I apologize to the Mac community at large here at Renderosity. At current there is no Mac version for HDRShop, and I make no claims to know any other software that will do what this one does. There has been some discussion of Virutal PC use with HDRShop as there is only the one executable file, but I cannot vouch for that. Grav, the tutorial in the thread only works for PC (right now at any rate), but the 2nd exercise is using a Bryce panorama, so, yes, it can be done... but only by a PC... :( Mateo, HDRShop does more than convert from just a spherized panorama, but that it can do. It can take a 6 face-image and create the sphere or standard panorama from it. The attached images were all created from the bottom panorama. Ken
