Nikon recently opened up Nikon Cinema, a website dedicated to HD SLR motion projects that have been created with Nikon hardware. The website currently hosts 3 short motion projects that have been shot with the Nikon D4, D800, D600 and various Nikkor glass.
The three films include Joyride by Sandro, Why by Corey Rich and Chasing The Light by Florian and Salomon Schulz. The website is loaded with great information about what it took to create each project, a look behind the scenes of the productions and what gear was used.
The website is a self promo, no denying that, but there is a lot of great information throughout the site about shooting motion work. Aside from the videos, the "Making the Shot" section is a nice interactive look at the extra gear used in the productions. It is well worth the time to dig around the site and check out the work.
