Neat Image user guide / Filtration process details / Stage III. Adjust filter settings

Use preview when adjusting filter settings

To use preview, simply click (the Preview button). This will select an area in the image and automatically apply filtration to this area.

Or you can manually select any image area: press the left button, drag the mouse and then release the button. When an area is selected, Neat Image will (if auto recalculate preview is checked; see Filtration options) automatically apply filtration to the selected image area. You can also manually invoke preview recalculation with the Preview button, or the Filter | Preview menu item, or the F5 hotkey.

As soon as the preview is ready, you can left-click on the selected area to temporarily switch back to the original image for comparison.
