San Francisco Ferry Building Mosaic

Panorama built up of 6 images. Theoretically, could have simply moved further back to take this picture as a single shot, but that was not possible as there were trees, poles, medians, etc in the way. The difficulties in this panorama were the people and the tree. Handheld shots, no tripod.
The Six 'source' pictures. Note the different perspectives of the building. Could have got by with only 4 pictures (4 outer corners) but the middle two pictures helped with the sky, and also helped deal with the people, and with shading variations.
