Same stairwell as Day 23, but shows context. As you can see the architect carried the triangle in the concrete shaft motif to the treatment of the ceiling in the shaft. Natural light is introduce through a row of glass blocks at the very top of the shaft. My favorite piece of modern architecture at Yale... well, a tie with the marvel that is the Beinecke.
The triangle in a circle is quite a strong symbol, hermetically. The architect's done well but you've done even better to capture the tones and textures....love the subtle tone-mapped look to your processing Seeain.
