By ORMUND POWERS (Courtesy Orlando Sentinel) When Herbert C. McKay, F. R. P. S., arrived here a few weeks ago he rented two houses—one to live in, and one fense of his photographic laboratory. eKay is one of the leaders in the field of photographic research. He serves as consultant to manufacturers on de signing and revising equipment, and is a recognized expert in such specialized fields of photography as stere, micro and macro photo graphy, sensitometry and natural color photography. First in 1919 He first came to Eustis in 1919. He sold real estate here with Charles Giles, and began making pictures in connection with his work. In 1920 he went to Los An geles with Dr. Edgar J. Banks of Eustis to work as a cameraman for Sacred Films, Inc., which Dr. Banks directed. After six months in California, McKay returned to Eustis with Dr. Banks and made four movies here. McKay’s first book appeared in 1923. It was called, “Motion Pic ture. Photography for the Ama teur,” and was the first book to be published on the subject after the introduction of 16 mm. film. He has since written a number of other books, including, “Hand book of Motion Picture Photogra phy,” “Amateur Movie Making,” “The Cine Camera,” “Cine Titling and Editing,” “The Voice of the Films,” “Professional Motion Pic ture Photography,” “Commercial Photo Finishing,” ‘Professional Photography,” Photography for Journalists,” “Photographic Jour nalism.”’ One of the two books which he now has contracts to write will be an elementary treatise on photo graphy, and the other will be a textbook on photography for use in colleges. Soon after McKay’s first book was published he went to New York as educational director of the New York Institute of Photogra phy, the largest school of its kind. He stayed with the institute for 12 years, and in 1926 was made dean of the school. He has also served as an instructor in miniature camera, technique and natural color photography at the Brook lyn Institute of Arts and Sciences. Gone Independent Since 1936 McKay has been en gaged in independent consultation and writing. He has contributed to 30 magazines, and is the only writer whose work has appeared (Continued on Page Eight.)
