NOTE: This image is a panorama of Pittsburgh consisting of 9 frames that were merged or stitched in Hugin. As a result, this image necessarily underwent some form of digital manipulation. These manipulations may include blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different from reality at the points where multiple images were combined. This manipulation is often required due to lens, perspective, and parallax distortions.
