Masks

Masks in GrossGrade are user-defined local areas of the image that are affected by the color correction of the current processing layer.

 

If one of the masks is currently selected in the layers panel, the toolbar always contains the following standard controls:

Tools_BaseMask_RUS

With their help, you can control the parameters of the mask display on the screen.

Button in the form of an eye icon enables/disables the mask display in the preview window.

Button in the form of a translucent mask enables/disables the display mode "overlay". When overlay mode is enabled, the mask is displayed with the selected color over the image. When overlay mode is disabled, the mask is displayed in grayscale.

Horizontal slider controls the opacity of the mask overlay.

Square button on the right allows you to select the overlay color.

 

Depending on how you create a mask, there are the following types:

 

Click toggle to expand/collapse hidden blockMaskIcon_Smart Smart mask

This is a mask created manually with a tool such as a brush. However, drawing of the mask is the work with the isolated colors. This means that when you add a certain area of the image of a certain color to the mask, all other areas of the same color will be added at the same time. This type of masks is fully supported in the 3D LUT export process.

Mask tools

Tools_SmartMask_ENGIf one of the smart masks is currently selected in the layers panel, the toolbar contains the following controls.

 

"opaq." button - make the current mask completely opaque (color correction of the layer will appear as much as possible).

"tran." button - make the current mask completely transparent (layer color correction will be completely hidden).

"inv." button - invert the current mask, i.e. make transparent areas opaque, and vice versa.

"dyn." option - use dynamic colors (use previous layers color correction), otherwise use static colors (the original image colors).

 

"size" slider - changes the size of the brush.

"hardn." slider - changes the hardness of the brush that determines the area of a smooth fading of the boundaries of the brush.

"opac." slider - changes the opacity of the brush.

"select." slider - changes the color selectivity of the brush. Color selectivity affects the interaction of the brush with colors, whose number is small in comparison with all the colors, placed under the brush. With low selectivity, few colors are more exposed to the brush and vice versa.

 

Click toggle to expand/collapse hidden blockMaskIcon_Raster Raster mask

This is the most common mask created manually with a tool such as a brush. It is suitable for quick selection of individual elements of the image, if necessary, to apply color correction locally. This type of masks is unsupported and ignored in the 3D LUT export process.

Mask tools

Tools_RasterMask_ENGIf one of the raster masks is currently selected in the layers panel, the toolbar contains the following controls.

 

"opaque" button - make the current mask completely opaque (color correction of the layer will appear as much as possible).

"transp." button - make the current mask completely transparent (layer color correction will be completely hidden).

"invert" button - invert the current mask, i.e. make transparent areas opaque, and vice versa.

 

"size" slider - changes the size of the brush.

"hardness" slider - changes the hardness of the brush that determines the area of a smooth fading of the boundaries of the brush.

"opacity" slider - changes the opacity of the brush.

 

Click toggle to expand/collapse hidden blockMaskIcon_Calculated Calculated mask

This is a mask that is not created manually (not drawn), but is calculated according to certain rules in the processing module at the discretion of the module developer and/or the end user. Since this mask is calculated all the time when working with the color correction module, you cannot change individual areas of the mask with a brush. This type of masks is fully supported in the 3D LUT export process.

 

When you create a calculated mask for a layer, you can load a separate module that acts as a mask into it (for this, a "custom module" in the module drop-down list must be selected). To loaded module performed the mask role, it has to use the input port mask of the node Out in the module processing graph. The content of the mask is the data coming to this port. The port mask of the node Out has the type weighting function and is a replicable port.

 

In addition, all currently existing layers and other existing calculated masks are available in the module drop-down list. If you select one of the layers, the current mask will use that layer as a mask. If you select one of the other existing calculated masks, the current mask will use a reference to that mask so that you can use the same loaded module as multiple masks for multiple different layers at the same time, some of which can be inverted if necessary.

Mask tools

Tools_CalculatedMask_ENGIf one of the calculated masks is currently selected in the layers panel, the toolbar contains the following controls.

 

"Module" drop-down list - select the module/layer from which the calculated mask will be taken.

"mask" field  - is the serial number of the mask port of the node Out of the selected module. This field becomes visible only when the module used as the mask uses more than one instance of the mask port of the Out node.

"invert mask" option - invert the current mask, i.e. make transparent areas opaque, and vice versa.
