Paso Robles Vineyard Sky Panorama
I photographed this same vineyard and tree about a year ago, just off Highway 156 between Paso Robles and Lost Hills, at a similar time of day. The scene was quite different, with the vines on the right already cut back. This time I had a 3/4 moon to work with and decided to go for the curves of the land. This is actually a nine shot vertical panoramic, so it is exceptionally sharp. The moon, though small, serves as a central anchor point for the rest of the image elements. Lots of little tweaks went into the final image but it was how I originally imagined it when shot. I must say that Photomerge in CS3 has made panoramics a snap and is VASTLY improved over CS2--just night and day improvement. Key is to set the camera on manual exposure and rather than shooting horizontals, shoot multiple verticals for greater resolution.
Something else to think about. By breaking an image down into segments and making separate shots and then stitching them later you create the equivalent of much higher resolution. No need to invest in a D3 or a PhaseOne back for a Hasselblad. Even a 6 megapixel D70 becomes a 10-12 megapixel camera when you stitch together to shots.
In response to another question: this was not shot with a true panormic head, though I did try to find the nodal point and level up the camera. With enough overlap I am finding that CS3 really nails the stitching (I stitch 16-bit images) and does an amazing job of correcting for aberrations caused by not keeping the camera perfectly level.
