Interface

This page looks at the common elements of the Nik Collection interface. Individual features are presented in the relevant plugin chapters.

Note that Nik Perspective has a different interface, which is outlined in full in the chapter about it.

Overview

Common interface (e.g. in Nik Color Efex).

The Nik Collection interface is composed of the following elements:

  1. The bottom toolbar
  2. The upper toolbar
  3. Image display area
  4. Left panel (Filters and Presets)
  5. The right panel (tools)
  6. Lower bar (plugin version)
Mac/PC menu bar.

In the plugin version, the menu bar at the top of the window contains the following elements:

In standalone mode, the menu bar includes the following elements:

The upper toolbar

The upper toolbar includes the display, comparison, and zoom tools.

The Compare buttons let you compare your image before and after correction:

Comparison display mode: Alternate
Split display mode.
Side by side display mode.

Zoom +/Zoom -: use to change the scale of the image displayed:

You can also press the spacebar to zoom in; release the spacebar to zoom back out. In this case, the Spacebar switches between the selected zoom level and the Fit to screen mode.

Fit/Fill display mode.
Zoom and browse window.

When zooming in on the image (including in Fill screen mode), a floating navigation window is anchored in the top right corner of the image display area (you cannot move it). You can move around the floating navigation preview window by grabbing the tile or clicking in it.

The image display area (plugin and standalone modes)

This is where the image is displayed, on a medium gray background, which you can change in the Settings.

Below the image you will find the following information:

  1. If you have opened several images, a floating scrollbar lets you switch between them.
  2. File name and extension. If the image has EXIF metadata, the shooting and equipment settings will also be displayed.
  3. You will also see the non-destructive changes check box and the Convert to Dynamic object check box, if the plugin was opened from Photoshop.

In the standalone version, if no image is open, the display area lets you drag images into it:

The left panel

The size of the left panel is not adjustable but you can hide or unhide it in different ways:

The content of the left panel varies according to the plugin and its filters and settings, but there are common palettes and functions:

  1. Custom
  2. Imported
  3. Last Edits
  4. History
  5. Instant Help
  6. Filtering by Favorites and Recently Used
  7. Search field
Common components of the left panel (e.g. in Nik Analog Efex).

Nik Viveza

To hide or unhide the content of a section, click on the chevron on the right. The figure indicates the number of filters or presets in each section and, depending on the section, you can use the double arrow to save, import or export a filter or preset.

The Custom section is used to create your own filters and presets. In the Import section, you can upload filters and custom presets shared by other users.

Rating:

Refer to Presets page for creating and managing Custom and Import palettes.

Last Edits

This section stores the last 15 corrections, filters or settings used, recorded in the form of thumbnails bearing the date and time of execution, from one session to the next.

If you hover the mouse over the thumbnail, a trash icon appears to let you remove it.

History

The History section shows all the processing and correction steps of your image, from top (oldest) to bottom (most recent).

To view the image at a particular stage, click on the stage in question in the list. The selected step is displayed in yellow, all previous steps (above) are white, and all subsequent steps (below) are grayed out: if you correct the image at this point, the grayed out steps will not be applied to the image.

In split or side-by-side display mode, you can apply a step to the left view from the history by moving the History selector (the yellow arrow on the left edge of the section).

Instant Help

The Instant Help section (Nik Analog Efex only) displays tool descriptions when you hover over with the mouse, it is activated or disabled in Help > Open/Close Instant Help.

Filtering by Favorites and Recently Used

All Nik plug-ins presets and filters can be marked as Favorites by clicking on the star to the left of the thumbnail. A favorite is indicated by a yellow star, you can cancel it by clicking on the star again.

In each section you can filter the filters and settings by favorites or recently used:

You can combine the two buttons, the section will display the filters and the settings according to the “or” criteria. To disable filtering, click on the buttons.

Search field

Each section of the left panel has a search field for filters and settings:

To reset the search, click the “X” on the input field.

The right panel

The size of the right panel is not adjustable but you can hide or unhide it in different ways:

In addition to the specific tools for the different Nik Collection plug-ins, there are a number of common palettes:

When you scroll the contents of the right panel upwards, the Loupe and Histogram disappear from view.

By clicking the pin located in the top right corner of the title bar of the loupe and histogram palette, you can lock it so that all other tools appear below it.

