My One Picture a Day for today, Exploded View, was kinda weak. So here’s a bonus photograph of St Paul Cathedral in Oakland, Pittsburgh, PA. It is from the same visit as the Battleship Organ post. I took this in the evening. The blue glow of the windows is a rather interesting effect. Taken with the Tokina 11-16mm wide angle. Perspective corrected with PTLens, which I just bought a license for. It really is an easy way to fix perspective. I tried several free alternatives, but they were a pain to use. PTLens does it quickly and easily right from an Aperture plugin. And at a great price compared to DxO or Photoshop.
