I've put this in for speculation. It was shot in 1963 on a Halina 35X on a tripod for 1 second @ f5.6. Film was home processed Ferrania - remember that. I used to weigh out the chemicals at work on nights in the lab. The reason I've put it in is the ghostly figure on the left. looks to be leaning forward, has hat on and sweat towel.
It ids the casting of molten steel from an open hearth furnace.
Nothing special in itself, but that man could not have been there. He would have fried. The camera had a double exposure prevention winding device and I swear it was not contrived or fixed in any way. AP had a look at it a year or so later and could not suggest a reason.
