HDRI

I've been looking into Image Based Lighting for 3D animation and have been exploring HDR images.
I recently bought the book HDRI hand book (well worth the 20 quid) and have been applying the techniques in there.

Here is a shot of the London underground.

I know, boring shot, but it's all about technique. The method is to capture a range of images with different exposures and then combine them into one image. As you can see, there is a high dynamic range of light. Campare this with the source images and you will notice how much detail can be seen in one image.
And here are the source images....