Magnifing Loupe

The loupe is always visible, regardless of the tools used. You can hide it by clicking on the chevron in the top right corner of the palette.

The loupe permanently displays an image that is set to 1:1 (or 100%) of the image area covered by the mouse. It is divided by a vertical yellow line, the left-hand side showing the image before processing and the right-hand side after processing.

The preview in the loupe can be locked in any place on the image by clicking on the pin and then in the image (inclined pin: inactive, vertical pin: active).

When you enable one of the zoom modes, the loupe is centred by default. You can move around the image by grabbing the tile or by clicking in the floating navigation window.

To move around in the loupe, you need to unlock the pin.

Histogram

The Histogram palette is also always visible, regardless of the tools used. You can hide it by clicking on the chevron in the top right corner of the palette.

The histogram shows the distribution of the brightness levels of the pixels in the selected image, with dark tones on the left, medium tones in the center, and light tones on the right, with the peaks corresponding to the number of pixels per brightness range. The histogram can show all channels or individual channels by clicking on the buttons:

Because you can see brightness values by channel, you will be able to precisely set your tonality (exposure, contrast) and color preferences.

The histogram can also be used to display the clipped values in the image, shown as color masks corresponding to the RGB channel and/or the complementary color affected.

To show the clipping masks, click in the histogram or on the button(s) in the top corners: left for clipped shadows and blacks, and right for clipped highlights and whites.

Clipping indicators (left: lowlights, right: highlights).
Colored masks designate clipping of the corresponding color channel.

The palettes

Although the tools and sliders will depend on the selected filter, rendering, or preset, the palettes have common interface elements:

  1. A checkbox to disable/enable all palette tools and settings (for a quick comparison of an image with and without corrections and effects).
  2. Double-arrow to reset the tools (with the option to retain local adjustments) and copy/paste control points and/or control lines.
  3. An “X” button to close the section (which also disables the effects and corrections applied).
  4. A chevron to collapse or expand the contents of the palette.

Lower bar (plugin version)

In plugin mode, the bar contains the following information and functions:

  1. File source: indicates the name of the host application.
  2. Cancel: cancels the current processing and corrections and closes the plugin. The image in the host application is not modified.
  3. Apply: saves the processing and corrections and closes the plug-in. The image in the host application is modified. If multiple images are opened the button will display Apply all.

Custom Presets

Nik Collection lets you save corrections and renderings in the form of presets, meaning you can easily reuse them on other images and share them with other users.

On this page you will find common features to creating, managing, and sharing presets, except for the following plugins:

Creating a custom preset

You can create and save a custom setting at any point in the workflow:

  1. Apply an existing filter or preset and make the desired corrections with the tools in the right panel.
  2. At the bottom of the right panel, click the Save Preset* button.
  3. In the Custom Presets dialog box, enter a name describing your filter explicitly, to make it easy to find later on.
  4. If you want to save the control points and/or control lines and related local settings, make sure that the save with control points checkbox is ticked (it is by default).
  5. Validate by clicking on Save.
  6. The custom preset appears in the Custom section in the left panel.

Managing Custom Presets

You can take advantage of your Custom Presets with the following features:

  1. Rename: click on the name of the Preset under the thumbnail to activate the input field. Enter the new name and hit Enter to confirm.
  2. Mark as favorite: click on the star to the left of the preset (star turns yellow). Click again to cancel (the star turns black again).
  3. Export: hover over the Preset to display the buttons to the right in the thumbnail. Click the top button to export the Preset so that you can share it. A system dialog box lets you choose the save location before clicking Open.
  4. Update: After adjusting or adding corrections in a Custom Preset, hover over the thumbnail to display the buttons on the right. Click on the curved arrow to update the Preset with the adjusted or added corrections.
  5. Delete: hover over the Preset to display the buttons to the right in the thumbnail. Click on the trash to remove it, a dialog box asks you to confirm (you can disable the warning by checking Do not show again).

Sharing Custom Presets

Custom settings are exported as instructions in simple “.json” text files. No bigger than a few Kb, they can be easily shared as attachments via email or instant messaging. The filename is the default name.

