How to Invert a Vector Mask in Photoshop

Inverting a vector mask in Photoshop can be achieved through several methods, depending on your workflow and preferences. Here's how:

Method 1: Using the "Subtract Front Shape" Path Operation

This method is ideal when you've created your vector mask using the Pen Tool and have a defined work path.

1. Select the Path: Using the Path Selection Tool, select the path that defines your vector mask.
2. Invert the Path: In the Options bar, locate the Path Operations and select "Subtract Front Shape". This effectively inverts the selected path, thus inverting the vector mask.

This method directly manipulates the path, providing precise control over the inversion. (Source: jkost.com)

Method 2: Inverting the Mask Thumbnail

This is a quick method to reverse the visible effect of the mask, but doesn't change the underlying path itself.

1. Select the Mask Thumbnail: In the Layers panel, Shift-click the vector mask thumbnail. This will temporarily disable the mask.
2. Re-Enable Inverted Mask: Shift-click the thumbnail again. This time, the mask will reappear but with its effect inverted. (Source: jkost.com)

This method is useful for quickly previewing the inverted effect without altering the original vector mask.

Method 3: Using the "Image > Adjustments > Invert" Command

This method inverts the appearance of the mask, but not the vector path data itself. It’s a simple way to get an inverted visual result.

1. Select the Layer: Ensure the layer with the vector mask is selected.
2. Invert the Mask: Go to Image > Adjustments > Invert (Cmd+I on Mac, Ctrl+I on Windows). This command inverts the mask's effect, displaying the previously hidden areas and hiding the previously visible ones. (Source: rockymountaintraining.com)

This is the fastest method for visually inverting the mask but is not recommended for fine adjustments to the vector path itself.

Method 4: Using the "Inverse Path" Context Menu

Some sources suggest using a right-click context menu option, “Inverse Path,” to achieve inversion. While this is plausible, the exact availability may vary with Photoshop version and workflow. This method directly works with the path and modifies it, offering precise control. (Source: maxobiz.com)

Important Considerations:

• The method you choose depends on how you intend to use the inverted mask.
• Methods 1 and 4 directly modify the vector path, offering the most control.
• Methods 2 and 3 provide quicker visual inversion but don't alter the path's underlying data.
