Color Range Mask

カラーエディタ / Mask / Layers

Capture One enables you to create a mask from a color range using the Color Editor tool.

Working with a color range selection

Capture One enables you to create a mask by a color range using the Color Editor tool. This option works well for a broad range of selection tasks, from subjects with difficult to brush edges to those with clearly defined colors. Note, however, while a color range helps to target the selection for the creation of the mask, its success also depends on what kind of adjustment is to be applied. For example, a negative clarity adjustment used to smooth skin-tonesdoesn’t require a precise mask, whereas an exposure adjustment typically requires a more targeted selection. Therefore, this selection option works well when a localized contrast adjustment is required using the combined RGB or Luma Curve tool. 

When modification of the color range is required, either the Advanced or Skin Tone options can be used by adjusting the wire-frame to in the color wheel to either expand the range or restrict it. With multiple color range selections made using the Advanced option, only the highlighted selection is used to create a separate layer and mask. However, for even greater control, each one can be used to make an additional layer each with their own mask, and like any selection mask in Capture One, each one can still be tidied up using the erase brush (E).

Creating a mask from a color range

Capture One enables you to create a mask quickly from a color range selection using the Color Editor tool.

  1. Go to the Color Editor tool and select the color or area intended for local adjustment on the image using the Color Editor tool’s color picker (pipette icon).
  2. When modification of the range is required, use the color picker from the Advanced or Skin Tone options or cursor group and adjust the wire-frame to suit. When multiple selections are made using the Advanced option, only the highlighted selection is used for the mask. However it is possible to make a mask for each selection. To display the selected color range in the Viewer, enable the View selected color range option.
  3. With the color selection highlighted in the Color Editor, click on the the Color Editor tool’s Action menu button (… icon), and select Create Masked Layer from Selection. A dialog opens showing the progress of the creation of the mask.
  4. A new separate adjustment layer is created in the Layers tool, complete with a corresponding mask for that color selection.
  5. Tidy up areas not needed using the erase brush (E).
  6. The mask can now be used to apply adjustments.

Creating masks from a color range for multiple images

The Color Editor tool’s ability to automatically create a mask from a color-based selection can also be used for multiple images. This is particularly useful for batch editing of an identical subject, providing, of course, the same selection is required for masking and subsequent adjustment. The following instructions assume that the Edit All Selected Variants option is selected (if not, click on the multiple thumbnail icon in the Tool-bar turning the icon to orange). Individual images may require tidying up using the erase brush (E).

  1. Select a variant group, or a series of similar images captured in a single session from the Browser.
  2. Go to the Color Editor tool and select the color or area intended for local adjustment on the primary variant using the Color Editor tool’s color picker (pipette icon). When greater precision is required use the color picker from the Advanced or Skin Tone options or cursor group.
  3. To display the selected color range in the Viewer, enable the View selected color range option.
  4. With the color selection highlighted in the Color Editor, click on the the Color Editor tool’s Action menu button (… icon), and select Create Masked Layer from Selection. A dialog opens showing the progress of the creation of the mask.
  5. A new separate adjustment layer is created in the Layers tool for each image variant, complete with a corresponding mask for that color selection.
  6. The masks can now be used to apply adjustments to them.