Exporting Custom Presets

There are two ways to export one or more custom presets, in the Custom palette and in the Import palette:

Importing Custom Presets

To import custom presets:

  1. In the Imported section, click on the double arrow to the right of the number of Presets.
  2. In the pop-up menu, select Import Preset.
  3. A system dialog box will open :
    • locate the presets you want to import
    • select the presets to import
    • click on Open
  4. The imported Presets are displayed in the Imported section.

Imported presets can be renamed, marked as favorites, exported and deleted, in the same way as your Custom Presets. However, it is not possible to update the settings: if you want to, apply the imported preset, adjust the settings in the right panel then create a Custom Preset.

Rating:

You can only import custom presets that were created in the relevant plugin. If you have custom presets for multiple plugins, you will need to repeat the import process for each of them.

Control points and lines

Top: control point, bottom: control line (Nik Viveza).

Overview

Control points and control lines are based on U Point technology (developed by Nik Software and acquired by DxO Labs in 2017) which makes it possible to make a precise selection without needing a mask or any other complex tools. U Point is simply an abbreviation of “you point.”

Each of the Nik Collection plug-ins (except Nik Perspective) includes control points and control lines with the corresponding functionality. For example, in Nik Dfine control points and lines let you reduce noise, in Nik Viveza they let you correct the tone and colors, and in Nik Color Efex they let you apply effects and renderings locally.

A control point selects by measuring a number of parameters, specifically – the brightness and color of the pixels to which it is applied.

The operation of a control line is somewhat different, it is not the point that is measured but the pipette located nearby. This pipette can be moved to modify the measurement.

U Point technology then automatically selects the elements and areas of the image that represent similar features to where the point or the control line (and its pipette) is affixed, thus creating a selection mask whose size is defined by a slider.

If two or more control points or lines are affixed on top of each other, the masks will overlap:

  • If the control points and/or control lines are not grouped, you can apply different corrections using the sliders (the masks overlap).
  • If the control points and/or control lines are grouped, the corrections made on one will be the same on the other (the masks are merged).

Other features of control points and control lines:

  • you can move them
  • you can add as many as you like
  • you can combine them
  • you can invert them
  • you can view them with a black and white mask. White indicates where the correction is applied at 100%, black indicates where the correction is not applied (0%), and gray levels indicate the intermediary correction values (average gray = ~ 50% of the correction, etc.).
  • you can group them (and ungroup them)
  • you can rename them
  • you can include them in a preset
  • you can delete them individually or in batches

Rating

U point technology, control points and control lines have also been integrated into DxO PhotoLab’s local adjustment settings.

Interface and general use

Rating

This section looks at general use of the user interface as well as the control point and control line features found across the collection. Specific correction functions and tools are discussed in the chapter of each Nik Collection plugin.

Using control points and control lines

Availability of control points or control lines varies depending on the Nik Collection plugin, as you can see from the table below.

Control point +Control point –Control Line +Control Line –
Nik Analog Efex
Nik Color Efex
Nik Dfine
Nik HDR Efex
Nik Perspective

Nik Viveza

Using Control points

  • In the right panel, click the Add Control Point button.
  • When you roll over the image, the mouse turns into a control point icon.
  • Click in the image to place the control point.
  • The control point appears as a yellow (active control point) or white (inactive control point) dot.
  • When active, a control point has a size slider, a set of color sliders (common to all plugins), as well as sliders specific to the plug-in used (you can hide sliders – see Managing control points and control lines).
  • When the control point is inactive, you can mouse-over it to see the slider and the radius (but to adjust them, you must first activate the control point by clicking on it).
  • Whether it is active or inactive, you can move any control point by dragging it with your mouse.
  • You can adjust the size (or diameter) of the control area with the slider
  • You can add as many control points as you want.
  • To remove a control point, click on it to activate it and press the Delete key on your keyboard. A dialog box will prompt you to confirm (check the Don’t show again box to stop displaying the dialog box).

