Open Source HDRI application

Initially, when I learned about High Dynamic Range Images, I looked at the HDRshop application, which was simple, but at the time more than welcome. I just found out about Qtpfsgui, which is an Open Source application to load bracketed images (with different exposure) and turn them into real HDR images. Cross-platform (Windows, Linux and OSX) and Open Source.
