On this day in history: Edwin Land demonstrated his new Land Camera on February 21, 1947. The camera became better known by the name of Land’s company, Polaroid. It produced black-and-white photographs in 60 seconds, which at that time was considered “instant.” Cultural and artistic impact would follow. (Go here for the story.) We can celebrate this anniversary while considering the news, recently reported, that Polaroid Corp. will shut down its remaining film plants. It probably won’t take another sixty years before some new technology wipes out digital photography as we now know it. Some people say it will be 3-D photography. Other forward-thinkers are betting on some kind of holographic imagery, so we see can see our friends and family literally walking and talking in front of us, like Princess Leia in Star Wars. And it will really be instant, of course.–David Schonauer