Using control lines

  • In the right panel, click the add control line button
  • When you roll over the image, the mouse turns into a control line icon.
  • Click on the image where you want to place the control line. Drag the mouse to adjust the size of the control line.
  • A control line is composed of the following elements:
    • a yellow dot (active control line) or white dot (inactive control line) accompanied by a small arrow of the same color, indicating the direction and degree of the gradient in the control area.
    • a dotted line across the width of the image, passing through the color dot. This indicates the area where the correction will be fullest. The line can be moved relative to the other line by grabbing it with the mouse.
    • a second dotted line across the entire width of the image, with a handle (dot). By grabbing this handle, you can stretch or reduce the gradient between the two lines, or rotate the whole thing.
    • a pipette that measures brightness and color (the control line dot is inert, unlike a control point). By default, the pipette is always placed next to the control line dot, but it can be moved anywhere in the image. The brightness and color measurements are taken wherever you place the pipette (no need to click).
  • When active, a control line has a set of color sliders (common to all plugins), as well as sliders specific to the plugin used (you can hide sliders – see the Managing control points and control lines section).
  • When the control line is inactive, you can hover the mouse over it to view the two dotted lines (but to adjust them you must first activate the dot by clicking on it).
  • Whether active or inactive, you can move a control line with the mouse by left-click dragging with the mouse.
  • The second dotted line can be located outside the photo and even outside the frame of the working area. You can locate it using the small arrow next to the control line dot and by moving it to see and change the graduation between the two dotted lines.
  • You can add as many control lines as you want.
  • To remove a control line, click on the dot to activate it and press the Delete key on your keyboard. A dialog box will prompt you to confirm (check the Don’t show again box to stop displaying the dialog box).

Linking control points and control lines

Linking lets you simultaneously apply the same correction to all control points and lines without having to create a group.

You can link multiple control points, control lines and even a mix of control points and control lines:

  • make sure no other control point or control line is active (in the right panel click next to the buttons for adding control points and control lines).
  • in the image click close to the control point or control line that you will be using as the main setting and then, holding the left mouse button, drag a rectangle to encompass the control points and/or the dots of the control lines (the rectangle will have white edges and a white translucent fill).
  • Release the mouse button: all control points and/or control lines are active (and yellow):
    • only the sliders of the control point or the control line where you started to draw the selection rectangle are visible.
    • these sliders will affect all control points and lines in the same way.
    • the size of the area of influence remains independent and changeable, from one control point or line to another.
    • linking control points and control lines does not create a group. Control points and control line dots keep their appearance, unlike when grouping (see Managing control points and control lines).
    • to cancel the linkage and regain the dependency of each control point and/or control line, click anywhere in the image.
    • the linking technique can also be used to remove several points and control lines at once.

Negative control points and control lines

Placing a control point or line with all the settings set to zero will protect as well.

Some of the Nik Collection plugins (see the table in the adding Control Points and Control Lines section) let you apply “Negative” or “Protection” control points and/or control lines.

Indeed, if you apply a control point or line to selectively correct an image element and that, despite your efforts, the correction affects another element or other image portion that you do not wish to alter, putting a negative control point or control line on this element to protect it will prevent the corrections of the first point or line from being applied.

Negative control points or lines are represented by a “-“, sign and they represent exactly the same functions and adjustments as the normal control points or lines.

Here too, the use of black and white masks will help you to verify the action and interaction of the control points or control lines, whether they are normal or negative.

Sliders

Overview

Each Nik Collection plugin has common sliders as well as other sliders that are unique to it and you will find them in two locations:

  • Directly attached to the control point or to the control line dot (see Managing control points and lines for display and masking).
  • In the right panel, when there is at least one control point or line affixed to the image.

When moving a slider attached to a control point or line, the equivalent slider in the right panel will also move, and vice versa.

Sliders attached to a control point or the dot of a control line are positioned below by default, but they adapt to the image, so will not be masked by elements of the interface. For example, if you place a control point or line at the bottom of the image, the sliders will be positioned above the edge. The same applies with the left and right edges; sliders will be positioned on the right or on the left respectively.

Sliders also have the following features:

  • White handles and labels correspond to the tools of each plugin.
  • Black handles and labels correspond to common tools:
    • Size.
    • Lm (Luminance).
    • Chr (Chrominance).
    • Df (Diffusion).
  • The labels are an abbreviation of the corresponding tool; the names are displayed in full when you mouse-over them.ever

Selective Color Sliders

Selective color sliders let you extend or reduce the toleance range of the color covered by a control point or line. This way, you will be able to cover hue and brightness level changes in your correction (e. g. to take into account variations in skin hues or blue sky):

  • Lm (Luminance): Determines the brightness range of the color (defaults to 50%).
  • Chr (Chrominance): Determines the extent of color hue variations (defaults to 50%).

