Sunlight and extreme panoramas

The photo above is an extreme panorama, it is stitched together from 9 portrait mode images of the Golden Gate Bridge.  This is the cropped version, and the actual image is 19,600 pixels wide. If I zoom in, I can actually read the speed limit signs, not well but I can. I don't know whether that actually qualifies as an extreme panorama in other peoples minds or not, but it is certainly larger than I have played with before.

The reason I took this photo was two-fold, I was wondering if I could actually see the shadow of the earth cross the Golden Gate Bridge.  Unfortunately, the horizon had clouds so the terminator line wasn't as clear as I had hoped.  This is the last series I took where the sunlight was actually shining on the bridge. 20 seconds later it was gone.

I might mention that processing this image took all of the memory in my computer and then some.  My machine isn't big, It only has 3 gig of memory available, and 4 cores. I am now running Windows 7 64-bit.  The upgrade was interesting, I lost the use of several devices. Apparently the 64-bit windows does not support Adaptec SCSI cards, which I have to use the Polaroid Sprintscan 4000 slide scanner.  Thankfully Linux comes to the rescue. I wasn't able to save my Wacom Intuos serial tablet, but I did get a new Wacom Bamboo tablet for Christmas.  It seems very nice, and for me easier to use.
