A scleroscope is a device used to measure rebound hardness. It consists of a steel ball dropped from a fixed height. The device was invented in 1907. As an improvement on this rough method, the Leeb Rebound Hardness Test, invented in the 1970s, uses the ratio of impact and rebound velocities (as measured by a magnetic inducer) to determine hardness

AP 3-D Art and Design is a three-dimensional (3-D) art course that holds many similarities to the 2-D course. The course deals with 3-D artistic applications such as metalworking, sculpture, computer models, and ceramics. Like AP Studio Art 2D, the focus is on the design of the artwork itself as opposed to its composition.
AP Art History is designed to allow students to examine major forms of artistic expression relevant to a variety of cultures evident in a wide variety of periods from the present to the past. Students acquire an ability to examine works of art critically, with intelligence and sensitivity, and to articulate their thoughts and experiences.
Although art institutions in the United States no longer conceptualize snapshots as found photography (i.e., as found photos in the technical sense), collectors of snapshots still do. The collecting community around New York’s Chelsea Flea Market has been documented in a film, Other People's Pictures, by Lorca Shepperd and Cabot Philbrick.
Screen theory is a Marxist–psychoanalytic film theory associated with the British journal Screen in the early 1970s. [1] It considers filmic images as signifiers that do not only encode meanings but also mirrors in which viewers accede to subjectivity. [2]
The matte can serve as a binary mask, defining which of the image parts are visible. In a more complicated case it enables smooth blending of the images, the alpha matte is used as the transparency map of the top image. Film production has known alpha matting since the very creation of filmmaking. The mattes were drawn by hand.
The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. [1] Adams described the Zone System as "[...] not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40."
