Lamps
Two lamps beside the easel
One lamp on pinning the elevation before the throw moves. One lamp on a caption slat as a field. Not a press room and not a case-study wall.
The elevation is pinned before the lamp moves
A stop-write on the elevation is easier to hand to the next reader than a spoken request to raise the lamp.
A caption slat is a field, not a promise
URLs that open, and a caption that matches what the file actually does, matter more than extra adjectives.
