If you like playing with and helping to improve software via beta, check out the new Photomatix Pro V5 beta. If you are into HDR, you will like what they have done here. I think this will be a tremendous upgrade/update with new processing methods, better auto ghost removal, and other cool features. Check it out via the link below. Standard caveat, this is beta software so it is not perfect yet, but it is very, very good!
