The Department of Reconstruction and Town Planning uses film for all its 
photography. Makes used are French Kodak Pathe or Guilleminot, or Belgian 
Gaevert Panchro 33°. The base is triacetate or aceto-buterate. Processing is on 
French Sauret equipment with bath temperatures from 18 to 23°C. Storage 
before and after exposure and processing is at 18°C, 60% relative humidity. 
Germany 
Films used are Agfa Aeropan, Agfa Aerorapid, Agfa Infrared, Agfa Colour, 
and recently Gaevert Avi Panchro Microgran 27°. The resolving power of 
Aerorapid is given as 21 microns and of Aeropan B as 16 microns with a radial 
line test plate. The Agfa materials are on a cellulose nitrate base. Processing 
is carried out on the rewinding equipment of Messrs. Volk with processing solu 
tion temperatures from 18 to 20°C. No routine sensitometric control is used. 
Drying drums of approximately 1 -5 metres diameter ure used. Film is supplied 
in taped tins and stored, after processing, in the same containers. There is no 
special control of temperature and humidity. 
India 
Safety Topographic base film is used and is processed in Morse developing 
units with solution temperatures of 68 to 74°F. The gamma used is varied in 
accordance with air information reports. Routine sensitometric control is used. 
Film is supplied in hermetically sealed tins and when possible is stored before 
exposure at less than 7()°F. After processing the film is reconditioned and stored 
in an air-conditioned room. 
Italy 
Negative materials used are Ferrania Panchromatic glass plates and Gae 
vert Avi Panchro Microgran film. Plates are processed in lots of 24 in stainless 
steel tanks. Film is processed by mechanical rewinding between two rolls 
and dried on large rotating drums. Processing solution temperatures are 18°C 
±4°. Gammas used are less than 1. There is no routine sensitometric control. 
Film is supplied in metal containers and is stored both before and after exposure 
at 10 to 20°C without humidity control. 
Netherlands 
Kodak Aerographic Super XX film is used exclusively and is processed in 
Fairchild-Smith developing and drying apparatus with a solution temperature of 
18°C. The tolerance on this temperature is + 1°C for the developer and ±3°C 
for washing and fixing. Development is to a gamma of 1 • 2 or 1 • 3 as determined 
by occasional sensitometric control. No routine sensitometric control is used. 
No special control of the equilibrium condition of the film is attempted as it is 
considered more desirable to use a plate camera such as the RC-7 for exact 
work. Film is supplied in sealed tins and storage conditions aim at 16 to 18°C 
with 65% relative humidity, but no special control is used to obtain these 
conditions.
