Until now, photographers and filmmakers had to use special equipment if they wanted to change the focus area in post-processing or reproduce an object three-dimensionally. The start-up K-Lens has now developed a special lens that can turn any standard camera into a 3-D camera. What began as a research project of the Max Planck Institute for Informatics and Saarland University, and was developed further with the help of the IT Inkubator, is expected to become available as a commercial product starting in 2019.
