DRYING THE FILMS Much time is wasted while waiting for films to dry,especially in warm weather and when the atmosphere 9 V o v a i i is humid. The general habit has been to develop thefilms and hang them up to dry during the night. Un-less the room is well ventilated even this length of timeis sometimes insufficient. A drying box can easily be made which will dry filmsin from twenty to thirty Drying Cupboard for Films An ordinary cupboard will suffice, providing the dooris cut down so that there is a space of eighteen inchesboth top and bottom. An electric fan placed horizontally at the bottom willdrive air through the cupboard and thus dry both sidesof the film simultaneously. Wooden rods, in whichpointed pins are driven, are placed in the position 10 T^ovtvaiij usually occupied by shelves, and the film with weightedclip attached to one end, is spiked on the pins. It is not necessary to run the fan at its utmost speedand the weight of the metal clips will be sufficient tokeep the films from flapping against one another. The higher rods are for the twelve-exposure rollsand the lower rods for six-exposure rolls. The filmsattached to the lower rods will dry more quickly thanthe others but the printing-room will be fed systemat-ically by the drying cupboard. A quicker method of drying is to draw hot air throughthe drying chamber by means of a fan, but the apparatu
