This is just a crop of a large panoramic image (which is available here).
I’ve been meaning to process this one for a while, but my old PC wouldn’t have been able to handle it. The new iMac has outdone itself with this post-processing behemoth. 7 Raw images converted to 21 TIFFs (each 23MB in size), merged into 7 HDR TIFFS, combined into a panorama (by hand…).
Not sure about the black/white conversion though – I’d be interested to hear comments
