The good thing on the other hand with Photomatix is that you can also render HDR images (not really HDR tho) with a single jpg file...if ur intrested i could share how to, a freind of mine tought me how to do this.. here it goes. The author name is Ed or Photoj the review can be read on cameralabs.com

Step 1: Save your image as a 16bit TIFF - to do this with CS3, go under Image > Mode > 16bit.
Import your 16bit TIFF into Photomatix. Select Automate and Single Batch Processing and convert the TIFF into a Radiance RGBE. This generates a new HDR file.
Open the HDR file in Photomatix under HDR > Large File Processing, and then hit preview. This shows your HDR. Select preview size to 1024 for a larger working space. Your screen should look like this:

You can compare it with your version of the HDR on the screenshot - I did this with my secondary monitor on as well - the extra workspace really helps on editing. (You can just about make out my ballroom photos on the right monitor from the weekend that I was working on before doing this mini-walk-through).
Now back to the HDR - we will stick to the Details Enhancer. Here you can play around with your settings. Once you're happy with what you see, then save as a TIFF and go back to your photoediting software.
Here is the Tone Mapped HDR I finished and saved as a TIFF in Photomatix:
