The White House is the official residence and principal workplace of the President of the United States, located at 1600 Pennsylvania Avenue NW in Washington, D.C. It has been the residence of every U.S. president since John Adams in 1800, and the term is often used by journalists as a metonym to refer to the acts of the President and his top advisors.
The house was designed by Irish-born James Hoban and built between 1792 and 1800 of white-painted Aquia Creek sandstone in the Neoclassical style. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) expanded the building outward, creating two colonnades that were meant to conceal stables and storage.
Black-and-white, often abbreviated B/W or B&W, is a term referring to a number of monochrome forms in visual arts.
Black-and-white images are not usually starkly contrasted black and white. They combine black and white in a continuum producing a range of shades of gray. Further, many prints, especially those produced earlier in the development of photography, were in sepia (mainly for archival stability), which yielded richer, more subtle shading than reproductions in plain black-and-white. Color photography provides a much greater range of shade, but part of the appeal of black and white photography is its more subdued monochromatic character.
