Because the Japanese military imposed strict order, any photography that included topographic features, military bases, or indeed any photo whose field of vision extended downward more than 45 degrees had to be approved by the military police. Thus it was difficult for ordinary people to photograph freely outdoors.
由於日軍管制甚嚴，凡是山川水景、軍事要塞，甚至向下斜四十五度的拍攝，都要經憲兵司令部的審查，因此普通人很難自由拍攝。
