High Dynamic Range photo software - Merge of exposures and Tone Mapping of HDR images

Even the best exposure can have washed out areas, or areas of deep shadow. In most cases, you can't avoid this - you just get the best exposure you can.

In others, however, you have a bit more flexibility - in those cases, if your camera supports it, you take a range of images (generally 3 or more) - one perfectly exposed, then more on either side - some over exposed, some under exposed. Then you blend the photos together, in theory making one image with a very wide range of exposure within it.

All well and good - but that can be a lot of hard photoshop work.

So, that's where this software comes in - it does the blending for you, you just provide the images.

There's a free trial available, but the software is a little expensive (in my opinion) for a one trick pony at $99.

Available for both Windows and OS X.

So - anyone know how if a Nikon D70 can do auto-exposure bracketing?
