My name is Greg Zaal, I'm a CG artist and Open Source advocate.
HDRI Haven is where you can find high quality HDRIs for free, no catch.
All HDRIs here are CC0 (public domain). No paywalls, accounts or email spam. Just download what you want, and use it however.
Since all of the income for this site comes from the community, it's only fair that the community gets to decide what happens with it.
All Patrons have access to a private Trello board where they can add ideas and vote on new locations, trips, and generally decide where the money goes.
If you want to get involved and help keep this site alive at the same time, consider supporting HDRI Haven on Patreon.
