35 mm film is the film gauge most commonly used for motion pictures and chemical still photography (see 135 film). The name of the gauge refers to the width of the photographic film, which consists of strips 34.98 ±0.03 mm (1.377 ±0.001 inches) wide. The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. For still photography, the standard frame has eight perforations on each side.
A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th century and early 20th century, ranging from 13 mm to 75 mm (0.51–2.95 in), as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as 1.375 inches, was introduced in 1892 by William Dickson and Thomas Edison, using film stock supplied by George Eastman. Film 35 mm wide with four perforations per frame became accepted as the international standard gauge in 1909, and remained by far the dominant film gauge for image origination and projection until the advent of digital photography and cinematography, despite challenges from smaller and larger gauges, because its size allowed for a relatively good trade-off between the cost of the film stock and the quality of the images captured.
"Fotografía" (English: "Photograph") is a song recorded by Juanes and Nelly Furtado for Juanes' second studio album, Un Día Normal (2002).
The duet, which was followed by another ("Te Busqué" on Furtado's 2006 studio album, Loose), was extremely commercially successful: it reached number one on the U.S. Billboard Hot Latin Tracks chart and in Latin American countries such as Argentina, Chile, Mexico and Peru. The song re-introduced Furtado to the Latin American market and paved the way for Furtado's success with Folklore, her second album, in the region.
