Three shots, three sensor sizes, same picture.

Same shutter speed, aperture, and ISO. Tried to get same framing for all three. Tell me which is the full frame, crop sensor and 1". Depth of field is the biggest tell.

1=FF
2=crop sensor ??
3= 1"???
Different background color made it a tad difficult for me to decide between photos 2 and 3...

Nailed it. The little RX100VI does a great job for such a small package. Just picked it up and I really like the output.

Interesting comparison. If you really wanted us to guess though you probably should have stripped out the EXIF data.

1 FF
2 APS-C
3 1"

The physical size of sensor has no bearing on the calculation of depth of field. This is not to say that some properties of the sensor do not give rise to the ‘circle of confusion’ that does determine the depth of field. The details lie in the mathematics of the equations.

I'm sure you know you know what you're talking about, John, but for a rank amateur like me, all I know is that the the subject in the first photo stands out much more distinctly from the background than the other two.
Speaking about the "circle of confusion," you've got me circling!!

The sensor size makes a difference because the camera needs to be closer to the subject with the same lens thereby reducing depth of field. This is why FF sensors are better for portraiture if you love the bokeh effect.

Why did the wall color change so much in the third shot?

Same scene; three different pictures.

EXIF tells me. 1. - FF 134mm, 2. - APSC 93mm, 3. 1" - 48mm. Sony cameras. All 1/160, f8, ISO 100.
Were they shot with manual focus?

Top one looks FF, middle APSC and bottom 1" with WB way off. The 1" one was easy but was harder to tell between FF and APSC.
Now try the same with a well defined close subject and a distant open background (cloudless sky or distant monotone screen) - so DOF cannot easily be ascertained. :) Use an F/8 or about.
