Old late 19th century searchlight emplacement on North Head, Auckland, New Zealand. This model was a test to see if flash photography in the dark interior areas would be compatible with the sunlit exterior photos. The photogrammetry software handled it ok, there are a few messy areas where i didn't take enough photos.
