Time-lapse photography is a very interesting format to make visible dynamics happening in our environment on a different timescale.
Time-lapse is very popular in making visible the weather evolution in a scenic landscape, or to show the business of an urban scene of city life. While already on land it is relatively difficult to correctly orchestrate a time-lapse capture this is by orders of magnitude more difficult when trying to capture underwater sceneries.
Here are some examples found at the Vimeo archive. Some of them are very interesting artistic productions.
Besides the excellent performance of the Nikon D800 camera for still photography, the camera has very good reputation if used in videography. I recorded once some short video sequences underwater. from a shallow dive at Middle Reef in Soma Bay, Egypt. And the result is very nice for an available light sequence and first try.
I do not know how often the Nikon D800 is used in underwater videography. Some other a little bit longer examples by videographer Rick Scott I found on YouTube:
Have a look at this short documentary on todays SUPER 8 film movie makers.
Also here people are following a hybrid process. The movie is shot on film, film gets developed and finally scanned image by image and edited in a computer.
As this seems to become more and more a common workflow Kodak already offers the most of the process as a service. And many people love it.
