On the picture a bit cartoonized Agu - my close friend.
Task for school and my first etching. It's original print - with small touch of Photoshop. ;]
Etching is the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio in the metal (the original process—in modern manufacturing other chemicals may be used on other types of material). As an intaglio method of printmaking it is, along with engraving, the most important technique for old master prints, and remains widely used today. More info here: [link]
