Spherical panoramas with M8

I always thought that a fisheye lens was required to satisfactorily render straight lines and curvatures near the edges of the frame. I guess I am proven wrong.

Anyways, what program did you use to make the spherical image? And how on earth did you not get your feet in the picture?
 
How it works

How it works

Equipment: A stable tripod and panorama head specially machined for the M8 with the CV 12/5.6. (Mine comes from 360 Precision.) There is a tar file that shows the setup here: http://abdallah.hiof.no/M8-panhead.tar (Right-click to download.)

With the CV12/5.6 I take 1 picture straight up, 8 around at 30° up from the horizontal, 8 at 30° down and 2 straight down rotated 180° from each other to eliminate the "shade" of the side arm. A sequence of 19 pictures in all always starting from the same horizontal index point. The panhead has very precise click stops at 45° intervals horizontally and 60° vertically.

My feet are hidden behind the arm when taking the straight down images. The tripod and head can also be completely removed by patching in a vertical shot taken with the camera pointing down at arm's (or "tripod's") length and patching it into the bottom of the final "cube" with Photoshop.

AutoPano Pro was used to stitch each image into an equirectangular panorama and Cubic Converter to turn it into a spherical panorama which is rendered on the inside of a cube. PTMac is also a good, if somewhat more involved, stitcher. Both can be used to make a template to stitch many panoramas in batch, especially panoramas with expanses of featureless space like the sky, snow or very dark environments like this: http://abdallah.hiof.no/granbakken/20060903.html

Building a template to handle many panoramas needs a panhead which is precise enough to ensure that the camera is in the exact same positions every time with exactly the same angle and sequence between shots.

The larger (higher resolution) the panorama, and slower the computer, the more "jumpy" interactive turning the panorama with QuickTime. A few of these panos were fairly large. I.e. over 2-3 Mb.

Glad you enjoyed them. (We have more here: http://abdallah.hiof.no/kongeveien/ The first 2 rows were taken with an R-D1 and a CV 12/5.6, the rest with a 5D and 17-40/4 at 17mm.)
