Solar shading design can be tricky. Too much shading and your interiors are dark and lifeless. Too little shading and spaces are too bright and internal objects are silhouetted against the glare. Poorly designed solar shading can also limit views, voiding the whole point of windows.

This shading on the De Young Museum in San Francisco is an interesting balance, creating good views while filtering light at high level so that interiors still have good daylighting. The shading device is made of punched metal.
