The camera was clearly mounted on the edge of the crater, and pivoted through 360 degrees. Unless someone was holding up a mirror, the camera can't photograph itself. The technique would be to take a series of overlapping frames, and then stitch them together. You did not go full up and down. From what i gather many frames were shot to get shots. Ther is NO view of the picture left untaken. Aparently the camera was moved and then more fill in shots were stitched together. It as if the camera is floating in mid air. Nothing below it, nothing above it. greg |

It is a most remarkable image! --DR |

Ideally you just plant a tripod with skinny legs and a pano head and take a full circle. In a cave you really need the tripod. But on a mountain in full daylight, you can fake it if you are careful and the top is big enough and flat enough that you don't risk falling off. You just rotate yourself around, moving your feet so that the center of the lens never moves, and take the circle. If you fake it, the near points on the ground won't fit perfectly and you will need to use Photoshop's clone or "area fake" tools to make the dirt look right. If the final pano does look straight down, you will need either adjustable scaffolding or the fake method and LOTS of work in Photoshop. Straight up, outdoors, is easy: if the clouds move between shots, use Photoshop's "liquify" to make them fit. Doug |

Doug I think combining a Gigapan system with some CS5 editing would be the most seamless way of doing this. However what has been done with this image seems to be a lot more sophisticated than just doing the standard, moving in a circle to make the capture. http://www.gigapansystems.com/ -- Regards, Savageduck |

Even rote-beginners know how to do this. Why it befuddles all of you is beyond me. No, wait. It makes perfect sense. Because NONE of you have even the most very basic of panorama creating principles in your backgrounds. Hell, you can't even take a decent crapshot with your cameras. I shouldn't be surprised. Go ahead ... spew some more beginner's advice like an x-spurt. |
