Given the question: Information:  - Sculpture is the branch of the visual arts that operates in three dimensions. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or molded, or cast.  - A metal (from Greek  "métallon", "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable  that is, they can be hammered or pressed permanently out of shape without breaking or cracking  as well as fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire). About 91 of the 118 elements in the periodic table are metals, the others are nonmetals or metalloids. Some elements appear in both metallic and non-metallic forms.  - Dieter Appelt ( born 1935 in Niemegk / Brandenburg ) is a photographer whose work ranges from photography , film and video to performance art that typically involves sculpture of his own construction .  - Potsdam is the capital and largest city of the German federal state of Brandenburg. It directly borders the German capital Berlin and is part of the Berlin/Brandenburg Metropolitan Region. It is situated on the River Havel, southwest of Berlin's city center.  - A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic medium such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating photographs is called photography. The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek  ("phos"), meaning "light", and  ("graphê"), meaning "drawing, writing", together meaning "drawing with light".  - A photographer (the Greek  ("phos"), meaning "light", and  ("graphê"), meaning "drawing, writing", together meaning "drawing with light") is a person who makes photographs.  - Brandenburg (Lower Sorbian: "Bramborska") is one of the sixteen federated states of Germany. It lies in the northeast of the country covering an area of 29,478 square kilometers and has 2.48 million inhabitants. The capital and largest city is Potsdam.
