Photomicrographs (ASTM E883) are incorporated in reports showing the structure of metals, unetched or etched with a variety of different etchants, using the microscope's camera.
The left photo represents an inclusion in a high manganese casting. The right photo shows deformation bands.
These are typical structures.
Photomacrographs are routinely taken depicting the specimen's condition for macro-cleanliness or grain flow of forgings. Photos are also taken of the specimen in the as received condition for failure analysis.
