Here are two photos from the same location, the first is in a portrait orientation the second in a landscape orientation. Both are HDR images taken from a selection of 5 Raw files from the Nikon D300 and shot with the Tokina lens the 11-16mm f2.8. The photos were then edited in the HDR software called Photomatix and the bottom one was then also cropped a little in Adobe Lightroom and had its blacks and lightfill pumped up.
After the break I shall add one of the original photos that this photo was created from for you to see how the dynamic range is increased with HDR editing.
