Excerpt from An Experimental Study of the Lippmann Color Photograph: A DissertationWhen so mounted the pictures are ready for observation. It is of extreme importance that they be observed by parallel light and shielded from all side light. The best conditions are given by a small opening in a wall facing a brilliant white sky. If the observer stands with his back to the opening and holds the picture at arm's length re¿ecting the sky it appears at its best.These precautions are most necessary in the case of pictures of natural objects, for reasons which will appear later. Spectra and similar subjects, where the re¿ecting laminae are numerous and deep in the film, are visible much more easily, but are of course best seen under the conditions given above.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
