Node Overview



Node Properties

MAIN TAB

Preview


  • Show Background

Allows you to show the result of the Channel without the Adjustment applied.

This is useful for color picking. How the background is shown depends on your settings for

'Wipe' and 'Selection Preview'


  • Wipe

A viewport wipe between picked Colors and Background. The wipe position is in percentage of your

paint buffers width. Moving the Paint Buffer will change the position of the wipe midpoint

Flattening the resulting Mask with a Wipe set to lower than 1.0 will result in an incomplete mask




  • Reverse Wipe

Will reverse the Mask/Background from left/right to right/left


  • Selection Preview

Determines the way the Mask Preview is shown. This is in line with Photoshop's "Select Color Range"

Preview Options. Setting the mode to 'Grayscale' is the same as turning off 'Show Background'.

Enhance Selection


  • Enhance Selection

Enhance Selection will try to close small gaps in your selection by internally applying a curve to values and saturation.


  • Range Min

The min point of the curve along which values and saturation are evaluated. Low values here will give broader selection results.
