アクション・ペインティング
Although Abstract expressionism spread quickly throughout the United States, the major centers of this style were New York City and California, especially in the New York School, and the San Francisco Bay area. Abstract expressionist paintings share certain characteristics, including the use of large canvases, an "all-over" approach, in which the whole canvas is treated with equal importance (as opposed to the center being of more interest than the edges). The canvas as the "arena" became a credo of Action painting, while the "integrity of the picture plane" became a credo of the Color Field painters. Many other artists began exhibiting their abstract expressionist related paintings during the 1950s including Alfred Leslie, Sam Francis, Joan Mitchell, Helen Frankenthaler, Cy Twombly, Milton Resnick, Michael Goldberg, Norman Bluhm, Ray Parker, Nicolas Carone, Grace Hartigan, Friedel Dzubas, and Robert Goodnough among others.
