Stereoscopic 3D Filmmaking: An Introduction
The document discusses the principles and techniques of stereoscopic 3D filmmaking, explaining how it creates the perception of depth through two images for the left and right eyes. It outlines the benefits of 3D in filmmaking, including enhanced visual information and creative possibilities, while also addressing the challenges in achieving a precise 3D effect. The document emphasizes the importance of correctly capturing and presenting these images for the brain to merge them into a cohesive 3D experience.

- 3. But First… • Theword stereoscopy derives from the Greek "ςτερεόσ" (stereos), "firm, solid" & "ςκοπέω" (skopeō), "to look", "to see“ • We are seeing something solid – unlike 2D it’s something that has shape and volume. © 2013 Enhanced Dimensions
- 4. Why make a3D Film? • 3D Film is not a Genre – – – • Make your film in colour, with sound... and possibly in 3D? Stereo 3D is another item in your filmmaking palette Consider Stereo 3D and how it can be used 3D Benefits – – – – – Stereo 3D delivers more visual information Stereo 3D can direct focus, the same as other film techniques Can be used creatively to create vast open space, or confine us claustrophobically Can add surprising small details, adding realism or magic to the scene Can visually clarify detail in density © 2013 Enhanced Dimensions

- 6. How does Stereoscopywork? • Emulates human vision with two images - one for left, one for right. • A filter of some sort splits the image and directs appropriate image to appropriate eye • The brain merges into 3D © 2013 Enhanced Dimensions
- 7. Fooling our eyesinto perceiving depth • 65mm (2.5 inches) inter-occular distance • This is an important measurement, that impacts on much of 3D film theory © 2013 Enhanced Dimensions

- 14. Basics Summary • Capturea left & right view • Deliver the right & left view to the viewer • The brain does the rest... Well sort of... • Sounds simple. How come it’s such a big deal then? • The challenge isn’t in creating it, the skill is in the precision control of the stereoscopic 3D effect. © 2013 Enhanced Dimensions
