This is the same image, reduced in size to match exactly the Alpha 700 dimensions. It provides a direct comparison with Alpha 700 ISO 6400 performance, and also with any other 12 megapixel camera such as the D3/D700. For a direct comparison of noise size - identical processing parameters, same -1 ACR compensation, almost the same light level (1/1600th at f4, 1/3rd of a stop lower actual light value present) see http://www.pbase.com/davidkilpatrick/image/103705532.
