One disadvantage of this method is that a small quantity of illm or paper cannot be processed at a low cost, due to the fact 30 that large quantities of p solutions are ` needed to till the large tanks. Another disad vantage is the need for a' leader to keep the machine threaded and still others are the large space occupied by the machine and its cost of 35 construction. _ ' » The third method of photographic pr is the using. ot some form of holder that carries a quantity of illm or paper in a compact form-in which it may be placed in the various 40 liquidst ' _ Asiswellknowmmotionpictureñlmmaybe _ _ 2Q Eì‘ig. 1 is a sectional elevation of the assembled apparatus showing a spiral holder with pape passes over a series of guide rollers, immersing 25 10 terial being processed thus keeping them free. through the various steps, including developing, ' ` The method of this invention includes circu lating the liquids between the portions of ma First, that of processing the prints individually, l mounted therein. » Y .
