This was quick hand-held test of high ISO on the new Canon 5D Mark II. And it is a big of a disappointment. I know at 128,000 I pushed the exposure by seven stops which was huge. But there was more noise than I like. Higher than that there is a great deal of banding. Yesterday's shot at 500 ISO is very acceptable.
On the left half is the original image. On the right half I applied Imagenomic’s Noiseware.
