5.
heavy cloud effects In night shots as they tend to destroy the illusion of a night sky.
Remember that night effects imitating moonlight illumination inspire the impression of coldness and correspondingly more contrast than night effects with artificial light sources such as street lamps, illuminated windows, etc.
6. In some scenes it is of advantage to show detail in the background which would be nearly impossible to obtain when actually photographing at night and to which, therefore, the medium of Infra-Red negative is of particular advantage. In other scenes it will be desirable to subdue background and this automatically requires raising the light level of the foreground, thus permitting a sufficient difference in contrast between background and foreground to enable the emphasis on foreground detail in the print.
7. To avoid overcorrection of the lips when photographing closeups on Infra-Red, a special lip rouge should be applied, which is obtainable at Westmore's Beauty Salon. Other changes in make-up are not required.
8. Using Infra-Red negative for night effects in scenes with large areas of fresh green foliage, one will find that in some instances the effect of overcorrection of green will emphasize the reality of moonlight effects, while in some instances the same overcorrection might tend to create an impression of unnaturalness.
9. Using diffusion for night shots on Infra-Red is permissible for all large closeups. Remember, however, that exaggeration of this effect is definitely detrimental, particularly when lower contrast filters are used and the light conditions lack brilliance.
10. Agfa Infra-Red Type B is developed and processed exactly like panchromatic negative.
Further practical experience in the use of Infra-Red negative for night photography in the daytime will, no doubt, reveal additional valuable information which will be helpful in establishing a definite technique of photographic procedure. The fact that this type of effect-photography is based solely on color correction alone demands a thorough study of the response of this specially sensitized film to objects, light sources and material of different colors and of different Infra-Red reflection and absorption characteristics.
Notwithstanding the excellent reception accorded Agfa Infra-Red Type B by the motion picture industry, a word of caution seems to be timely in order that the impossible be not expected. At the same time, producers, directors, and cameramen should be encouraged to exercise patience in the investigation of the full possibilities this film material offers when technical application is correct. The practical use of this new medium, which was produced as the result of suggestions by prominent studio technicians, undoubtedly has already assisted the industry to more realistic reproductions. Additional study and practical experience will, no doubt, further increase its utilization.
