[HDRI] Photosphere 1.6 available

[Kirk Thibault]

Hey folks - I had some LDR fun with the panoramic stitching features  
recently added to Photosphere.  See:

It is interesting to play around with choosing the pano orig and pano  
dest points under various circumstances.  It is interesting to see  
how Photosphere fuses the images, especially when there are distinct  
foreground and background elements with various levels of distortion  
due to focal length.  I was using a cheap little foldup tripod.  I  
found that it is probably worthwhile to get a tripod with a level so  
you don't get a tilt angle and have to crop up significant amounts of  
the image.  I will probably also look into the panoramic tripod  
attachments that permit panning about the lens nodal point.  Cool  
stuff.  I am pleased with it so far - I will probably try to recreate  
the same panos in PSCS2 and see how they work out for comparison.
