| Description |
Afocal photography, sometimes called digiscoping, simply means that a camera with a taking lens is used where an observer's eye would normally be, looking into the microscope (or telescope) through the eyepiece or ocular. Execution, however, is not especially simple if the photographer wants to collect multiple images so that focus-stacking software can be used to increase the depth of field. The only thing that should move between exposures is the subject, and this movement is controlled by slight adjustments of the fine focus knob on the microscope. The technique shown here involves a tripod with a geared central column for smooth vertical positioning, a 3-way Manfrotto 3028 tripod head to hold the camera at the same angle as the microscope viewing tube, a Velbon Macro Slider for fine control of on-axis and lateral movement of the camera, and a taking lens with a focal length chosen to minimize or eliminate vignetting of the field of view. A remote shutter release is essential, and the electronic shutter of the Nikon V1 is a plus. |
