Taken from near The Strand in Galveston, Texas. The image underlying the rollover is after processing with Photomatix Pro, which you should always consider to be your starting point for post-processing when you are working with HDR images (i.e. never think of the image created by Photomatix as your final HDR image).
[Technical Note] This particular image had an alignment problem that Photomatix couldn't resolve (it was taken hand-held) so I aligned the images by loading them into Photoshop CS4 as three separate layers and then used the auto align feature, cropped the edges to lock in the alignment (basically trimming the uneven edges caused by the auto alignment process), and then saved each layer as my Photomatix input. This is a technique I credit to Larry Patrick from the Bay Area Photo Club and it really does a great job.
