Why does this photo look like this?
At f/5.6 the sharp zone is much deeper, so leaves and the path behind the subject become recognisable. Less light reaches the sensor, so the shutter had to slow down.
Look at this
You can now see individual leaves. The subject no longer jumps out of the frame as strongly.
What would change with different settings
If you want the person to stand out more, step back to f/2.8 or move them further from the background.

What changed
Only the aperture changed: f/1.8 → f/2.8 → f/5.6 → f/8.
What stayed the same
Same subject, same distance, same 50mm focal length, same light. Shutter speed was made faster or slower so every frame stays equally bright.
