QtPfsGUI (qtpfsgui.sourceforge.net) is a graphical interface based on another open source project, that gives you the power to experiment with HDR imaging.

The last two versions are a great improvement over the previous one, with the introduction of anti-ghosting, alignment and a new operator (Mantiuk).

I started employing it six months ago (you can view from my early attempts in my qtpfsgui set on Flickr).

Now I think it's a very mature (even if very complex) application and I start to obtain almost realistic results, similar and sometimes better than what I can obtain from Photomatix).

Let me now if you use it and what are your impressions.

Some samples:
