Given the question: Information: - Louis-Napoleon Bonaparte (born Charles-Louis Napoleon Bonaparte; 20 April 1808 9 January 1873) was the only President (184852) of the French Second Republic and, as Napoleon III, the Emperor (185270) of the Second French Empire. He was the nephew and heir of Napoleon I. He was the first President of France to be elected by a direct popular vote. He was blocked by the Constitution and Parliament from running for a second term, so he organized a "coup d'etat" in 1851 and then took the throne as Napoleon III on 2 December 1852, the forty-eighth anniversary of Napoleon I's coronation. He remains the longest-serving French head of state since the French Revolution. - The carte de visite ("visiting card"), abbreviated CdV, was a type of small photograph which was patented in Paris by photographer Andre Adolphe Eugene Disderi in 1854, although first used by Louis Dodero. It was usually made of an albumen print, which was a thin paper photograph mounted on a thicker paper card. The size of a carte de visite is mounted on a card sized . In 1854, Disderi had also patented a method of taking eight separate negatives on a single plate, which reduced production costs. The Carte de Visite was slow to gain widespread use until 1859, when Disderi published Emperor Napoleon III's photos in this format. This made the format an overnight success. The new invention was so popular it was known as "cardomania" and it spread throughout Europe and then quickly to America and the rest of the world. - Andre-Adolphe-Eugene Disderi (28 March 1819 4 October 1889) was a French photographer who started his photographic career as a daguerreotypist but gained greater fame for patenting his version of the "carte de visite," a small photographic image which was mounted on a card. Disderi, a brilliant showman, made this system of mass-production portraiture world famous. - Not much is known about Louis Dodero of Marseilles other than he is credited for inventing the Carte de visite . More often than not , this credit is erroneously given to Andre - Adolphe - Eugene Disderi who popularised the use of this type of photograph mostly because of his good fortune to be in the right place and the right time during Napoleon III 's visit to his studio . What is the relationship between 'louis dodero' and 'photographer'?
