MONTHLY CHAT
ACONTEMPOKAKV ih. IJritM. Journal of Photography, points to increasing candor in the publication by scientists, engineers, inventors, etc., of I heir discoveries, with less and less secrecy in evidence. It also mentions, however, that all scientific research is not published, with the "mistakes" made more often than not being withheld from the light of the printed word.
The argument is given that immeasurable time could be saved if the mistakes as well as the successes reached the printed page so that others would not go over ground that has proved fruitless with the concomitant of "terrible waste of time, money and materials."
In our field the Society of Motion Picture Engineers, as well as others, have led the way in this type of candor, and it is to be expected that in time greater realization will be held by the organized groups as well as individuals that all will be served better if mistakes are brought to light. With television looming as the next great project, LP. believes it will be well for all researchers to effectively tell of their mistakes as well as their successes to the end that time, effort and materials will be saved to the greatest possible extent. Infinitely more will be accomplished in the final analysis through such a sensible procedure.
During the third quarter the allotments of 35-mm motion picture film for the production of entertainment pictures will total 271,000,000 linear feet, and the allotment for newsreels is 56,860,219 linear feet. According to the War Production Board the amount of 35-mm film to be made available for entertainment pictures in the third quarter will be an increase of 10.000.000 linear feet over the second quarter, and 15.000.000 feet over the third quarter total. The newsreel film uppage is 4,000.000 feet over both the first and second quarters.
Some of those in the industry may believe the increases indicate a big opening up in the supply situation, and less need for film conservation. This is far from true, and it is just as essential now that projectionists observe maximum conservation efforts in the future as they have in the past. Much film has been saved by the thousands of conscientious projectionists who realize the war must be fought on the home front just as well as in the combat areas. The real patriot will do as much as possible to keep the show going with a minimum of waste until the last Jap hollers the Oriental equivalent of "uncle." That happy day for us, according to military experts, is far in the future.
