Andrey Tarkovsky is one of the best cinema directors and He was writing about the compositions of Vittore Carpaccio 15th century.
I found his pictures at

and his one of pictures from 1494 are very interesting. It is anamorphic and 4 meters wide.

Is there a lens for ultra large format which will be able to give this picture or rails are enough ?
