Are the above images showing how the measurements were taken. It looks like the meter and hand have been photoshopped in as they are in the exact same position in every photo. I assume a photo was taken of the meter at each location as the image does show the reading on the display and then overlayed on the scene. Also the angle of the hand would be reading more of what is behind the camera than the scene itself.

What are the cons of standing where the camera is to be and pointing the lux meter towards where the subject will be?
Naively perhaps, one might think that would correlate more to "lux level at sensor".
