How to Create a Mask in Adobe Photoshop

1. Open your image in Adobe Photoshop.
2. Select the layer you want to apply the mask to.
3. Click on the "Add Layer Mask" button at the bottom of the Layers panel. This will add a white mask thumbnail next to the layer thumbnail.
4. Paint on the mask with black to hide parts of the layer, or with white to reveal them. You can use the Brush Tool for this.
5. Use the Alt key (Option key on Mac) and click on the mask thumbnail to view the mask in isolation.
6. Refine the mask using various tools like the Brush Tool, Gradient Tool, or Selection Tools to achieve the desired effect.
7. Remember, black hides and white reveals, while shades of grey create varying levels of transparency.

By following these steps, you can easily create a mask in Adobe Photoshop to control the visibility of certain parts of your image.
