Here's three bracketed shots for anyone who wants to have a go at merging. If you do, could you mention what software you used and what steps you took (i.e. post-merge editing, whether you used de-ghosting or not etc).
PS - I'd recommend aligning the images during merging. The camera was tripod-mounted, but it was a blustery sort of day.
JPG here, DNG to follow.
Here is one possibility. Used NIK's HDR Efex Pro 2. Started in Lightroom, then exported to HDR Efex pro 2, then back to Lightroom to fine tune and to make sure it wasn't overcooked.
Once it was uploaded, it looked too dark. Went back and increased the brightness which is the 2nd image.
