Variations on a theme
Perhaps the most obvious way of producing a thematic series of photographs is to take a single subject and to explore it in depth . Most simply a subject can be photographed at different magnifications , from different view points , or , as is so often illustrated in photo graphic books , by varying the direction and type of lighting . More imaginatively , pictures may be seen as abstractions rather than replications of reality ( see p . 90 ) . I took my variations of the skin - print theme directly with the camera ; other variations could have been produced by darkroom techniques ( see p . 138 ) .
An everyday subject such as water offers endless possibilities for photography - in both monochrome and color . In this book there are several graphic examples of different ap proaches which can be used to photograph such a basic liquid . Moving water can be por trayed either by using a slow shutter speed or a high - speed flash . Water droplets can be high lighted with strong side lighting or portrayed as simple lenses ( see p . 15 ) .
An alternative approach is to look for totally unrelated subjects which can be grouped because of their shape , color or texture .
Revealing the invisible V I dusted my fingertips with fluorescent powder so they glowed under ultra - violet light ( see p . 56 ) . Lens Hasselblad 80mm + 16mm extension Mag on film x0.15 Mag . on page × 0.4
Fixing a footprint ▷ This print of my son's foot was made without a camera . After stepping on a sponge soaked in hypo clearing agent , he pressed the foot onto unexposed print paper which I then exposed under the enlarger and developed . Mag . on print and on page × 1
A fingerprint
This fingerprint was made on white paper by first pressing the finger onto a polished metal block covered with a thin layer of black printer's ink . I photographed it by indirect light using a light cone . Lens Hasselblad 80mm + 91 mm ( 55 + 36 ) extension Mag . on film x1.5 Mag . on page × 5
An impression ▷ I made this impression of my husband's big toe by using a liquid silicone rubber , known as Silfo dental plastic , mixed with a few drops of catalyst . My husband pressed his toe into the mixture , which was on a piece of glass . for four minutes . I then transferred the glass , with the plastic impression , onto a photo jack ( see p . 152 ) so l could bring it into focus beneath an overhead camera . I lit the impression with a fiber optic so that the ridges and the pores can clearly be seen . Lens Leitz Photar 25mm Mag . on film × 4 Mag . on page × 16
