A whole "frozen shadow" room--wow! Now I've learned something. In our museum's now-defunct Hall of Photography we had only a "frozen-shadow" COUNTER, and we thought we were so original! We called it "The Lingering Shadow," and the point was to demonstrate both high-speed electronic flash as well as the temporary photographic effect. A long, narrow counter at table height with flash units above, its images were usually just visitors' hands (occasionally feet, for the more adventurous--and I hope no one ever got any more adventurous with body parts), so it was literally a hands-on exhibit. That reminds me of a story, about the flash, not the shadows--I think I've related it before, a couple of years ago, so Museum-L veterans, please bear with me. One day Harold Edgerton, the inventor of electronic flash, came to visit, so I showed him the display while a solitary teenage girl was concentrating on making creative hand-print designs with it. He caught her attention and, with a mischievous grin, pulled a postcard out of his pocket and thrust it at her. It had a reproduction of one of his famous frozen milk-drop pictures. Since she looked confused and a bit alarmed, as if a dirty old man were showing her dirty pictures, I jumped in and said, "This is Dr. Edgerton. He invented electronic flash." She gaped at the picture, then at him, and yelped, "Oh, wow!" It really made his day. His memory lives on in your frozen shadow rooms.
