be exposed on to the film, Thanks to the introduction of
intermediate f-stops, the sensitivity of the automatic
exposure control has been increased, The latest addition
to Jena’s aerial photography equipment is the NCU 2000
Navigation & Control Unit developed in 1987,
which now permits the camera system to be operated by a
single person, The standard control unit and the NCU fit
the same mount, so that conversion between the two modes
of operation can be effected quickly and easily.
3. SUMMARY
Since 1911, the Jena optical works have made outstanding
contributions to the development of aerial photography.
The Jena scientists and engineers have always been guided
by the most advanced international standards, not seldom
setting new standards themselves,
The Jena optical works today live up tO that tradition,
which is made evident by such extraordinary products as
the MKF-6 or the LMK, This report, without claiming comple-
teness, outlines the history of aerial camera design at
Jena by way of significant product developments - from the
balloon camera to the LMK-1000, This is, at the same time,
part of the history of photogrammetry,
