panoramic HDR output not working, driving me insane

[Aaron F. Ross]

Hi,

I know better than to expect something for nothing, but this application is driving me insane.

I import some HDR files, lay them out and they are more or less fine.

I try to export through the Stitcher, and low dynamic range output is sort of working, except the hottest parts of the image are massively clipped off. I don't know how to fix this. I tried running the photometric optimizer, but that didn't help.

But much, much worse, when I try to create an HDR panorama, I only get one of the five images. No stitching takes place.

The Stitcher throws up a log window with a bunch of information, but it goes by so fast that there is no possible way anyone could read it. I looked for a log file but couldn't find it.

So basically, this program is inscrutable, and doesn't function as expected. Maybe someone can tell me what goat I have to sacrifice to make this damn thing work.

Otherwise, point me at a commercial application that will import some HDRs, stitch them together, and output an HDR panorama.

Thanks

Aaron

Can I ask, are these full floating-point HDR images or tonemapped output from HDR images?

Hugin can stitch full HDR images into HDR panoramas, but it can't convert them to LDR panoramas at the same time - For this you need a separate tonemapping tool (like luminancehdr).

If you are stitching tonemapped HDR images (actually LDR data) then you have to disable or reset all Hugin photometric optimisation, as this can only ever create weird results.

Hugin can save a log file, otherwise are you able to upload some test images somewhere?

Sorry it took me so long to get back to this.

These are 32-bit .HDR documents.

Where is this secretive log file?

In the end, I told Hugin to save the intermediate files, which turned out to be 32-bit TIFs. I took those into Photoshop and lined them up manually. Such a pain.

I uploaded the .HDR documents here if you want to test them. These are all fisheye photos with a 178 degree field of view.
