Are the viewers human?
Yes, the viewers are human.
Is dude wearing the overalls because of some aspect of the viewing technology?
Or some aspect of his surroundings?
A combination of the two?
Because of the viewing technology, and his surroundings, which aren’t really separable in this case.
Does the viewing technology use the ordinary human-visible spectrum?
Yes.
Does this have something to do with a green screen in a television or movie studio or some similar place?
Nothing to do with green screens, but I like the way you’re thinking.
Is he in a television or movie studio (or similar)?
Shot in the dark. Is it Stooky Bill featured in John Logie Baird’s television experiments?
If not, is the issue with visibility related to television or movie technology?
Is this condition as in the terms and conditions of a contract?
Not television or movies. But you’re on the right track with entertainment.
Not terms and conditions of a contract. (“Conditions” is not a very precise term here, so don’t overthink that part.)
Stage?
Play?
Concert?
None of those.
Is our overall guy being filmed, videotaped, digitally recorded, painted by an artist, or in any other way having images of himself created?
Are the “conditions” lighting conditions?
Good one
Or photographed?
ETA: The American Gothic painting?
Phrasing carefully here… An image is being digitally created. Not American Gothic.
Digital photograph?
Not a photograph.
Did this involve a video game?
or digital imaging that was used to enhance a computer aided effect?
I’m exploring the path that the overalls were part of an outfit to track a person’s movements to be used to digitally create a character used in movies or video games.
