The extruder is a large machine similar to the Play-Doh extruder many of us played with as children. It is longer than a large tractor-trailor truck, and when it is in operation it wheezes and clanks and puffs. Before I could photograph well here, I had to learn what everything and everyone did. This was the first successful shot I took that understands what's happening here. It is quiet and idealized. I've taken the same shot in full action.
