The rotaUon of the principal frame of the Wild A8 autograph about 
the axis /fig.3/ by an ¿ngle inclines equally both cameras 1» the 
longitudinal direction by the same angle. If the caTOrss have had 
already tieir "inner 6 ’ inclinations /©.g*^ and P / thin their rela 
tive positions and the positions in regard to the line (TO 9 * don't 
©hang© by this rotation» Thus it is eary to coneXude, that the final 
result of these two inclinations» that is the outer angle of inclina 
tion of the air photograph will be equal to the sum of the two longitu 
dinal inclinations» via*

We have in this equation the element^® which is the angle of 
longitudinal inclination of the left or right photograph? in the pre 
sent methods of orientation it was the element of the relative orienta 
tion of these photographs» The element was introduced for the ls- 
©g 
veiling of the model» After these two operations: relative orientation 
and rotation of the model we have obtained a certain final position^ - 
different for the two cameras - and this positions were equal to the alge 
braic sum of the two angles of inclination®according to the formula /1/» 
For the lateral inclinations of the photographs these two operations 
follow one after another too» but the designer of the Wild A8 autograph 
hasn^t realized the same mechanical solution and this is why we have to 
introduce equal lateral inclinations to the left and right cameras of the 
autograph separately. 
Thus» analogically to9^* oan write identical equation for the 
both operations ofCJ» nemelys