The effect of the selective color sliders being subtle, use the black/white mask for the control point or control line (see Managing Control Points and Control Lines).

Diffusion slider

Diffusion slider, left 100%, right 0%.

Only available for control points, the Diffusion slider lets you adjust the hardness of the boundaries of the area of influence defined by the circle:

  • 100% by default, the edges of the correction area are fully diffused.
  • Move the slider to the left for a more pronounced edge-correction.
  • the diffusion and hardness of the edges also varies with the size of the area, the smaller it is, the harder the edges will be.

The effect of the Diffusion slider is also subtle, use the black/white mask for control points or control lines (see Managing Control Points and Control Lines).

Managing control points and control lines

Local Settings palette

The Local Settings section, located in the right panel, lets you manage the different control points and/or control lines applied to the image, shown as a numbered list. Active control points and/or lines are indicated in yellow.

  1. Create a control point or line: these buttons create a control point or control line to apply local settings. Some plugins also offer the option of creating a negative control point or line (see the Adding Control Points and Control Lines table).
  2. Size: Indicates in % the size of the influence radius of the control point.
  3. Show/Hide mask :
    • the button above the list lets you show/hide black/white masks of all control points and control lines.
    • the button in the list lets you show/hide the black/white mask of the relevant control point or control line individually.
  4. Show or hide local settings: lets you show or hide the sliders at the control point or at the control line dot.
  5. Show/Hide Effect:
    • the checkbox above the checklist deactivates or re-activates all control points and control lines applied to the image, as well as the related corrections and adjustments.
    • the checkbox in the list disables or individually reactivates the control point or control line, as well as the related corrections and adjustments.
  6. Delete: Click on the trash to clear the currently selected control points/lines.
  7. Reset: Resets all sliders and associated settings of the selected points and/or control lines in the list to zero (the name of the control point or control line is shown on the left-hand side, when multiple points and/or control lines are selected the name is “Multiple”.)
  8. Group or ungroup control points or control lines:
    • Group: You can group multiple control points or control lines by selecting them from the list, holding down Ctrl (PC) or Cmd (Mac) then clicking the button (you cannot mix control points and control lines in a group, if you select both, the button will remain gray.) You can create as many groups as you want, in the list groups will be named Group 1, Group 2, etc. You can distinguish a group of control points from a group of control lines due to the icons within the folder icons. In the image, the first control point or control line selected to form the group is indicated by the normal dot and all other points or lines in the group are indicated by a small yellow dot. When applying a correction to one of the control points or control lines, the correction will be applied to all the other control points or lines in the group. Within a group, the size slider of each control point, or the spacing between the dotted lines of each control line, can be adjusted individually. If you have linked control points or control lines, you can also group them by dragging a selection rectangle to over them. If you have linked a mix of control points and control lines, you will not be able to group them.
    • Ungroup: to remove the grouping of control points or control lines, select the group from the list, then press the button. All control points will be displayed as ungrouped so you can delete, modify or create new groups from individual points or control lines.
  9. Duplicate: By clicking this button, you duplicate the current selected control points/lines. You can also duplicate a control point or line by clicking on it while pressing Alt (PC) or Option (Mac), then dragging the mouse to position the duplicate.
  10. Invert: Reverses the mask of selected control points or control lines.
  11. List of control points and control lines: the control points and control lines indicated by a yellow icon and white text are selected and therefore modifiable, gray control points and control lines are inactive and therefore unchangeable.

Rename groups, control points and control lines

You can rename your control points and lines and/or groups of points and control lines, which can quickly become numerous, to help you manage them:

  • In the list of Control Points, double-click on the name of the Control Point or group to rename. The Control Point or group must be inactive when you want to rename it.
  • The name is highlighted: enter the new name directly. The old name is deleted as soon as you start typing.
  • If you just want to change the name, move the flashing input cursor using the left and right arrows on your keyboard.
  • Confirm with the Enter key.

Renaming does not change the order of the Check Points in the list, and there is no automatic alphabetical ordering. Nor can you change the order by drag and drop.
