I took this photo outside of the Sunvalley Mall. It was a wonderful weather on that day. I like the illusion of looking up, it could help me to make a great composition of the entire photo and also make a clear image of the special housetop. For the final image, I corrected it with 35% capacity of "screen" to make the whole photo be brighter at first. Then, I used "level" to tuned up the color of the architecture, the sky so it became more vivid. Finally, I used the S "curve" to adjust the contrast of different two part of the housetop which had different intensity distribution. Therefore, the left part of it would be darker and the right hand side would be brighter. Different degree of light emphasized the shape and structure of the architecture. People could be easy to find the key point of this photograph and realize how beautiful it is.
