Fungal forms
Fungi exist in many forms : as toadstools on the ground ; as shelf - like brackets on trees ; and as molds on food . Except for perennial woody brackets , most fungi are short - lived , so never postpone photographing a perfect specimen . Old woodlands , where there are plenty of rotting tree trunks , are rich sites for fungi especially when a rainy spell coincides with warm weather in the fall .
If you use available light outside make sure that it is not filtering down through colored leaves . When available light is poor , you may have to double rate the film speed to get a better depth of field . An aluminum foil reflector ( see p . 152 ) will also help to boost low light levels and I have even used a small hand mirror for spotlighting tiny specimens in the shade . In dark situations you will have to use flash . Try to avoid using direct flash on pastel - colored fungi ; bounce it off a white board , or diffuse it with cheesecloth .
If fungi are collected for indoor photography , and have to be kept overnight , put them inside a sealed box in a refrigerator ; in a centrally - heated room they will soon de hydrate and shrivel .
A moldy close - up
This is a close - up of the black spore sacs on the orange skin of a rotting carrot . A pair of flash heads gave me enough light so that the lens could be well stopped down for this magnified image . Lens 55mm micro - Nikkor + PB4 bellows Mag . on film × 2.5 Mag . on page × 12
Flush with the wall
Inside a derelict house l found this dry rot fungus growing on the wall . The bracket changes color with age . The advancing outer edge is white , while the rust - colored spores are shed through the pores . Even though I was able to get the camera set up so that the film plane was parallel with the wall , only a small amount of window light reached the fungus , so I used a tripod for the sec exposure . Lens 105mm micro - Nikkor Mag . on film × 0.1 Mag . on page × 0.4
Boosting ambient light
I wanted to get in close to this parasitic bracket fungus to show the liquid secretion from the pores , but the fungus was over shadowed by the leafy branches of the oak tree on which it was growing . I therefore used an aluminum foil reflector sheet to boost the available light , thereby highlighting the pores . Lens 55mm micro - Nikkor Mag . on film × 0.1 Mag . on page × 0.5
