Film "K" is converted from rolls of Kodak Plus-X Aerographic Film 2402, expired since 2000. These perforated rolls of 5 inches’ width were cut in 4x5, 5x7 sheet film to be used in regular large format cameras. The rolls are now also cut in 120 roll film format for use in medium format cameras. Despite its long expiration date, this 3-kilometre stock of aerial film, has been stored in good condition and still gives very good results. A nostalgic film, as the emulsion has been discounted by Kodak a long time ago. As this original stock of film is perforated, the perforation could be slightly visible on two side of the pictures, as shown on the sample image.
