“Oh, don’t bother about that. Just look at me and push the little lever. Your mind will do the rest.”

“All cameras are,” his host said mildly. “I have been photographed now by seven thousand one hundred and … eighteen … people, all with this camera, and I assure you that no two portraits are alike.” He handed the camera to Sammy, and his features, as if stamped from a machine, once more settled into the same corpulent happy mask. Sammy snapped the lever. “What possible other explanation can there be for this endless variation but interference by waves emanating from the photographer’s own mind?”
