Very nice Bob

[Andy Perrin]

Nice houses.

[Nate]

Excellent wide shots!

[bobfriedman]

my thought is that I was too close... gave too distorted a perspective when the spherical pano was projected onto the 2-d plane

Bob, what is up with the faint cloud swirls? Is that a projection side-effect?

so this is a combination of water vapor and lens flare similar to hot spotting. spherical panos require lens angles that will stress even the most robust lens (the 17-35/2.8 was never designed for IR), the uncoated RG850 filter doesn't help either. the reason that they appear as swirls is that this is a spherical image projected onto a 2d plane (equirectangular projection) which produces an additional artificial curvature.

very striking. I noticed the distortion right away, but average non photographer probably  wouldnt' know.
