Masks in Affinity Photo, Designer, and Publisher allow you to selectively hide or reveal portions of a layer, offering precise control over image editing and design elements. They are essentially stencils that control the visibility of the layer beneath. This is a powerful technique for compositing images, creating intricate designs, and non-destructive editing.
Types of Masks in Affinity
Affinity primarily utilizes layer masks. These are separate layers linked to an underlying layer, acting as a control for its visibility. Black on the mask hides the corresponding area of the underlying layer, while white reveals it; greys create varying degrees of transparency.
-
Creating a Layer Mask: To add a layer mask, select the layer you want to mask, then click the "Add Layer Mask" button (usually a rectangle with a circle inside). A new, white mask layer will appear, linked to your original layer.
-
Painting on the Mask: Using a black brush, you can paint onto the mask to hide parts of the underlying layer. A white brush reveals those areas. This allows for precise control of the masking effect.
-
Using Images as Masks: You can also use an image (e.g., a PNG with transparency) as a layer mask. This is achieved by simply dragging and dropping the image onto the layer mask.
-
Vector Masks: Affinity also allows the creation of vector masks, providing the flexibility to apply precise shapes as masks using vector tools.
Practical Applications of Masks
Masks are incredibly versatile and useful for various tasks:
- Compositing: Seamlessly integrate images by masking out unwanted portions of each layer.
- Retouching: Hide blemishes or unwanted objects in photographs.
- Creating special effects: Generate unique effects by selectively revealing parts of a layer.
- Non-destructive editing: Masks enable you to modify your images without permanently altering the original pixel data.
Example Workflow: Image Compositing
- Import your base image and the image you want to add (e.g., a person to a landscape).
- Create a new layer with the person image placed on top of the landscape.
- Add a layer mask to the person layer.
- Using a black brush, paint on the mask to reveal the landscape around the edges of the person, seamlessly blending them together.
