One of the things I like about Photomatix is the ability to create pseudo HDR images. This means you can use a single exposure with Photomatix, and the Tone Mapping filter. This doesn't represent an image the the full dynamic range of multiple exposures, but it can work beautifully for a single HDR effect. This is very helpful if you any type of movement throughout the composition, such as cars or people.
This was a test shot, I came back in the evening to shoot at twilight, but I liked this single image. I used Photomatix to process the image as an HDR. and used the Tone Mapping filter for a more colorful effect. A single layer of texture adds a little more depth and drama to the image.

PS... Like the HDR look? You'll learn about this and more in my Photoshop - Enhancing Images and Creating Works of Art course, online at BetterPhoto starting on June 9th. I hope to see you there!
