In making night-effects with this film, professional cinematographers have learned several things. For one, the most convincing effects are secured by composing the picture so that a rather heavy shadow cuts across the foreground. For another, while clouds ordinarily add to the pictorial value of a scene, they do not add to the convincingness of a filtered night-effect. Such scenes depend greatly upon a jet-black sky, which suggests night. Thus the best night-effects are those which include a cloudless sky. Similarly, if film and filter are to darken the sky, the camera should not be pointed closer to the sun than a 90 degree angle; the best results come shooting directly away from that part of the sky in which the sun is. Lighter filters and fuller exposures, incidentally, give a lighter sky, which suggests the luminous quality of a twilight sky.
In Emergencies Infra-Red Can Be Used Without A Filter, As This Picture By Dr.

It is peculiarly interesting that Agfa Infra-red film need not be restricted in use to the special types of work described above. Many photographers have found that when occasion demands, the film can be used satisfactorily without filters, to obtain a picture similar in general appearance to that produced when a regular panchromatic film is used without filter. This procedure affords an obvious advantage when there is no opportunity or time to reload the camera with a regular panchromatic film for a few "straight" photographs. Naturally the interpretation of color values in the photograph is not then strictly accurate, because Agfa Infra-red film is relatively insensitive to green and yellow light; but for many subjects this is a minor consideration. When used without filter in this way, the film can be given about twice the exposure which would be used for Superpan Supreme.
