Cuando España se desnudó

Working men and women leave through the main gate of the Lumière factory in Lyon, France. Filmed on 22 March 1895, it is often referred to as the first real motion picture ever made, although Louis Le Prince's 1888 Roundhay Garden Scene pre-dated it by seven years. Three separate versions of this film exist, which differ from one another in numerous ways. The first version features a carriage drawn by one horse, while in the second version the carriage is drawn by two horses, and there is no carriage at all in the third version. The clothing style is also different between the three versions, demonstrating the different seasons in which each was filmed. This film was made in the 35 mm format with an aspect ratio of 1.33:1, and at a speed of 16 frames per second. At that rate, the 17 meters of film length provided a duration of 46 seconds, holding a total of 800 frames.

The earliest surviving motion-picture film, and believed to be one of the very first moving images ever created, was shot by Louis Aimé Augustin Le Prince using the LPCCP Type-1 MkII single-lens camera. It was taken on paper-based photographic film in the garden of Oakwood Grange, the Whitley family house in Roundhay, Leeds, West Riding of Yorkshire (UK), on 14 October 1888. The film shows Adolphe Le Prince (Le Prince’s son), Mrs. Sarah Whitley (Le Prince’s mother-in-law), Joseph Whitley, and Miss Harriet Hartley walking around in circles, laughing to themselves, and staying within the area framed by the camera. Roundhay Garden Scene is often associated with a recording speed of around 12 frames per second and runs for about 2 to 3 seconds.
