A very special lens is currently being developed in Saarbrücken -- with the K|Lens it should be possible to take light field shots with practically any camera, which allow a complete (subsequent) control of sharpness and blur, depth-based cropping, perspective changes and 3D shots as well as a complete access to the depth planes of the shot.
The heart of the optical system is a sophisticated mirror arrangement, which splits the incident light rays into different perspectives, which are all recorded simultaneously by the (normal) camera sensor. Subsequently, a depth map of the view is to be calculated using a software plug-in in addition to the actual image. Based on the depth information, different image areas can be segmented in order to post-process them separately or to release them -- it would then no longer be necessary to shoot them in front of a carefully selected green screen, since it is, so to speak, keyed in space, no longer based on color channels.
In fact, with the K|Lens it should be possible to control sharpness and blur, multi-layer editing as well as the creation of natural 3D, VR/AR, holo content, even with moving images, but as so often not directly to the start. A first prototype should be finished in 2019. The special lens with 80mm fixed focal length should be compatible with all common digital cameras and lens mounts and cover a full frame circle. The weight is expected to be less than one kilogram.
The project is based on a research project of the Max Planck Institute for Computer Science and the University of Saarland and was awarded the Start-Up Award of the Photoindustrie-Verband at the Photokina. K|Lens is pleased about feedback from the community, by the way, who finds the project interesting, can contribute in the context of a Co-Development-Program.
