Doors Closing
Cathy and I went to the storage unit today to pick up a few things, mostly related to Christmas—nativity scenes, tree decorations, the tree itself— and I decided to take a picture of the automatic doors closing. There is a slight delay after they open (which is nice, because it gives you time to get through them) and then they close. I set the camera to f/22, which gave it an exposure of 0.8 seconds at ISO 100. I moved close enough to trigger the door opening sensor, and then quickly moved back to the wall opposite and positioned the camera against the wall, with the bottom edge sitting on a piece of molding. That allowed me to hold the camera fairly steady for the long exposure. I tried opening them by voice command but all I got back was, “I’m sorry, Dave. I’m afraid I can’t do that.”
