Purest Feeling IR HDR

Well I finally done it, my first Infrared HDR. I just need to do a few more test to work on the sharpness but I have the process now. The process was just as gilad said, its the same process as any other HDR. This is a 5 shot HDR combined in Photomatix Pro and layer adjusted in Photoshop CS2 with a twist of color switching (something I don't normally do). If you would like to compare the non-HDR to this one here is the link [link]
