The size of individual mirrors was still small: the 17 seemingly large window-like panes in the Hall of Mirrors are in fact stitched from 357 small pieces of mirror glass. [12] In 1687, Bernard Perrot [ fr ] developed a process of glass casting that enabled first truly large glass mirrors, impossible to make using the traditional glass blowing ...

[ 22 ] [ 23 ] Using a monolithic mirror much larger than the 5-meter Hale or 6-meter BTA-6 is prohibitively expensive due to the cost of both the mirror, and the massive structure needed to support it.

The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...
