Ok, the 3d model is finished, now I’m defining materials, environment, lights and composition.
The general idea is to consider the building as a work of art, a sculpture or a face looking toward the camera. So I will use a long lens with DOF, so the focus is on the building to give importance to the subject. The image will have cool colors and a minimal environment in harmony with the architecture and the materials. The only parts with warm lights will be the street lights of the walkway leading to the building and the interior of the exhibition halls, like warm is the experience that visitors live in the museum.
