San Francisco from Corona Heights ( Vignetting off ) by Stoney Vintson

San Francisco from Corona Heights ( Vignetting off ), No polarizer, End of day at 63 to 64 degrees fairenheight which results in "heat shimmer" for objects that are far away. Objects that are closer are not effected by heat shimmer at these temperatures as the light does not need to travel through as much atmosphere to the camera lens. Canon 5D Mark II, 500mm f4 and a 1.4x teleconverter for an effective focal length of 700mm. It would be better to capture this panorama earlier in the morning when temperatures and wind is lower. You can shoot a reference at the begining of each row or few rows for white balance and exposure, though the angle of the shadows would change. The stitching result is a very good start, but the ability to make manual adjustments numerically would allow me to get quality results without using another tool. If you did not want to add manual numeric adjustments of yaw, pitch, roll, and % contribution, you could output the alignment to panotools and two other stitchers could be used to make manual numeric adjustments, horizon correction ( leveling ), cropping, exposure, etc.
