Full screen (film technology)

The full frame comes from pioneers William KL Dickson , Birt Acres and Lumière, who worked with 35mm film . It was set at the first international congress of film manufacturers in Paris in 1909 with the size of 18 by 24 mm, of which the section of 17.7 by 23.6 mm should be shown. At that time it was agreed on the film step of 19 millimeters instead of 19.05 (¾ "), which resulted in a height of 1.2 millimeters between the phase images , which is sufficient for the production of durable splices .

The full screen has been honored again in the attempts at CinemaScope . Another return to the full screen came with the so-called Super-35. It is the basis of all cinematographic work with normal film , because it represents the largest usable area with normal film step, which can also be mounted in one volume, i.e. H. the individual sections are lined up in a band. Thanks to the symmetry, you can perform a few more tricks with the full screen than with the normal screen , for example backwards with the camera upside down.

Colloquially, the term full image is often used in connection with an output device, regardless of the aspect ratio, in which the image area is completely filled, i.e. without black bars ( letterbox ).
