Multiple printing
Double or multiple printing is the combination of images from two or more negatives on one piece of printing paper . One of the best expo nents of this method is Jerry Uelsmann , who uses two or even three enlargers at the same time to build his intricate images , fitting all the separate parts together like a jigsaw puzzle .
If you have more than one enlarger , you simply move your masking frame from one enlarger to the next for each successive expo sure . However , you can make double or multiple prints quite successfully with only one enlarger . First , make a sketch of the complete image project each negative on a piece of tracing paper exactly the same size as the final print , and draw in the main outlines of each element . Next , make test strips of each compo nent negative , so that you can match all the exposures for density . Then print one compo nent after the other , exposing only a selected part of the paper each time , and shading the remaining portion . To avoid harsh outlines between elements you must use dodgers ( see p . 160 ) . And to prevent accidental fogging of the paper , you should always use your red filter between exposures .
You can apply multiple printing techniques to portraiture very effectively . After all , the main aim of a portrait is to make an accurate representation in pictorial form of the sitter . Consequently , the more characterization as well as information about the sitter that the portrait provides , the more successful it is . The multiple print of the artist Francis Bacon on p . 118 illustrates one interpretive application of this method .
Making a join I photographed the artist Allen Jones against an entirely white background , so that joining his top half to a copy of a pair of legs from one of his works was quite easy . First I printed the top , screening the rest of the paper with cardboard held a few inches above the masking frame to soften the join . I removed the printing paper and placed a tracing of the top image over the masking frame , see diagram below . Next , I inserted the second negative in the holder , and adjusted the enlarger height until the width of the legs and waist matched . I replaced the partly - exposed paper in the masking frame , and made the second exposure .
Joining two images D This kind of double print is quite simple because the join between the two negatives will not be very obvious . Choose two negatives with similar tones either dark or light . Hasselblad 500C , 80 mm , 1/60 sec at f11 , FP4 ( both pictures ) .
Simple double printing A This boy was photographed several times in different positions , but always against the same white background and at the same distance from the camera . This makes double printing very easy - you simply trace the position of each figure and then expose one while screening the space left for the other two , see diagram left . The uniform white background ensures that no join shows between the figures . Nikkormat FT , 50 mm , 1/125 sec at f8 , FP4 .
