Hermit Thrush shot in very low light with my new Canon 7D. This image is under-exposed about 4 stops at ISO 3200 on the camera, with an actual exposure index of about ISO 51,200. I did my own style of NR using photoshop basic tools - "dust and scratches" to get rid of warm/hot pixels, and surface blur on a+b channels in Lab mode before downsampling, and sharpening of L channel, after downsampling.
