Coprinus quadrifidus

Photograph taken with a Nikon 995, June 2002.

In our area C. quadrifidus grows on well-rotted wood (stumps, logs) and fruits in large clusters in early summer.  We have had a wet spring in Guelph which was conducive to this cluster fruiting in mid June.

In this shot the camera was set to 'Aperture Priority' and the aperture was set to f10 which is the smallest aperture (largest f stop).    In the darkness of the woods this requires a long exposure so it is necessary to use a ground tripod.  Originally one of my reasons for buying the Nikon 995 was that it had shutter speeds up to eight seconds (important for macro photography).  I never thought to check on the minimum aperture for maximum depth of focus!     Normally with  my SLR Nikon I set the aperture to f16, f22 and rarely f32.  If light is bad I go to f11 or even f8.   So a minimum aperture of f10 is a limitation I don't really like. However,  these 'digital' lenses are not the same as lenses for 35 mm cameras, they have a much shorter focal length and may have a much larger depth of field at  the same nominal aperture.
