The Audio-Visual Handbook
"The stereograph is, therefore, a photograph of an actual situation in life, not an artificial creation or stage setting built up for a special occasion. The lens of the camera in this case acts as an unprejudiced,
mechanical eye. In studying a great painting we are able to see only what the artist visualized and reproduced on his canvas. The study of the stereograph is almost unlimited. Each time it is viewed, some interesting detail far off in the distance is revealed.
"Through these interesting devices the great wonders of nature in the remotest parts of the earth are brought truthfully and vividly before us, and great personalities of history, like McKinley, or Roosevelt, or Wilson seem so real that we almost expect them to open their lips and speak. This element of truthfulness brings joy and delight to both old and young."*
za"" Advantages: The stereograph, as suggested in the foregoing, presents to the pupil a more nearly true concept of the object, person, or situation than could be obtained through the use of any other type of picture. The pupil is actually transported to the place where the picture was taken and sees the picture with a sense of being present.
The stereograph is inexpensive, costing only about twenty -one cents for each view. Furthermore, there is an unlimited supply of excellent stereographs available. One large organization** has devoted many years to the preparation of stereoscopic views of all parts of the world, including many excellent pictures for nature study of various types.
Limitations: The stereograph is an individual rather than a group
teaching tool. Furthermore, it is sometimes difficult for students with
defects of vision to receive the third dimensional impression. This
is an unusual situation, but in some instances the use of the stereoscope
will aid in detecting defects of vision.
