Filters

1 Filter List
The list of filters shows all filters found in the currently selected category. After clicking on a filter, you can use the up and down arrows to navigate to the next or previous filter displayed.

2 Categories
The Categories enable you to filter the provided filters. Clicking on a category will show only those filters that are found within that category. Click on the All category to show all filters again.

3 Favorite Selector
Clicking on the star next to a filter allows you to select it as a favorite filter. Favorite filters will appear within the Favorites Category as well as within the Nik Collection Selective Tool, if using the software through Photoshop or Photoshop Elements. To deselect a filter as a favorite, click on its star again.

4 Filter Presets
Rolling over a filter name displays the Preset button. Clicking on the Preset button will show the available presets for that filter. Presets in Color Efex Pro 4 show the range of possibilities found for a particular filter. Unlike in other Nik Collection products, you cannot create or import custom presets. To save one or more filters with custom settings, click the Save Recipe button to create a custom recipe.

5 Filter Twirler
Clicking on the filter twirler displays the filter controls.

6 Toggle Filter
Toggling this checkbox on and off shows and hides the filter’s effect on your photo.

9 Filter-specific Controls
The sliders provided vary for each filter. For more information on sliders within each filter, please see here.

10 Control Point Section Twirler
Click on the Control Point Section twirler to display the controls available for control points.

11 Add + (100%) Control Point
To add a + Control point, click on the + button, and then click on the image where you wish to place the control point. Clicking the + control point button automatically sets the Base File slider to 0%, making it possible to add the current filter effect only to the area selected by the control point, and places a control point with the Opacity slider set to 100%.

12 Add – (0%) Control Point
To add a - Control point, click on the - button, and then click on the image where you wish to place the control point. Clicking the – control point button leaves the Base File slider at its current value and places a control point with the Opacity slider set to 0%, removing the filter effect from the selected area.

Adjusting Control Points

A Size Slider
The Size slider affects the reach of the control point. By increasing this slider, you can affect objects similar to the object that the control point has been placed upon but that are farther away from the control point. When set to 100%, the control point no longer bases its effect on the location of objects within the image, instead relying solely upon the color, tonality, and texture of the objects to determine whether or not to affect them. Decreasing this slider will make the control point affect only similar objects closer to the control point.

B Opacity Slider
The control point's Opacity slider controls to what degree the current filter effect should be applied to the selected area. A value of 100% ensures that the current filter effect will be fully applied to the selected area. A value of 0% prevents the current filter effect from being applied to the selected area. The + and – options for adding a control point set the starting position of the Opacity slider, however the Opacity slider can be adjusted after the control point is added.

13 Opacity Slider
The Opacity slider makes it possible to control the overall opacity of the current filter. The Opacity slider is automatically adjusted to 0% when using a + (100%) control point, but can also be adjusted manually.

14 Show Effect Preview
After adding a control point to the image, the checkbox within the Show Effect Preview Column will be enabled. By un-checking this box, you can disable that control point’s effect on the image. Click on the Show Effect Preview Column header to show or hide all control points' effects.

15 Size Column
The Size Column will display the value of each control point’s Size slider.

16 Show Selection Column
The Show Selection Column enables you to show the selection of a control point. Checking the box next to a control point in the Show Selection Column will show only the selected control point’s selection. The control point is affecting areas inked in white, while areas inked in black are not being affected, with gray areas being partially affected. Click on the Show Selection Column header to show or hide the selection of all control points.

17 Group Button
Click on this button after selecting more than one control point to place the selected control points into a group. All control points that are added into a group will obtain the same enhancement slider settings. Groups act in a similar fashion to control points, except where a control point bases its selection off of a single color and tonal value, groups can use multiple values to create a more precise selection. A group of control points share a single set of enhancement sliders and apply the same enhancement effect to their selected objects.

After adding control points into a group, the icon for the control points will change, with the enhancement sliders being presented only on one control point. The size slider for each control point in a group however can be adjusted independently.

18 Ungroup Button
To remove all control points from a group, select the group and then press the Ungroup button. All control points will be displayed as ungrouped, allowing you to delete, modify, or create new groups from the individual control points.

19 Duplicate Button
Clicking on the Duplicate button will duplicate the currently selected control point(s).

20 Delete Button
Clicking on the Delete button will delete the currently selected control point(s).

21 Add Filter
Click this button to add a new blank filter that can then be filled with one of the filters from the Filter list. This makes it possible to stack additional filters on your photo. To add an additional new filter without having to first click this button, hold the Shift key while selecting a filter from the Filter list.
