This phenomenon is known as Oersted's law. He also discovered aluminium, a ...
The first consumer camera with a liquid crystal display on the back was the Casio QV-10 developed by a team led by Hiroyuki Suetaka in 1995. The first camera to use CompactFlash was the Kodak DC-25 in 1996. [52] The first camera that offered the ability to record video clips may have been the Ricoh RDC-1 in 1995.
View from the Window at Le Gras 1826 or 1827, believed to be the earliest surviving camera photograph. [1] Original (left) and colorized reoriented enhancement (right).. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection; the second is the discovery that some substances are visibly altered by exposure to light.

Hans Christian Ørsted. Hans Christian Ørsted (14 August 1777 – 9 March 1851) was a Danish physicist and chemist, influenced by the thinking of Immanuel Kant. He is best known for discovering the relationship between electricity and magnetism known as electromagnetism. From 1806, Ørsted was a professor at the University of Copenhagen.
H. Tønnies: Jens Bangs Stenhus in Aalborg (1890). The technique of carte de visite photography was brought to Denmark by Rudolph Striegler in 1860. It spread rapidly and by the 1870s provided a cheap and attractive alternative to portrait painting for photographers such as Ludvig Grundtvig (1836–1901) and Adolph Lønborg (1835–1916) in Copenhagen, and Heinrich Tønnies (1856–1903) who ...
The 1820s was a decade of the Gregorian calendar that began on January 1, 1820, and ended on December 31, 1829.. It saw the rise of the First Industrial Revolution. Photography, rail transport, and the textile industry were among those that largely developed and grew prominent over the decade, as technology advanced significantly.
English inventor Francis Ronalds built the first working electric telegraph. 1820: Danish physicist Hans Christian Ørsted accidentally discovered that an electric field creates a magnetic field. 1820: One week after Ørsted's discovery, French physicist André-Marie Ampère published his law. He also proposed the right-hand screw rule. 1821
1820 – Hans Christian Ørsted, Danish physicist and chemist, develops an experiment in which he notices a compass needle is deflected from magnetic north when an electric current from the battery he was using was switched on and off, convincing him that magnetic fields radiate from all sides of a live wire just as light and heat do ...
