Introduction
Close - up photographs - especially when taken at magnifications larger than life - size - can make the most ordinary subjects extra ordinary . Moving in close with the camera pro duces images that automatically concentrate the viewer's attention , either on minute sub jects or on a small part of a larger , more familiar object , to reveal detail that can be easily overlooked by the casual observer . Even conventional photographic techniques can re veal features and details which are not dis cernible to the naked eye . More specialized techniques involving stroboscopic flash , ultra violet light and infra - red film open up new worlds , worlds normally unseen because the events in them occur too rapidly for our eyes to grasp them or because the images are formed in wavelengths outside the visible spectrum . My definition of a close - up photo graph is given on page 18 , and throughout this book I have used this word in preference to macrophotography , which is often erroneously used as a synonym .
Close - up pictures are now widely used by teachers to educate , by advertisers to tempt , and by artists and designers as sources of in spiration . Biologists , geologists , doctors and dentists are among the many research workers
Color harmony These hand - thrown flower pots were stacked outside a local pottery ready for dispatch . A recent rain shower had enriched the color of all the pots , but I was particularly attracted to this group which were enhanced by clumps of green clover leaves . My assistant held a silver reflector so that additional light was thrown into the dark center of each pot . Lens Hasselblad 80mm + 10mm extension Mag . on film × 0.1 Mag . on page × 0.35
Dripping water ▷ I took this detail of a rock in Zion Canyon , Utah , with a long - focus macro lens . It is known as Weeping Rock , because water perpetually drips off it . This phenomenon arises from the porous nature of Navajo sandstone which readily absorbs water . As water permeates through the sandstone , it is forced out horizontally along a spring line wherever it hits an 163 € impervious layer of shale . I used a 1 sec exposure to record the water as continuous lines . highlighted by the direct sunlight . Lens 200mm micro - Nikkor Mag , on film × 0.08 Mag , on page × 0.45
