Description:
Founded in 1915 by a Chicago printing company as a regional trade paper for Midwest exhibitors. In 1916, editor Martin Quigley bought out the owners, and over the next 15 years, he grew EXHIBITORS HERALD into one of the most important national, weekly trade papers in the film business. Quigley acquired MOTOGRAPHY in 1917 and MOVING PICTURE WORLD in 1927. In 1930, he acquired MOTION PICTURE NEWS and the new 'consolidated' publication became MOTION PICTURE HERALD. From the pulpit of his editorial page, Quigley preached the need to improve the motion picture industry and improve the quality of the films. He skillfully served as a mediator in disputes -- between distributors and exhibitors, between the film industry and the Catholic Church (Quigley was one of the architects of the Production Code). Quigley claimed that EXHIBITORS HERALD represented the 'independent exhibitor' and sections like 'What the Picture Did for Me?' certainly provided a forum for theater owners. But plenty of exhibitors viewed Quigley as a servant to the studios and large theater chains. In response, publications such as SHOWMEN'S TRADE REVIEW, INDEPENDENT EXHIBITORS FILM BULLETIN, HARRISON'S REPORTS, and BOX OFFICE were either formed or grew significantly in the years following Quigley's brief moment of consolidation in 1930. -- Eric Hoyt, 2014

IMi Y BONDS! low relative aperture in a much longer interval of time, thus a lens of high relative aperture permitted a fast exposure and was referred to as a fast lens. As the letter "f" is the standard symbol for relative aperture, the term "f-speed" is another correct meaning for the relationship between the focus of a lens and its smallest opening. The letter "f" is the designation for the figure obtained when the focus of a lens is divided by the diameter of the smallest opening in that lens. In order to understand this relationship, let's compare a big water-carrying pipe with a fast lens, and a smaller pipe with a slow lens. If water flows through both pipes, the larger one will allow more water to pass through it in the same time interval than the smaller one because of its greater area. As the big pipe will conduct a given amount of water in a shorter period of time, it is faster than the smaller pipe. The accompanying drawing illustrates this principle by comparing pipes and lens of equal diameter to show how the area influences their transmission capacity. Let us assume that pipe A is 2-3/64 inches in diameter, while pipe B is only 1-29/64 inches in diameter. Pipe A will fill a 15-pint container in the same time that pipe B will fill a 7^2-pint container. In the same drawing, lens A has a diameter of 2-3/64 inches, and lens B has a diameter of only 1-29/64 inches. If a light source is focused through lens A and produces an average illumination of 15 foot-candles on a screen of given size, lens B will produce only 7 3/2 foot-candles (provided all other conditions are equal). It is easy to see, therefore, that the volume of water which will flow through any two given pipes, or the volume of light which will be transmitted by any two given lenses, is proportionate to the areas of their smallest openings — if all other conditions are equal. In the pipes and lenses shown in the drawing pipe A has twice the area of pipe B, and similarly lens A has twice the area of lens B. In answer to your second question, I have made up the following simple table showing the progressive changes at various relative aperture in the percentage of light transmitted, the average screen illumination, and the size of the smallest opening in a 4^2-inch E.F. lens. This table is based around your figures of 15 footcandles average illumination for a 454inch E.F. at f:2.2 on a screen of known size. Per Cent Average Relative Dia. Smallest Transmission Ft.
