Stage II. Documenting the noise profile

At this point of building the noise profile for your camera or scanner, the noise analysis is done and all important noise characteristics are gathered in the profile. However, you may still have to manually document the profile if Neat Image has not done this automatically. With most images from digital cameras, Neat Image is able to automatically extract the crucial information about camera shooting mode from the EXIF data fields of the analyzed image and put this information into the Device name and Device mode fields of the profile.

If Neat Image has not automatically placed any information to the Device name and Device mode fields after noise analysis, fill out these fields manually.

• Use the Device name and Device mode fields on the Device Noise Profile panel.
  
  Here, you can specify the model of the image acquisition device, like "Olympus C5050Z", and describe the device mode. Specify parameters used to capture the image. For example, this can be something like the following:

ISO: 200
Compression: 5 bits/pixel
Exposure time: 1/80s
White balance: Default

About Device name and Device mode notes

It is highly recommended to specify these details to keep record of devices, device modes, and corresponding device noise profiles that you use. The noise characteristics of any two devices can be extremely different. Even a single device in different modes can produce significantly different noise. Therefore, it is always better to use separate noise profiles for different devices and device modes to avoid inaccurate filtration and artifacts. Commenting on the device name and device mode parameters helps you keep track of them when you do manual profile matching, i.e., when you manually select a suitable profile to process an image. Automatic profile matching available in Neat Image uses the EXIF data of the image files, not the Device name and Device mode fields, so filling out these fields may not be necessary for automatic profile matching. However, filling out these fields is highly advisable both for the clarity purposes and for the cases of EXIF-less input images (in such cases, you have to manually select a suitable profile based on the Device name and Device mode fields). Please see the Preparing a profile set for different device modes section to find more details about camera and scanner parameters that may need to be documented in the Device mode field.
