She made the camera move in and out and around, illuminate murky recesses, magnify, induce fluorescence.

But she could see slightly glossier versions of her own fluorescence, stainless steel, ceramic island, rubber tile, pastel enamels, warm wood paneling in the Hollywood product on both Big Screen and home tube, so there she was on the set, and she had to say the lines, but after you said the lines enough times All of a sudden you'd get interrupted by something a little more direct than a commercial message from your sponsor.

With it we might be able to detect fluorescence from considerable distances, and record its density on photographic film.

There was bright fluorescence in the office and in the narrow stock room beyond the office.
