As we have mentioned in the past, we feel that its very important to capture the amazing Architecture at San Francisco city hall. We do this by using high quality wide angle lenses and also fish-eyes. The photo above was actually captured with a a Fish Eye lens which is why there is some distortion and curvature. We think it still works since it highlights the building details. We would not want to use this type of camera lens for all of our city hall images, but it works well in small doses.
