The independent cinema technology organization CTC has announced the publication of a report on the causes of ghosting in 3D films during CineEurope in Barcelona. In the report, the organization concludes that several factors in the cinema projection chain can contribute to the effect. Ghosting is the visual effect that occurs when image information intended for one eye seeps into the other eye. The effect is a disruption of the 3D sensation, as additional shadow effects and image doubling are created in the image. The intensity of the effect can vary per film and even per scene, and is especially visible in the subtitles or closing credits.
