Radiance and HDR workshop 2025

 

August 27-29, Lausanne, Switzerland 

The Radiance Workshop is the annual meeting of the Radiance software community, alternating between Europe and North America. This year’s event will take place in Lausanne, Switzerland, and will include a special HDR workshop on the third day, organized by the HiDyn project consortium.

The workshop brings together researchers, practitioners, educators, and enthusiasts in daylighting, rendering, and lighting simulation to present and discuss their Radiance-related work. Whether you’re new to the software or an experienced user, all contributions are welcome. Speakers benefit from in-depth discussions, valuable feedback, and a discounted registration fee.

This year’s program will also feature a dedicated afternoon focused on material modelling—a core topic in almost all Radiance workflows. Contributions related to material characterization, modeling techniques, or case studies are especially encouraged for this session.

The third day will be devoted to a hands-on HDR workshop. Experienced users can present their work and refine HDR imaging workflows. For beginners, the session offers a guided introduction to HDR imaging—covering core principles, image generation, and practical camera calibration techniques—providing a strong foundation in state-of-the-art methods.
