OK, this shot consists of 10 HDR images which of those were three shots each for a total of 30 shots. I processed the HDR shots first then stitched together with PTgui and then fine tuned in Lightroom 3. The final high res image is a 16 bit tiff file with 557 megs of data. I was starting to choke down the computer finally with the main image but it still did it. Click on the original tab below the shot for best results.
