Case of using manual profiling

As compared with automatic profiling, which produces a noise profile in one step, manual profiling is done in two sub-steps with two noise analyzers used. The Rough Analyzer is used to do initial analysis of image noise; it produces a rough noise profile. The Fine-Tuning Analyzer improves the initial analysis and produces a fine-tuned noise profile.

Both Rough Analyzer and Fine-Tuning Analyzer need uniform image areas to measure noise properties. If the image has uniform areas that contain noise without visible important image details, Neat Image can analyze the noise properties using these areas. During manual profiling, Neat Image does not automatically find these uniform areas (or areas that contain no details important to you), so you have to manually specify areas that it should analyze. A uniform area (with minor variation in all channels) may be overcast sky, clear sky (without clouds and birds), or any other part of an image with no visually perceptible details (except those caused by noise).
