HDR Test

I was intrigued when I first heard about High Dynamic Range (HDR) photography, in part by the rich images, but also by the controversy it raises.
HDR images are composites from multiple exposures that draw out high- and low- lights in a single image. This produces a result that is nearer to what the human eye can perceive (as opposed to film or a camera sensor), but the result can look a little odd because we are not used to seeing this range in a photo.

So, I had to test this with my new camera...
...but Photoshop, my editing tool of choice, didn't support my Panasonic camera's RAW format! Dull.
However,  I knew a solution would present itself so I took some exposure bracketed images to use when I could.
A recent update to Adobe's Camera RAW software has answered my need, and I have finally managed to make my first HDR image:

HDR result 

Here you can see the three exposures that were merged:

Over exposed - bring out foreground / dark detail

Standard exposure

Under exposed - bring out highlights / sky detail
I am really pleased with the result.
This view from our holiday cottage in the Scottish Highlands was beautiful, but the light contrasts were so great that a single standard exposure just didn't do it justice.
I think this HDR image does a much better job.
What is your opinion?

You can find a good technical wiki article here, and some beautiful HDR images here.
