You can change which parts of the original image receive most attention from the filter by hitting the ‘S’ key on the keyboard.
The rightmost slider is the edge & smoothing slider:
The simulation of smoothing in the thumbnail image is only approximate.
Manipulating the other three sliders you can emphasize parts of the image and de-emphasize others. The main three sliders control Hue, Saturation and Value (the HSV color system).
The areas closest in color to that which you see in the rectangle above the slider are the areas which have most force for the effect. Here are some common settings:
You can mix and match all sliders to give you the force field you find most pleasing. If you get lost simply hit the default button.
The invert check box is for reversing the effect of the force field, so if, with the sliders, you chose highly saturated areas, clicking invert would give more force (white areas) to the unsaturated area. An example of the use of the invert check box is changing mountains into lakes and lakes into mountains with the Relief Map effect .
To use the invert check box you must go into manual mode (switch off the "Wizard chooses" check boxes in the effect you are interested in) .
