Over the past 10 years 3D technology has become an increasingly popular tool in film and television production
Liverpool, UK - 17 June 2010: Scientists at the University of Liverpool are providing training for North West filmmakers to enhance understanding of how the human brain processes the visual information in 3D film and television. Researchers at the University's Vision Laboratory at the School of Psychology are leading an industry workshop to demonstrate the common problems that filmmakers face in creating naturalistic 3D film images. They will also discuss the scientific factors that need to be considered to ensure that the human visual system can easily process 3D images. Study suggests that failure to mimic the visual system in 3D film has similar effects to the visual disturbances that accompany the toxic effects of alcohol, poison or motions of the inner ear that lead to seasickness. Inappropriate camera alignments at the editing stage can also induce eyestrain by positioning images too close or too far apart within the line of sight, or scaling the size of objects incorrectly. Dr Bernard Harper, 3D specialist at the University, explains: "3D film images are created using processes that attempt to mimic the binocular nature of human vision. Each eye sees a slightly different two-dimensional image and the brain uses the difference to create a third dimension, which gives an image or object depth.
