[HDR-photo] Starting out...

[Ferrell McCollough]

Royce,

I'm glad to hear your having good results. I'm now wondering if the 
uncropped pano's with outside transparency could be a problem.
Your images are spectacular, Canada is beautiful. Your a trooper to be in 
the cold shooting, brrrr......
I will also be looking into Panorama Factory,
Thank you,
Ferrell
