clean hdr images?...the two dont go together in my opinion...you loose a lot of image quality with hdr...cs2 hdr merge is not that great either...(or at least the tone mapping is'nt)....use cs2 to blend the images then get the photomatix plug in to do the tone mapping...this si supposedly the best way.
hdr mesess with the colours a lot so you need to do a lot of colour correction...you also loose sharpness...
The colours are all so vivid, especially the contrast between earth and straw. I also like the line play. The sky to the left looks as though there is a storm rolling in from the sea about to wash away the sunshine bathing the land. Another outstanding shot!
I must say, you have some very neat farmers down your way, the ones up here just seem to make a mess!
