This is a favorite of mine from May 2007. It has been processed several different ways. Some of the renderings got a little (or a lot of) help from Photoshop plugins, some are more or less experimental, but stand on their own.
This one involved the creation of three "virtual exposures" from a single raw file that were taken into NIK HDR Efex Pro 2 and processed in order to bring out sky and other details. It's been a long time, but I think there might have been some color lookup tables, or the colors might have been the result of Lightroom adjustments to the resulting TIFF file.
In any case, this is probably my favorite of all the different processes I tried. It's been posted before, but not in a form that is useful for my England collection.
