I just redid a sunrise 360 degrees fully immersive panorama I made at Emerald Lake. I combined multiple sets sets of exposures for this result. The old version had the sunlit area blown out.
I turned this into a nice QTVR too, but I don;t have a good place to host that yet. I'll post it when I do. When I took these photos, I hiked up from the trailhead far before sunrise. Always fun, especially when it is snowy and icy ;-). For these 360 degree panoramas, I use the awesome 10.5 mm fisheye and a homebuilt device that can be seen here:
I stitch using the awesome open source/freeware hugin using enblend.
