I use Photomatix Pro for my HDR, but I'm not a fan of it. Not everyone does it right and I don't like hopping on the bandwagon just like LS1Tech did where everyone and their mother was trying it.

Oh man.. when LS1 Tech started doing it, I was pissed. 90% of 'em just looked like absolute CRAP.. it was embarrassing and gave HDR's a bad name over there.
