Hi Claus! I am not optimistic about capturing sky and sun using a simple camera. Without worrying about hdr codes - unless you achieve an exposure quick enough to have a non-saturated sun image, the hdr code cannot do the magic and invent pixel values. You may try low-transmission filters, but that costs you the weaker sky luminances. So probably, hardware needed.
Creating hdr images from ldr stacks definitely works without a Mac. Hdrgen and pfstools are just two of the many options available. Cheers, Lars. -- Dipl.-Ing. Architect Lars O.
