I think this also applies to lighting design – wanting to see exactly what it is good for and how it is supposed to work.
I don't need any visualization for lighting design. For me, this topic is more about someone planning the whole thing economically with sense, understanding, and a broad market overview. In the end, only Lampen Hugo around the corner will be happy if he "plans" it for me.
The lighting designer also calculates the lighting requirements and uses mathematical methods. This can certainly be more efficient than if just any electrician randomly covers the ceiling with spots. He also develops a concept for outside.
