I haven't done much HDR work in the past few months but I gave it a try on a recent trip to the Lake District where it rained constantly.
This shot is of Ashness Bridge near Derwent Water. The usual angle is shot from the other side of the bridge but as it was raining so hard the place was mostly deserted and you could walk around looking for new compositions.
This is three images blended in Photomatix. The images were converted from RAW to TIFF files and desaturated prior to blending and tone mapping. Interestingly I added the slight sepia tint in Photomatix by upping the colour temperature setting to 2 and then played around with the highlight and shaddow saturation until I achieved this look.
I don't think its bad considering I don't usually like HDR Landscapes.
