Free HDR software for Windows

I was looking for free software that would run on Windows that would aid in creating HDR images.

After about 5 minutes of searching I came across these 2:

1. Luminance HDR (qtpfsgui) and

2. Picturenaut

I am new to HDR photography, so I wasn’t very sure about all the different options in the software. But I found it a lot more easier to create a cool looking HDR image using Luminance than with Picturenaut.

Here are the input images that I used (found via a Bing search for HDR source images)

This was the resulting image using Luminance:

More to follow, once I learn a little more about the 2 softwares and get a few sample source images of my own.
