I had no problems making panoramas with Autopano Giga. That was easy. Took me the same 5 minutes to figure out as PTGUI and no need for the documentation either.
My week with the documentation was in getting the HDR output to work, which now seems to NOT actually work. I had to exhaust every possibility that I just couldn't figure out the software. I never have given anyone reason to say to me, "RTFM!" nor do I ever want to. (You're welcome.)
So Hans, please have your 62 year photographer explain to me just how a 32 bit HDR image with no pixel RGB values above 1 is actually a representation of the photon energy present in any HDR panorama not taken in a dark closet.
That is where this thread started. Not with stitching (which I already pointed out, my PTGUI first attempt rendered all manner of minor stitching errors), but with Autopano Giga's "HDR" actually being LDR wrapped in a 32 bit file format with no RGB values above 1.
So far, in this forum, no one has addressed the issue first brought up months ago (not even by me--I didn't even start this thread) which is, where does the highlight detail go? It should be there in the .hdr or .exr, in values above what your monitor/graphics card can represent but recoverable in software as simple and ubiquitous as Photoshop. Instead, various other red-herring issues from tone mapping to how the images get fused to workflow have been brought up. I won't lie; It has been a bit frustrating.
Maybe, if anyone here wants to investigate this other potential application for Autopano Giga, beyond simply stitching LDR panoramas, (if the HDR throughput actually ever gets fixed or If someone can point out my stupidity in not being able to figure it out), go ahead and spend some time here: http://www.hdrshop.com
That piece of software, HDR Shop, actually handles 32 bit floating point HDRI they way it should actually work--the way this guy, http://www.pauldebevec.com
, (whom I casually know, by the way) designed and invented it.
Meanwhile, If anyone wants to compare my HDRI output directly from both Autopano Giga and from PTGUI, have at 'em.http://mattmerk.com/HDRItest/
