The view from Coit Tower in San Francisco. Programs, PTgui and Photoshop. I used eight vertical pictures taken with a Canon Xt (350D) and a 18 mm lense. The pictures were taken through windows around the top of the tower which is about 20ft+ (6+ m) in diameter. This made for some tricky stitching. The windows are Plexiglass, very dirty and scratched. I was trying for a 360dg picture but the combination of the glare off the windows and being 20ft off the lenses Nodal Point I had to settle for two 180dg.
