# G’MIC Blend Standard node

This documentation is for version 1.0 of G’MIC Blend Standard (eu.gmic.BlendStandard).

## Description

Note: In custom formulas, a and b respectively stand for the values of the base layer and the blend layer, and are defined in value range [0,1].

Note: This filter needs at least two layers to work properly. Do not forget to set the Input layers option below to handle multiple input layers.
