    - Microscopy is the method of studying micro-structure constituents such as grains, phases, non metallic inclusions, etc.

    - Bright and dark field illumination are the different parameters in microscopy.

    - Bright field illumination parameter is used for producing images with dark non-flat structure and bright back ground. These include pores, edges, etched grain boundaries.

    - Dark field illumination parameter is used for producing images with bright non-flat structure and dark back ground.
