Our
passion is photographing the fossil world. Magnification permits
us to capture exciting new and unexpected images as colorful minerals
and artful patterns become apparent. However, making small things
larger creates problems: it accentuates vibrations that cause image
blurring, depth of field becomes less, color saturation diminishes,
and dust becomes visible. You might think these problems would require
a change in camera and film, but that is not true.
Camera, Lenses and Keeping it Steady
We have used large, medium and 35mm format cameras, and find little
difference in the end product. The larger film size allows you to
capture images with more photosensitive grains; thus larger prints
usually can be made. For most of our work, however, we use normal
lenses with either bellows or extension tubes. Working with bellows
is more convenient because magnification and field can be varied
easily. Adding additional extension tubes to the bellows doesn’t
help; while further magnification can be achieved, vignetting occurs.
Often, we get by with a quarter-inch ring on our Hasselblad, if
we use a 16-exposure film back that hides darkened corners.
