Re: hdr, photomatix and photoshop

Ok. Forget about Photoshop then.

produces the best results. Output for me is for web so I dont care
about creating any hdr file, I just need the tonemapped results. Is
it true, would you say then that exposure fusion is better as used
by PTGUI pro. Manybe that would be the best option for me then as
workflow with ptgui (3.7) and photomatix is terrible. Ill download
the trial and see for myself.
As regards the colour temperature thing it's not a white balance
issue as the images I'm using all have correct white balances for
outsides and insides on the original raw files. They only go orange
after tonemapping. Ill try the desaturation thing. That's obvious
Thanks for the advice

PTGui uses exposure fusion on the result panoramas, which is time

the tendency to increase saturation (sometimes in a strange way).
Exposure fusion won't do that, it is a very sophisticated way of
exposure blending which uses the best exposed parts of each image.
Hence there should be no change in saturation. But actually it is a
white balance issue, intensified by tonemapping.
