60 IV. MAKING 16-MM OEIGINALS
Single system recording is rarely used for professional 16-mm production because :
(a) It is rarely necessary or even desirable to record the sound which actually forms part of the action being photographed. This is especially true of 16-mm nonentertainment films.
(ft) It is impracticable to edit single system film in a satisfactory manner.
(c) Sound quality is decidedly inferior because the resolving power of picture original film is usually much lower than that of film designed especially for sound recording.
In the double system method, the sound is recorded on a separate film, and usually not at the time at which the picture is taken. The double system method permits the use of the best available raw films for both picture and for sound without serious sacrifice of quality for either. It is for this reason that the double system method is used almost exclusively for all theatrical 35-mm films as well as for commercial 16-mm films.
Combinations of both the single and double system methods are occasionally used. These combinations are intended for special purposes and account for an insignificant fraction of all film consumed.
The 16-Mm Picture Original Film for the 16-Mm Picture Original
While 16-mm film has much in common with 35-mm theatrical film, there are certain features which have no counterpart in the larger size. The 16-mm picture original is an excellent example.
When a 35-mm black-and-white positive is desired, it can be obtained from a 35-mm original only by printing from a negative, since there is no 35-mm reversal film commercially available. In 16-mm, however, direct positives such as black-and-white reversal and color reversal are the rule rather than the exception. The attempt to use the terms original and negative interchangeably in the 16-mm medium is not only confusing but definitely in error although the terms are quite correct in 35-mm where they are customarily so used.
While the apparently obvious means of obtaining a 16-mm black-andwhite print would seem to be the printing of a 16-mm negative, this method is usually the least satisfactory when good quality prints are required from assembled (edited) originals. The dirt and scratches accumulated in even meticulous handling of 16-mm original film are quite objectionable when negative is used. In addition, annoying light flashes appear in the print wherever a splice occurs in the negative.
