Panomatic is impressive. Thanks for the tip! I had to increase
sieve1 from 10 to 20, but then it found 28 controls points and all of
them appear to be good.
I'm not sure my hdr problem is about tonemapping. The remapped images
produced by nona really don't look like hdr. When I look at the
original hdr and vary the exposure, the sun grows from a tiny bright
point to washing out the entire sky. When I remap the hdr using nona
and do the same, the sun is washing out the entire sky and varying the
exposure dims/brightens the whole image. It seems my problem may be
with nona.
I notice that nona produces 2 files for every remapped image, ".exr"
and ".gray.pgm". For the record, I'm looking at the .exr. I don't
know how to use the .gray.ppm.
