The magic lantern or laterna magica is an early type of image projector employing painted pictures or photographs on sheets of glass, a lens and a bright light source. It was developed in the 17th century and commonly used for educational and entertainment purposes.
Magic Lantern is keystroke logging software developed by the United States' Federal Bureau of Investigation. Magic Lantern was first reported in a column by Bob Sullivan of MSNBC on 20 November 2001 and by Ted Bridis of the Associated Press.
Magic Lantern is a firmware add-on, originally written for the Canon EOS 5D Mark II by Trammell Hudson in 2009, and ported to the 550D/T2i/Kiss X4 (1.0.8) in July 2010 by the same author. The current principal developer is known as A1ex and there are now versions for most Canon DSLR's.
Because installing Magic Lantern does not replace the stock Canon firmware or modify the ROM but rather runs alongside it, it is both easy to remove and carries little risk. The DSLR checks a "boot flag" in its re-writable memory, and if set, reads from a flash card to get the additional firmware routines. Each time the camera is started, there is an option to disable Magic Lantern.
A similar FOSS project is CHDK for most Canon point-and-shoot cameras.
