Re: [!! SPAM] RE: OT: Fisheye for HDRI capture

[Sam Cuttriss <cuttriss(at)whiskytree.com>]

d300 auto bracketing and nikon 10.5mm, via ptgui. ive only just got it 
all set up, but it looks very promising.
i dont think its worth trying to get a full 180, especially with the 
sigma, a large proportion of the image is really soft and chromatic 
aberration is significant.
