acteristics are the same as those of the familiar Superpan, though its speed is slightly less — Weston 24 to daylight, 16 to Mazda.
This film can be valuable in several ways. Since it gives a positive transparency rather than a negative, it can be a means of simplifying things for those who, for business or pleasure, make use of projected film-slides or transparencies. With this film, such slides can be made directly, rather than going to the intervening trouble and expense of making a negative and then having transparencies printed therefrom.
But this film has also a further application. Like mose reversal emulsions, Agfa Reversible Superpan has unusual fine-grain characteristics. It is therefore an excellent material for making pictures from which extremely large prints are to be demanded. This film cannot, of course, be developed as a negative, but it can be reversed in the usual way, and then used for the making of an enlarged negative of any size, from which either contact prints or further enlargements can be made.
This, incidentally, offers great possibilities to those who use the advantages of the miniature-camera for portrait or commercial photography. Such work often requires retouching or other alteration of the negative, which is difficult, if not impossible with ordinary minnicam negatives. Using Agfa Reversible Superpan for the original picture and making an enlarged negative, such retouching becomes wholly practical.
Thus it will be seen that each of Agfa's six miniature-camera films fits neatly into some definite purpose of the minnicamerist's work. To sum things up briefly, it will be seen that there are three general-purpose films, and three special-purpose films, each of which has its special utility.
Agfa Supreme is the unexcelled all-around film for snapshotting landscapes, speed pictures, portraits, candid camerawork, and nearly every phase of amateur and professional minnicam work.
Agfa Finopan is a fine all-around film especially suited to pictures and individuals where extreme fine-grain quality is paramount.
Agfa Plenachrome is an economical outdoor film, especially useful where it is desired to differentiate strongly between oranges and red.
Agfa Ultra Speed Pan is the unique film for any purpose which calls for unsurpassed speed — for working under unfavorable illumination, for speed work, and the like.
Agfa Infra Red was specifically created for making night-effects by daylight, for intentionally overcorrected filter shots to obtain dramatic effects, and for penetrating haze in distant landscapes.
Agfa Reversible Superpan is specially suited to making direct transparencies, and to making pictures for extreme enlargement by means of enlarged negatives, or where minnicam pictures must be retouched or modified.
It is hoped that this discussion of Agfa's six miniature-camera films will help those who use them to answer the often perplexing question of which film to choose for a given picture.
