Recording the iPhone 14 Pro screen with another phone, in my office, in the dark.
When the video starts you can see a phone lit up on my desk, I pan round the office anticlockwise, you can see my desk, then my chair comes into view.
The image in my test app uses the colour of the visible spectrum to show how close and object is, from purple (close), through green / yellow / orange, to red (far away)
