My first 360

360o panorama, that is. This was taken from the top of Thorpe Cloud in Dovedale on Saturday afternoon, and as usual it was put together with autostitch.

I broke my usual rules with this, taking all the shots handheld (I wasn't about to lug a tripod up there) and left the camera on auto (I was in a hurry), but the result is not too bad. Of course it suffers from the usual autostitch curved horizon, and you can see areas where the exposure varies a bit too much. There are 17 individual pictures stitched together for this shot.

Because it is a 360o pano, and because autostitch is completely automatic, I had no idea where it would start and stop. As it turns out, the first shot I took has ended up in the middle. That's where the "ghost" is – somebody who was standing on the peak when I took the first shot but who had gone by the time I got back there after taking all the others. I'll edit that out sometime.

Thorpe Cloud is 930' about sea level (GPS height) and about a 450' climb.

    Great picture!!

    The ghostly figure roughly in the centre of the image is a bit disconcerting, I'm assuming this is a glimpse into how Autostitch puts things together and not some paranormal phenomenon!! ;)

    Yes, if there's something different between two versions of an overlap the blending process will produce something between the two, hence the ghost. That spot in the middle was the first picture I took, and there was somebody standing there at the time. By the time I had worked my way all the way around and got back to the same spot, they'd gone. I can use one or other of the originals to paste over this spot in the pano to either reinstate them properly or reomve them completely. I haven't yet decided which – I need to try both and see which I prefer.

    Incidentally, the individual pieces of this pano were taken in portrait orientation to provide some extra height and vertical resolution. If you follow the link to the full-sized picture and view it at 100%, the level of detail is quite impressive!

    I'm still looking for an genuine opportunity to produce a 2-D panorama with lots and lots of pixels. This one is a little over 40MP. There's got to be a 100MP picture out there waiting to be taken…:-)
