Dashwood Cinema Solutions Sponsors Upcoming Stereo 3D Filmmaking Bootcamp Webinar
NewMediaWebinars.com is pleased to announce the addition of Dashwood Cinema Solutions as a Gold sponsor for the upcoming free live webinar titled “Stereo 3D Filmmaking Bootcamp” presented by James Neihouse, DP of the new Hubble 3D IMAX movie.
James Neihouse, the award winning director of photography and DP of the new Hubble 3D IMAX movie, is presenting this free “how-to” live webinar scheduled for August 26, 2010 at 10:00 am PDT. In this webinar, attendees will learn the basics of 3D/Stereo cinematography, beginning with the terminology then stepping though the process and methods of shooting in 3D. They will learn about 3D rigs, setting up cameras, the effects of interaxial distance (the distance between the lenses), convergence of the cameras, screen size, and 3D editing techniques.
As an added bonus Dashwood Cinema Solutions is also contributing two copies of Stereo3D Toolbox LE to be given away to two lucky attendees during the live webinar.
“We are happy to have Dashwood Cinema Solutions as a partner and sponsor in this upcoming free live webinar,” states Marcelo Lewin, Founder and CEO of NewMediaWebinars.com. “They offer a great solution for 3D filmmakers and we are sure that all of our attendees appreciate their support as well!”

Transitioning to shooting in 3D
The Panasonic AG-3DA1 is a one-piece HD camcorder that eliminates 90 percent of the setup hassles associated with conventional 3D rigs. A useful readout in the camera viewfinder indicates the acceptable divergence for 77in. and 200in. screens.
The eyes of a typical adult human being are approximately 60mm to 70mm apart. To reproduce the human perspective as closely as possible, Panasonic AG-3DA1 engineers adopted a fixed inter-axial distance of 60mm, thus ensuring at normal operating distances from 10 meters to 100 meters that the roundness of objects and background position appear life-like, a key consideration for shooters looking to mimic to the extent possible the human experience on earth.
The 3DA1 features a unique 3D guide for advising shooters of the practical depth range in a scene. Two 3D guide settings are provided for use with 42in. and 77in. screens.
If we narrow the interocular (IO) distance in the camera to only 3mm, we would produce a perspective suggestive of an insect with eyes 3mm apart. The narrow IO may make sense for a story about enterprising mosquitoes, or for shooting close-ups of smallish objects to reduce the severe convergence angle that leads to 3D headaches. Conversely, if we’re shooting King Kong in 3D, we might increase the IO substantially to 2 meters or more to reflect the giant ape’s perspective; the increased amount of 3D in the scene motivated by the much wider positioning of the eyes in King Kong’s skull.
