HDR is the process of combining multiple photos with the hope that the resulting image is clear in both the light and dark areas. Getting good free HDR software that is capable of merging the photos together can be a little tricky since there are a lot of things it has to take into account, such as perfectly aligning each image.
Picturenaut is a free HDR app for Windows that has done a wonderful job with my photos. The program has been in the works for over 4 years, and you can tell that a lot of sweat has been put into making it. Merging your images will generally take just a few seconds, and with the settings available you are able to tweak the resulting photo to look exactly how you want it to.
Here are some of the high-level features offered by Picturenaut:
