@misc{65592, note = {{Description Rand: "Lantern Slide Projector with Tachistoscopc shutter" does not seem to be correct: No shutter identifiable. Possibly M97: "Magic lantern. Stereopticon screens. By Elbs, Freiburg. \$20". Comment II Rand Evans: The attachment on the front of the magic lantern is Muensterberg’s color mixer made from a set of colored gels. Munsterberg Nr. 77[77. Apparatus for mixing colors by the combination of colored gelatine papers. After Münsterberg, by Elbs, Freiburg. \$20.] The gels were slipped into place like lenses, being mounted on levers. This device seems to be in use in one of the other photos in Muensterberg’s article (kk: link to image in PDF). I will look for some reference to this device in Muensterberg’s publications. http://vlp.mpiwg-berlin.mpg.de/library/data/lit814 0/index\_html?pn=14\&ws=3\&mk=0.0638/0.6652\&wid=digi\_ 5885 http://vlp.mpiwg-berlin.mpg.de/library/data/l it8140/index\_html?pn=11\&ws=1.5\&mk=0.5507/0.6182\&wi d=digi\_8266 See also (definition of stereopticon): http://www.reference.com/search?q=stereopticon For the front part (?)of the device, see img30218}}, url = {https://vlp-new.ur.de/images/img30054} }
