Viewing A Picture: He devised a sequence Camera and made series photographs of men and animals that he exhibited in motion in a viewing a picture device he called a Tachyscope. Transparencies of the photographs were mounted on the periphery of a large disk that revolved continuously behind the lens of a projector. As each picture moved into position opposite the lens, an electric flash from a Geis-sler tube threw its image on a small viewing a picture screen.A tripod is advisable because it makes it possible for you to focus and frame the picture accurately. Thereafter you need only to check the ground glass occasionally to make sure the child has not swayed out of the picture frame. Your full attention can be kept directly on the subject. You can judge those all-important subtle expressions much more quickly and accurately when looking directly at the child's face than when viewing a picture it on the groundglass.
Tion takes place in the home, on the playground, at movies, and when they are listening to radio programs, viewing a picture television, or reading comics. The time spent on radio and television, the various programs available, the favorite programs of children and youth, parents and teachers, the possible values, and the effect of television upon pupils' academic success have been studied and reviewed by Witty (174, 1958). During a week some children spend as much time viewing a picture television as they spend in school. They spend more time in viewing a picture TV than in any other single activity except sleeping. Obviously this use of time crowds out voluntary reading for some children. |
