equipped with an Aviogon lens (f — 115 mm, 180 X 180 mm). These photographs 
were made on five different fligbt missions and two rolls of film were used, so that each 
of the five sets of stereopairs could be considered to have been taken under different 
conditions. 
In the spring of 1959 a few more stereopairs were taken over the Renfrew test 
area with a superwide-ange camera (Wild Super-Aviogon, f — 88 mm, 230 X 230 mm). 
One pair of diapositives from these photographs was sent to participants requesting it.
