If this option is selected then Neat Image will look for matching noise profiles in the folder which you can specify below. This should be the topmost folder of all the subfolders with noise profiles to be checked during automatic matching.
By default, the PROFILES subfolder of Neat Image installation folder is used.
If this option is selected then Neat Image will look for matching profiles in the folders of the input images. If you put desired noise profile to a folder with input images and select this option then Neat Image will select this profile for every image from that folder. If there are several profiles in such a folder then the best matching will be selected for every input image.
To automatically match profiles for the input image, Neat Image compares the device parameters of the input image and candidate profiles selected from folder specified by the above options. Different parameters usually have to be matched with different priority. Using Matching parameters priorities controls, you can select the priorities of such parameters as Input device, ISO rate, Compression, Resolution, Sharpness, Exposure:
- Match - the parameter should match exactly;
- High - it is highly important that the parameter is very close or matches exactly;
- Low - it is preferable that the parameter is close or matches exactly;
- Ignore - the parameter is not important at all.
If this option is checked and Preset Matching is invoked then Neat Image looks for a filter preset in the folder of used noise profile.
By arranging profiles and presets pair-wise in several folders you can customize noise reduction as finely as you wish. For example, you can have several profiles for High Quality JPEG images in one folder and several more profiles for Normal Quality JPEG images in another folder. If you put two different filter presets in these two folders (one preset for High Quality JPEG and one for Normal Quality JPEG in corresponding folders) then Neat Image will automatically load one of these two presets according to currently used profile: if a profile from the High Quality JPEG folder is used then a filter preset from the same folder is loaded.
In the folder of used profile, Neat Image looks for a filter preset that has the same file name as currently used noise profile. If there is no such preset then Neat Image selects the first found preset in this folder.
If this option is checked then Neat Image is following preset matching rules specified in the table that can be opened using the Configure button.
The Preset Matching Rules table may contain several rows, where every row represents one matching rule. You can create, edit, re-order and delete matching rules in the table.
Click the New rule button to create a new rule. In the Matching Rule popup window specify (1) the relation between the ISO rate of the input image and the ISO rate of the rule, (2) the ISO rate of the rule, (3) the filter preset to be used if the condition specified by this rule is satisfied. When all three data elements of the rule are filled out you can put this new rule to the table using the OK button.
To not filter certain images (for example, with ISO < 100) create a rule with the “No filtration” filter preset supplied with the software along with other presets available in PRESETS subfolder.
If the table contains several rules then Neat Image is consequently tries each of them from top to bottom. The input image’s ISO rate is related to the ISO rate specified in each rule and once the condition specified in the rule’s relation is satisfied Neat Image stop trying and picks up the filter preset from that rule.
Use the Edit rule button to adjust selected rule; the Up and Down buttons to re-order rules in the table; the Delete rule button to remove selected rule(s) from the table.
To complete changes click the Close button. Neat Image will automatically save the table.
