- In its simplest form, photomicrography with a solar microscope works as follows: The image of an object that has been illuminated by sunlight and observed through the objective lens of a microscope is projected onto a white screen (e.g. a wall). This projected image is then recorded by a photographic device.

What is photomicrography and how does it work?

photomicrography, photography of objects under a microscope. Such opaque objects as metal and stone may be ground smooth, etched chemically to show their structure, and photographed by reflected light with a metallurgical microscope.

How is photomicrograph used?

A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times.
