HDR Image - The process is called OOB - Out of Bounds. The technique is very easy. There is a Flickr site I belong to called OOB creations, here is the website. www.flickr.com/groups/oob/ There are step by step instructions on how to make this effect work. Once you get the hang of a couple of first time images, you will begin to experiment with different "looks". The Flickr group has many talented folks. If anyone is interested here is a link for photoshop users.
