Hello everyone,
I’m excited to share that we were able to put together a very interesting program for the upcoming Radiance and HDR workshops (see the overview below).
If you haven’t registered yet, now is the perfect time — we still have a few spots available. We can even accommodate 1–2 last-minute presenters, so don’t hesitate to reach out if you’d like to contribute.
Beyond the workshops themselves, Lausanne has plenty to offer this time of year: late-summer sunshine, pleasant 25° temperatures, beautiful hiking trails, and of course the chance to enjoy a swim in the lake.
We’re looking forward to welcoming you!
Here the link for the workshops and registration: Radiance and HDR workshop 2025 ‒ LIPID ‐ EPFL
