2. Anton Giulio Bragaglia Fotodinamismo futurista (Futurist photodynamism). Rome, Editore Nalato, 1913. Second edition. Illustrated with 15 halftone plates of Bragaglia's photographic work. 48 pp. Through his theory of photodynamism, A.G. Bragaglia applied Futurist painting's celebration of speed and motion to the medium of photography. Fotodinamismo is significant not only for its role in providing a theoretical basis and foundation for Futurist photography, but also as the first essay on photographic theory and aesthetics of the 20th-century avant-garde. Seeking a more successful means of capturing the essence and sensation of speed and motion than chronophotography, Bragaglia advanced the theory that speed applied to actions or objects renders them immaterial and invisible- "appearance is replaced by transparency." Rather than reproducing the stiff successive moments of an action or gesture, Bragaglia's photodynamics are fluid, "visual transcriptions of energy." They present the essence of gesture and movement in a single image, and register the dynamism of speed as "vibration, sensation and emotion." The images reproduced include "The Typist," "The Slap," and other definitive, monumental photodynamics. (Hulten 435,539; Lista 1981:7-11,38-39, 1986:26; Salaris 25 )
