Leifs - It's worth noting that that was shot with the Canon 100-400mm zoom which vignettes pretty strongly.

Re: Burj Khalifa (world's tallest building) 3.7 gigapixel

Something just occurred to me.

The banding would appear to be created along the direction in which the pano was shot - if you shoot in rows, the banding is stronger in the horizontal. If you shoot in columns, its stronger in the vertical.

Even in that Dubai 45GP one in the above link, despite the fact that the lense vignettes strongly, there is little to no banding horizontally. It's all in the vertical (that one was shot in columns).

These days I shoot pretty much exclusively in rows (360's) using the VR Drive 2.

Here's an example shot with that: http://08.ae/panos/SZM2/virtualtour.html

My question is this - if the banding is down to vignetting, why is it only horizontal?
