No Badger, the EXR that Terragen 2 has always been able to output is actually much better than "bracketed photos", it contains all the regular image data you'd need to output a tone mapped "HDR" processed image. The new render elements actually split up the rendering process and outputs different parts into totally separate images. So you get the atmosphere separate from the terrain, for example. So for just a very simple example, let's say you wanted the terrain to be more colorful and saturated, but not affect the sky; rather than try to use a selection tool, color selection, or other masking approach in Photoshop to select only the area you wanted to edit on the terrain, you could just load up the terrain and sky elements separately, make your modifications on the terrain element without affecting the sky element, then combine.
