Background: Edward Henry Weston (March 24, 1886 - January 1, 1958) was a 20th-century American photographer. He has been called "one of the most innovative and influential American photographers..." and "one of the masters of 20th century photography." Over the course of his 40-year career Weston photographed an increasingly expansive set of subjects, including landscapes, still lifes, nudes, portraits, genre scenes and even whimsical parodies. It is said that he developed a "quintessentially American, and specially Californian, approach to modern photography" because of his focus on the people and places of the American West.
Context: Weston always made contact prints, meaning that the print was exactly the same size as the negative. This was essential for the platinum printing that he preferred early in his career, since at that time the platinum papers required ultra-violet light to activate. Weston did not have an artificial ultra-violet light source, so he had to place the contact print directly in sunlight in order to expose it. This limited him to printing only on sunny days.  When he wanted a print that was larger than the original negative size, he used an enlarger to create a larger inter-positive, then contact printed it to a new negative. The new larger negative was then used to make a print of that size. This process was very labor-intensive; he once wrote in his Daybooks "I am utterly exhausted tonight after a whole day in the darkroom, making eight contact negatives from the enlarged positives."  In 1924 Weston wrote this about his darkroom process, "I have returned, after several years use of Metol-Hydroquinine open-tank" developer to a three-solution Pyro developer, and I develop one at a time in a tray instead of a dozen in a tank." Each sheet of film was viewed under either a green or an orange safelight in his darkroom, allowing him to control the individual development of a negative. He continued to use this technique for the rest of his life.  Weston was known to extensively use dodging and burning to achieve the look he wanted in his prints.
Question: Has he taken any photos that are famous?
Answer: 

Problem: Background: The Oromo people (Oromo: Oromoo; Ge'ez: 'oromo; 'Oromo) are an ethnic group inhabiting Ethiopia and parts of Kenya and Somalia. They are the largest ethnic group in Ethiopia and the wider Horn of Africa. According to the 2007 census, they represent approximately 34.5% of Ethiopia's population, while others estimate they make up about 40% of the population. With the total Ethiopian population thought to be over 102 million, the number of Oromo people exceeds 35 million in Ethiopia alone.
Context: Historically, Afaan Oromo-speaking people used their own Gadaa system of governance. Oromos also had a number of independent kingdoms, which they shared with the Sidama people. Among these were the Gibe region kingdoms of Gera, Gomma, Garo, Gumma, Jimma, Leeqa-Nekemte and Limmu-Ennarea.  The earliest known documented and detailed history of the Oromo people was by the Ethiopian monk Abba Bahrey who wrote Zenahu le Galla in 1593, though the synonymous term Gallas was mentioned in maps or elsewhere much earlier. After the 16th century, they are mentioned more often, such as in the records left by Abba Pawlos, Joao Bermudes, Jerorimo Lobo, Galawdewos, Sarsa Dengel and others. These records suggest that the Oromo were pastoral people in their history, who stayed together. Their animal herds began to expand rapidly and they needed more grazing lands. They began migrating, not together, but after separating. They lacked kings, and had elected leaders called luba based on a gada system of government instead. By the late 16th century, two major Oromo confederations emerged: Afre and Sadaqa, which respectively refer to four and three in their language, with Afre emerging from four older clans, and Sadaqa out of three. These Oromo confederations were originally based on southern parts of Ethiopia, but started moving north in the 16th century in what is termed as the "Great Oromo Migration".  According to Richard Pankhurst, an Ethiopia historian, this migration is linked to the first incursions into inland Horn of Africa by Imam Ahmad ibn Ibrahim. According to historian Marianne Bechhaus-Gerst, the migration was one of the consequences of fierce wars of attrition between Christian and Muslim armies in the Horn of Africa region in the 15th and 16th century which killed a lot of people and depopulated the regions near the Galla lands, but also probably a result of droughts in their traditional homelands. Further, they acquired horses and their gada system helped coordinate well equipped Oromo warriors who enabled fellow Oromos to advance and settle into newer regions starting in the 1520s. This expansion continued through the 17th century.  Both peaceful integration and violent competition between Oromos and other neighboring ethnicities such as the Amhara, Sidama, Afar and the Somali affected politics within the Oromo community. Between 1500 and 1800, there were waves of wars and struggle between highland Christians, coastal Muslim and polytheist population in the Horn of Africa. This caused major redistribution of populations. The northern, eastern and western movement of the Oromos from the south around 1535 mirrored the large-scale expansion by Somalis inland. The 1500-1800 period also saw relocation of the Amhara people, and helped influence contemporary ethnic politics in Ethiopia.  According to oral and literary evidence, Borana Oromo clan and Garre Somali clan mutually victimized each other in seventeenth and eighteenth centuries, particularly near their eastern borders. There were also periods of relative peace. According to Gunther Schlee, the Garre Somali clan replaced the Borana Oromo clan as the dominant ethnic group in this region. The Borana violence against their neighbors, states Schlee, was unusual and unlike their behavior inside their community where violence was considered deviant.
Question: What type of government did they have?
Answer:
Oromos also had a number of independent kingdoms, which they shared with the Sidama people.
