Information: - Robert Capa (born Endre Friedmann; October 22, 1913 May 25, 1954) was a Hungarian war photographer and photo journalist, arguably the greatest combat and adventure photographer in history. - A documentary film is a nonfictional motion picture intended to some aspect of reality, primarily for the purposes of instruction, education, or maintaining a historical record. Such films were originally shot on film stockthe only medium availablebut now include video and digital productions that can be either direct-to-video, made into a TV show, or released for screening in cinemas. "Documentary" has been described as a "filmmaking practice, a cinematic tradition, and mode of audience reception" that is continually evolving and is without clear boundaries. - A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic medium such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating photographs is called photography. The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek ("phos"), meaning "light", and ("graphe"), meaning "drawing, writing", together meaning "drawing with light". - Direct-to-video or straight-to-video (also known as direct-to-VHS, direct-to-DVD, direct-to-Blu-ray, direct-to-digital, etc.) refers to the release of a film to the public immediately on home video formats rather than a theatrical release or television broadcast. Because inferior sequels or prequels of larger-budget films may be released direct to video, references to direct-to-video releases are often pejorative. Direct-to-video release has also become profitable for independent filmmakers and smaller companies. - The Falling Soldier (full title: Loyalist Militiaman at the Moment of Death, Cerro Muriano, September 5, 1936) is a photograph by Robert Capa, claimed to have been taken on September 5, 1936. It was said to depict the death of a Republican, specifically an Iberian Federation of Libertarian Youth (FIJL) soldier, during the Spanish Civil War. The soldier in the photograph was later claimed to be the anarchist militiaman Federico Borrell Garcia. - Film stock is an analog medium that is used for recording motion pictures or animation. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to X-rays and high-energy particles. Most are at least slightly sensitive to invisible ultraviolet (UV) light. Some special-purpose films are sensitive into the infrared (IR) region of the spectrum. - Federico Borrell Garcia (January 3, 1912 September 5, 1936) was a Spanish Republican and anarchist militiaman during the Spanish Civil War, commonly thought to be the subject in the famous Robert Capa photo "The Falling Soldier" (Loyalist Militiaman at the Moment of Death, Cerro Muriano, September 5, 1936). - The Spanish Civil War, widely known in Spain simply as The Civil War or The War, took place from 1936 to 1939 and was fought between the Republicans, who were loyal to the democratic, left-leaning and a relatively urban Second Spanish Republic in an alliance of convenience with the Anarchists, versus the Nationalists, a falangist, Carlist and a largely aristocratic conservative group led by General Francisco Franco. Although the war is often portrayed as a struggle between democracy and fascism, some historians consider it more accurately described as a struggle between leftist revolution and rightist counterrevolution. Ultimately, the Nationalists won, and Franco then ruled Spain for the next 36 years, from April 1939 until his death in November 1975. - La sombra del iceberg ( Spanish for '' The shadow of the iceberg '' ) is a 2007 documentary film , that claims the photograph The Falling Soldier by Robert Capa was staged , and that Federico Borrell Garcia was not the individual in the picture . The documentary makes several claims : A 1937 Spanish anarchist publication claimed that Federico Borrell died behind a tree . A specialist in forensic science claimed after analyzing pictures of Borrell and pictures of the militiaman that the militiaman depicted is not Federico Borrell Garcia . In 1975 a journalist named Gallaher said that Capa told him that the picture was staged . An astronomical study concludes that the picture was taken at 9:00 a.m. , not at 17:00 . No battle happened at 9:00 . After reading the paragraphs above, we are interested in knowing the entity with which 'la sombra del iceberg' exhibits the relationship of 'main subject'. Find the answer from the choices below. Choices: - death - education - fascism - film - history - journalist - photography - reality - spanish civil war - vhs - war - writing
A:
spanish civil war
