Living leaves
Look for leaf close - ups on trees , shrubs or flowers . For tree leaves I use a medium long focus lens with some extension , or a long - focus macro lens so as to give me a reasonable working distance and still retain a close - up image . I am always on the look - out for an iso lated leafy branch lit from behind by the sun Venation patterns , as well as the structure of hairy and spiny leaves , are also best shown by back lighting - sun or flash . New spring leaves have a distinct color , which lasts for a few brief weeks ; while the leaves of many tropical rain forest trees open as a rich red color . Skylight reflections on shiny leaves can be removed by diffusing the natural light through a sheet of cheesecloth ( see p . 152 ) or by using a polarizing filter on the camera . Such a filter may also be useful for darkening surface water and increas ing the contrast between the floating leaves of water lilies . Many pot plants have striking leaves and , if the plants are positioned near a window , they can be lit by natural light , though flash or fiber optics will provide far more scope for creatively lighting portions of the leaves .
Venation pattern
I took this detail of the underside of a Caladium leaf inside a greenhouse in Singapore's botanic gardens . Since the available light level was low , I had to use a tripod and 1 sec exposure to stop down the lens . I was therefore able to get both the pattern of the raised red veins and the leaf blade sharply defined . Lens 55mm micro - Nikkor Mag , on film × 0.5 Mag , on page × 3
Intensifying the color
To photograph this black gum in the fall , I searched for a camera position where I could use the sun from behind to enhance the rich golden color . I found this picture by walking beneath the overhanging branches and looking skywards . Where the leaves overlap one another the golden glow of each leaf combines to make a deep brown color and the solid twig appears as a silhouette . Lens Hasselblad 150mm + 32mm extension tube Mag . on film × 0.3 Mag . on page × 0.6
A Cross lighting for modeling
This silversword grows only on the cinder slopes of Maui in the Hawaiian islands . The early morning side lighting helped to model the rosette of the spiraling leaves . Lens 105mm micro - Nikkor Mag , on film x0.1 Mag , on page × 0.2
Back lighting to reveal structure Transillumination by direct sunlight has highlighted the parallel veins on this cabbage palm leaf . Cropping tightly focuses attention on the concertina folding . Lens 105mm micro - Nikkor Mag , on film x0.1 Mag . on page x03
