HDRSoft have released version 5 of their Photomatix products. I have owned v4 Pro for sometime now and to my delight the upgrade to version 5 was free. I only noticed that the new version was available this morning so apart from downloading, installing the software and checking it runs OK I have not had time to use it yet.
You can find more information and download the upgrade from HDR’s website here.
Happy HDRing 🙂
