Micrography (Microscopy)

Micrography (Microscopy)
An image taken from a microscope

Micrography is also the art of using microscopes to make photographs. 'Micrograph' is an image obtained by means of a microscope and contains extensive details that form the features of a microstructure. "Etching" is done to improve contrast between phases by selective attack of some phases using reagents. Micrography is a Metallurgist's forte.

Optical microscope and electron microscope are extensively used in micrography or metallography and are indispensable. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on.

Micrography as art

The microscope has been mainly used for scientific discovery. It has also been linked to the arts since its invention in the 17th century. At first scientists used the microscope to view and draw objects not visible with the unaided eye. Early adopters of the microscope, such as Robert Hooke and Antonie van Leeuwenhoek, were excellent illustrators. After the invention of photography in the 1820s the microscope was later combined with the camera to take pictures instead of relying on an artistic rendering.

Since the early 1970s individuals have been using the microscope as an artistic instrument. Web sites and traveling art exhibits such as the Nikon Small World and Olympus Bioscapes have featured a range of images for the sole purpose of artistic enjoyment. Some collaborative groups, such as the Paper Project have also incorporated microscopic imagery into tactile art pieces as well as 3D immersive rooms and dance performances.
