i am a photomatix owner.
but to be honest i don´t use it anymore.
it was good but it´s a bit outdated yet.
the software has made no real progress for some time.
not when it comes to image quality.
i have send them some example images that had strange artifacts when processed with photomatix.
after a some debate about what causes the problem, i told them that other programs don´t show these artifacts.
they seemed not eager to solve the problem.
instead, after 3 or 4 emails, they offered me a refund and the advice to use the other program if i like it more.
