2. 35 mm equivalent focal length - Wikipedia

   en.wikipedia.org/wiki/35_mm_equivalent_focal_length

   35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...

3. Film-out - Wikipedia

   en.wikipedia.org/wiki/Film-out

   Film-out of standard-definition video – or any source that has an incompatible frame rate – is the up-conversion of video media to film for theatrical viewing. The video-to-film conversion process consists of two major steps: first, the conversion of video into digital film frames which are then stored on a computer or on HD videotape; and secondly, the printing of these digital film ...

4. Crop factor - Wikipedia

   en.wikipedia.org/wiki/Crop_factor

   A 50 mm lens on an APS-C format (crop factor 1.6) images a slightly smaller field of view than a 70 mm lens on a 35 mm camera. The terms crop factor and focal length multiplier were coined to help 35 mm film format SLR photographers understand how their existing ranges of lenses would perform on newly introduced DSLR cameras which had sensors smaller than the 35 mm film format, but often ...

   The work was performed at the Digital Film Lab in Copenhagen, using a Spirit Datacine to transfer the entire film to digital files at 2K resolution. The digital intermediate process was also used to perform a digital blowup of the film's original Super 16 source format to a 35mm output. [7] [8]

6. Teleconverter - Wikipedia

   en.wikipedia.org/wiki/Teleconverter

   For example, a 2× teleconverter for a 35 mm camera enlarges the central 12×18 mm part of an image to the size of 24×36 mm in the standard 35 mm film format. Teleconverters are typically made in 1.4×, 1.7×, 2× and 3× variants, with 1.4× and 2× being the most common. A 2× teleconverter doubles the apparent focal length of a given lens ...

7. Television standards conversion - Wikipedia

   en.wikipedia.org/wiki/Television_standards...

   These were the high-end converters of the 1960s and 1970s. Image Transform in Universal City, California, used the Fernseh converter and in the 1980s made their own custom digital converter. This was also a larger three-rack device. As digital memory size became larger in smaller packages, converters became the size of a microwave oven. Today ...
