I recently returned from a very productive trip, diving the wrecks of the Shetland Islands here in the UK. A few highlights were these:-
Firstly, the Fraoch Ban, a small fishing boat in 30m:-
Then the submarine HMS E49 complete with diver laying alongside the wreck for scale:-
And finally, the largest underwater subject I have covered to date; the SS Gwladmena, At 70m long and 10m wide this wreck took two dives, over two and a half hours in the water and 2000 frames to build:-
This last wreck is about the limit of what can be achieved at a depth of 38m....but I am working on a plan to improve scanning efficiency...full report in November on how that turns out.
The models have derived some rather nice 2D orthophotos too:-
