I recently upgraded to NIK Software's HDR Efex Pro 2. I understand over-the-top HDR images may turn you off, but I would recommend everyone at least download a free trial, watch their training videos and give it a spin. I use it to compensate for my camera's weaknesses to make my images look much more like what I saw with my eyes. The new alignment feature allows me to take hand held shots. Also using the amazing ghost removal feature I have taken shots with moving traffic that you could not tell were not a single image!
This new version gives you such great subtle control that you can get very natural looking images. In a great many cases it has given me far better results than I could have ever gotten from manipulating a single RAW exposure.
Until sensor technology improves I will be using HDR Efex Pro 2 a lot!
