-to-subject distance at the same aperture?

If I use the same aperture, for example f/1.4, how does depth of field change when I move closer to or farther from my subject? Does standing nearer give a shallower depth of field than standing farther away?

Yes. At the same aperture and focal length, depth of field gets shallower as you focus closer, and deeper as you move farther from the subject. So if you stand nearer to your subject at f/1.4, less of the scene will appear acceptably sharp.
A few related points:
- Aperture is only one factor; depth of field also depends on subject distance, focal length, and sensor/viewing conditions.
- If you move back and then crop to match the same framing, depth of field will not increase as much as it seems from distance alone.
- If you change focal length to keep the same composition, the result can be different again.
In practical terms, for stronger background blur, photographers often use a wide aperture, get closer to the subject, and keep the background farther behind the subject.
