Use your camera's noise profile or find it.

What camera did you use? Go to neatimage.com and download the profiles they make available and use that instead of a testing area.

The best way (as already pointed out) is to use noise profiles for the camera you use ... they can be downloadded from the Neatimage website ... alternatively, you can make them yourself.

 

Another way is to select the area (that neatimage uses to calibrate) yourself.

I think what he's saying is that there are no textureless portions of the image to calibrate on so manual selection isn't really useful. Like trying to white-balance an image that has no pure grays in it.

Jerry, as others already advised, you can probably download a profile for your brand and model of camera from NeatImage web site. Even better, make your own profile of your camera at 1600 ISO. You can use the target downloadable from Neat Image web site. To work best, the picture of the target should be taken at a similar light temperature than the pictures you want to fix, however even at a different light temperature it should give worthwhile results. If you can calibrate on a featureless area of the picture to be fixed so much better, otherwise, when your picture doesn't have it, you can do without it.

 

For the future, consider to bring with you a small print of NeatImage target (like 4x16in, or 10x15 cm), and when you use the camera at high ISO, also take a picture of the target (putting it out of focus) in the same light conditions.

-- "... so manual selection isn't really useful."

 

Short of a noise profile for the camera in use, the manual selection will still deliver a good startpoint (given the manual selection was done with care). Before one lets neatimage clean the image one can/should tweak the settings resulting from this selection.
