This is a time exposure taken through a student model stereo microscope. I used a Nikon Coolpix 5400 camera with a special adjustable adapter that enables one to remove the microscope eyepiece and make the camera confocal with the scope. (The black area at the lower left is a telltale sign of vignetting.) I used a photoflood light to add extra illumination from the side, let the camera customize the white balance, then cropped and enlarged the resulting image. Were I to retake the shot today, I would use a digital SLR (which I didn’t have at that time)and a fiber optics illuminator. Either way, one sets the camera to the widest possible aperture and zooms in as necessary to minimize vignetting.
