Intensive Workshop with Wilfried Kramb: From concept to impact
Light is more than illumination – it creates atmosphere, emotion, and impact. In our new three-day intensive workshop with renowned lighting designer Wilfried Kramb, creativity, conceptual thinking, and hands-on exploration take center stage. From the first sketch to practical testing in the White Lab, ideas evolve into a coherent lighting concept. We spoke with Wilfried about why light is so much more than technology, how he found his passion, and why this workshop will fundamentally sharpen the way we see spaces and light.
GLDF
