How Do You Add a Texture Layer Mask in Photoshop?

Adding a texture as a layer mask in Photoshop allows you to reveal or hide parts of a layer based on the texture's lightness and darkness. Here's how to do it:

Method 1: Using the Layer Mask Icon

1. Place your texture: Select File › Place Embedded, then navigate to your texture image.
2. Create a layer mask: In the Layers panel, select the layer you want to mask. Click the Add Layer Mask icon (a rectangle with a circle inside). This creates a mask linked to the layer.
3. Apply the texture: With the layer mask active (it will be highlighted), paste your texture image onto the mask. The lighter parts of the texture will reveal the underlying layer, while the darker parts will hide it. You can adjust the texture's blending mode and opacity for further refinement.

Method 2: Creating a Mask from a Selection

1. Open your texture and your main image: Have both images open in Photoshop.
2. Select your texture: Using the selection tools (e.g., Lasso, Marquee, or Quick Selection), select the area of your texture you wish to use as a mask.
3. Copy the selection: Copy the selected portion of your texture (Ctrl+C or Cmd+C).
4. Create a new layer mask: On your main image layer, click the Add Layer Mask icon.
5. Paste the selection: Paste your copied texture into the layer mask (Ctrl+V or Cmd+V). The pasted texture will now act as the layer mask.

Method 3: Using a Clipping Mask (for selective texture application)

1. Place your texture above your target layer: Ensure your texture layer is positioned directly above the layer you want to affect.
2. Create a clipping mask: Right-click on the texture layer and select Create Clipping Mask. The texture will now only affect the layer below it.

Note: Remember to experiment with blending modes (like Multiply, Overlay, or Soft Light) and opacity adjustments to achieve your desired effect. These methods allow for a wide range of creative possibilities beyond just simple reveal/hide functionality.
