Activities and Products 
Kodak started with a new idea—in April 1880. George 
Eastman was sure that everybody would be able to 
take photos, if it only could be done in a simpler and 
cheaper way. Today his enterprise is a gigantic orga 
nization which produces all sorts of photographic 
products, but which also does a large business (nearly 
40 per cent of its total) in cellulose products, chemi 
cals, and non-photographic equipment, for the Ameri 
can defence program and other customers. 
In the United States alone, the Eastman Kodak Co. 
employs about 54,000 people, of whom about 37,000 
work in Rochester. As a whole, Eastman Kodak em 
ploys about 74,000 persons. Of Eastman’s photographic 
production, only 1/3 is now used by amateurs. The 
industries, the professional photographers, the commer 
cial enterprises, and the scientists take the rest. The 
colossal Kodak enterprise has a position of almost 
unchallenged supremacy in photographic x4merica; it 
builds this position partly on the good-will of the 
Kodak name, but also an unequalled program of photo 
graphic research—in the research laboratory alone, 
Eastman employs more than 600 persons.

Exhibit 
The exhibit is designed to illustrate the complete 
range of Ilford films, plates, papers, and processing 
chemicals available for photogrammetric work, from 
the taking of the actual aerial photographs to the 
completion of a finished map. The main display, 
which is shown by courtesy of the Director of Mili 
tary Survey, War Office, is accordingly devoted to a 
sectionalized demonstration of the fourteen stages 
involved, and the Ilford materials used, in preparing 
an Air Ministry map in twelve colours from the origi 
nal aerial negatives. Other examples of the uses of 
Ilford materials in aerial photography are illustrated 
by a comprehensive display of enlargements from neg 
atives on Ilford Hyperpan Aerial and Ilford HP3 
Aerial films. 
Activities and Products 
Manufacturers of sensitized materials, chemicals and 
accessories for all branches of photography.

The AGA Geodimeter 
The AGA Geodimeter is a revolutionary distance 
surveying device and the result of many years re 
search in the electronic-optical field by Dr. Erik Berg 
strand in an effort to determine a better value for 
the velocity of light. Making use of this universally 
accepted constant, the present models — NASM-2A 
and NASM-3 — are capable of measuring distances 
of up to 45 km. inside an hour with an accuracy of 
within two parts in a million. The NASM-2A is the 
more accurate of the two models with a built-in cal 
ibration system, while the lighter NASM-3, although 
less accurate and with a lower range, is well suited 
for surveying in rugged terrain where portability is 
essential. Both instruments can be used for a variety 
of surveying tasks such as base line measuring, trian 
gulation, photogrammetry etc. 
Activities and Products 
At present a world-wide concern with plants and fac 
tories in 24 countries, AGA was founded by Nobel 
Prize winner, Gustaf Dalén, whose ingenious inven 
tions enabled lighthouses to function unattended for 
long intervals by greatly reducing gas consumption. 
Subsequent development has found AGA manufac 
turing gas and electric beacons and other navigational 
devices as well as a variety of equipment for gas 
welding, medical use, sound film, electronic and op 
tical instruments plus a complete line of radio and 
television apparatus. More recently AGA has emerged 
as a leading producer of electro-optical precision in 
struments such as anamorphic cinema projectors with 
stereoscopic sound and was the original producer of 
the land surveying instrument called »Geodimeter» 
now in extensive use for surveying the world over.
