Set Up

Here's an image of the basic set up

The camera was placed on a copystand. Attached are bellows and a 38 mm thimble lens. The lighting was provided by an external microscope light placed on or next to the sample at about a 45* angle. The camera used was an Olympus E-1 DSLR.

Since a lens with a focal length of 38 mm was used, the working distance (the distance between the object and the lens) was 38 mm. The bellows were extended to create an image at capture 4x magnified. Using the equation v = (m + 1) f , (see expanded definition), the bellows are 185 mm long. The light was stopped down to a small aperture in order to provide light that was more contrasty.
