It's easy to make stereograms with a regular microscope using a dual-color filter. But until now, ironically, I could not do the same for my stereomicroscope. The problem was the microscope had top lighting. It is possible to attach a filter to the lamp, but surrounding light could spoil the image. So instead I took advantage of the fact that each eyepiece in the 'scope presents a different view. I took two pictures with the microscope, each through a different eyepiece. Then I put the two images together on the computer, leaving a small space between them. To view the 3-D picture, stare at the image and diverge your eyes by letting them unfocus. Cactus spines.
