HDR Vault is an open project started from my personal HDR library I began in 2016. The idea is to publish a growing catalog of HDRs maps into the public domain (CC0) for personal and commercial use without any legal restrictions or copyright.
Spherical HDR maps are commonly used in visual effects and games for digital reflections and lighting. They have a strict technical requirement to build correctly and can be time consuming to capture and process in large volumes.
The work is made sustainable by support from one time contributions here and by monthly pledges on Patreon.
