ABSTRACT
This presentation introduces the OpenVPCal toolset, an open source in-camera visual effects calibration framework. The toolset includes reference patch generation, creation of calibration color transforms, and custom 1D roll off lookup tables (LUTs) to control content brightness while attempting to maintain a linear light output from the LED panels. The resulting transforms can be expressed via an OpenColorIO Config [OCIO Contributors 2022] file, making tracking and transport easier for productions to manage and reproduce. We hope that by making this workflow open source and accessible, it will increase dialogue between practitioners in the space, leading to new novel improvements for creating more amazing content worldwide.

Open source software licenses: Strong-copyleft, non-copyleft, or somewhere in between?
Studies on open source software (OSS) have shown that the license under which an OSS is released has an impact on the success or failure of the software. In this paper, we model the relationship between an OSS developer's utility, the effort that goes ...
