Creating a layer mask typically involves a few simple steps, depending on the software you are using (e.g., Photoshop). Generally, it's about adding a mask to a layer that allows you to selectively show or hide parts of that layer. Here’s how to create a layer mask in Photoshop, based on the reference video snippet:
-
Select the Layer: In the Layers panel, select the layer you want to add a mask to.
-
Add the Mask:
- Click the "Add Layer Mask" button at the bottom of the Layers panel. This button usually looks like a rectangle with a circle inside. This creates a white layer mask, meaning everything on the layer is initially visible.
-
Painting on the Mask: The concept of the layer mask relies on black and white (and shades of gray).
- Black: Hides the content of the layer.
- White: Reveals the content of the layer.
- Grays: Partially reveal the content of the layer, based on the shade.
-
Using Black to "Erase": As shown in the video snippet, select a brush tool, set the color to black, and paint on the layer mask. This will hide the corresponding parts of the layer.
-
Using White to "Recover": To bring back hidden portions of the layer, switch your brush color to white and paint on the layer mask.
Essentially, a layer mask is "on" as soon as you create it. You then manipulate it by painting with black, white, or shades of gray to control the layer's visibility. The mask itself doesn't "turn on," but rather, your painting actions determine what's visible or hidden on the associated layer.
