Regardless of the medium, subject, or who the artist may be, each form of art conveys some sort of emotion. While describing different lines, author Mary Stewart points out in Launching the Imagination, "The network of agitated lines Giacometti used in figure 1.3 suggests anxiety, while the fluid lines in figure 1.4 express movement and playful energy" (3). Another example of emotion through art using a different medium is value distribution. This basic element is displayed in photographs both in figures 1.69 and 1.71, which perfectly display how "Careful use of value distribution can increase emotional impact" (30, 31). The value distribution is shown in 1.71 through the use of a dark room, with a slight light illumination to the left of the photo that allows just enough light in to view the people whom are standing under a large structure, which the text points out to be a bus shelter. This value distribution helps to build mystery within the photo, which brings out strong emotion within the audience.
