...made the TIME photograph, explains that the Finlay process renders color photography almost as simple as ordinary black & white photography. The Roosevelt picture was taken with Photo flash bulbs for lighting, with an exposure of about 1/50 sec. The colors were recorded on one special sensitized plate, placed behind a taking screen made up of hundreds of thousands of infinitesimal tri-color (red, green, blue-violet) filters which absorb part of the light and transmit the remainder to the plate. This process produces a transparency which, held to the light, shows a photograph in original color...
Besides the Finlay process, only two others produce a color photograph in one exposure on a single plate. Other processes use three successive plates behind three successive color filters...
Cadillac V16 production will be limited to 400 cars, each bearing a plate with its number and the owner's name. Cadillacs and La Salles bear distinctive labels in the upper left-hand corner of their sloping- radiators and have vacuum brake-boosters, last year available only on the two big Cadillacs...
Filled every two months, the bins discharge slowly through a s-ft. pipe into a tin pie plate as the birds empty it. The device is fastened about two feet from the ground, enclosed in natural-looking brush. Four openings are left in the brush so the birds may make a hasty exit when vermin come in. Put out on Christmas morning, one feeder was reported three days later to have attracted thousands of birds...
When the x-rays strike the copper plate they pass through the submicroscopic lattice which the copper atoms form, cast a fencelike shadow upon the screen. When Dr. Lark-Horovitz adds energy to the copper plate by heating it, electrons jump from one energy level to another in the copper atoms, and the "pickets" in the x-ray picture shift a perceptible distance. Dr. Lark-Horovitz calculates the intra-atomic movements at one 200,000,000th part of an inch...
