Photomatix - review of HDR image creation software
"Classic situation: You are in a church with a beautiful stain-glass window. You want to take a photo but you realize you have to make a choice: you either take a slow exposure shot of the window, meaning that the rest of the image will be way underexposed, or you try to take a photo of the whole thing, leaving the window very overexposed, meaning you will not see any of the beauty of the window. What do you do? Well, normally you have to make a choice, because the sad reality of either film or digital cameras is that they have a very limited dynamic range. That's where Photomatix comes in and opens up a whole new world of photography for many of us who've tried in vein to get what is not possible otherwise. While this is a somewhat labor intensive process that includes a lot of post photography operations before you have your image, the end result is that you will get images that are simply not possible otherwise."
