Auto-shoulder analyzes each frame seperately and large color shifts can occur when something, such as a highlight is in one frame and not the next (for instance, a refleaction off a moving piece of glass). To compensate for this, we recommend using the Shoulder tool, which allows all controls to be set manually rather than them being set automatically by Looks.
By default, the Shoulder tool can only be placed in the Camera section of Tool Chain. To place the Shoulder tool in the Post section, hold the 'Alt/Option' key and move the Shoulder tool to Post, located in the far right of Tool Chain.
Step 1: Select Shoulder tool (either from Tool Chain or Tools Drawer) and hold 'Alt/Option' key.
Step 2: Drag Shoulder tool to Post in Tool Chain.
