A test of my D700 on the hotel deck: downtown Minneapolis. Camera set to Aperture priority mode, Auto WB, Auto ISO, AF Nikkor 85mm f/1.4 IF-D at f1.4. The photograph to the right is ISO 11200.
See additional photographs and the “More Properties” information on D700 high ISO Flickr set for additional details.
No post processing in Photoshop CS3 other than to resize for here. All noise reduction software applied at default setting.
I did not speak to the result intentionally, each should reach his own conclusion.
Added: Topaz Denoise then Nik Sharpener Pro 2.0 applied to the image.
Noise reduction applied to whole photograph added to the Flickr set here.
