Nice! I've seen a Flikr collection of these type of images before. Would
very much like to know how you accomplished it.
That one is the third one I've made, all since Thursday. So there may
well be more different approaches than I know about.
The classic way to do this is to start from a full-circle panorama.
That's not what I'm doing, though.
I'm taking a partial panorama, resampling it into a square, turning it
upside down, and applying the polar coordinates filter to it. This
leaves a visible seam where the two ends are brought together, which I
then manually retouch out. I also have to do some fill work on the
corners, but that's usually simple (the seam is NOT always simple).
They tend to look better with a blue sky, but the sky wasn't blue where
we were shooting on Thursday. Shooting with the horizon line lower than
usual, and with a few interesting things sticking up severely above it,
contributes to the effect; the one I put in the gallery this week is the
most extreme case of that of the ones I've played with so far.
They're sometimes called "micro planets". Googling turned up multiple
descriptions and videos of how to do it, if you want more detail than
the above. I just learned the technique Thursday morning, in
preparation for a photo expedition (I've seen several of these I liked
recently, so I wanted to play with them myself).
I thought I sent it along as notes, but I seem not to have, so I should
mention that that photo is of a sculpture called Johnny Appleseed by
Mark di Suvero, and it's at the Franconia Sculpture Park in Franconia MN.
