The Photographer's Viewfinder provides the chief photographer 
with a view of the terrain such that he may determine drift, image 
rate, and cloud obscuration of terrain. The presentation to the oper 
ator is of the field lens type and is integrated within the Photographer's 
console. The structure, however, is supported independently so that 
the console does not impose any forces upon the viewfinder tube. The * 
primary specifications for the viewfinder are listed below in Table V.
