Some of these looked great. Also got some 4k video on youtube. See what you think. Some of the timing needs fixed in PS. But their not too bad. The entire trip is 12 mins so I have 1300+ frames for that, the #4 Photosynth I'm linked to is 1/10 the frames so we a entire trip. It seems like 2 frames a second is too much for Photosynth when it's so open. Check out #2-4 photosynths which have some mess ups.
