Per request, here's a quick example of an hdr done through CS5. This is actually only a combination of two images. One nice feature that photomatix lacks is that you can choose which exposures you're using while you edit. So, I started with 3, but clicked the hot one off. CS5 offers a nice set of presets, but offers fewer parameters for adjusting your image. The first image is obviously the middle exposure, uncropped.
