To remove the background from a picture in Krita, you can use a transparency mask. Selecting and applying a transparency mask will make the background transparent. This is the quickest way to achieve a transparent background.
Here's a more detailed breakdown of how to remove the background in Krita:
- Open your image in Krita. Go to File > Open and select the image you want to edit.
- Add a Transparency Mask: In the Layers panel, right-click on the layer containing your image. From the context menu, choose "Add" > "Transparency Mask." A new layer, representing the mask, will appear linked to your image layer.
- Select the Transparency Mask: Click on the newly created transparency mask layer to select it. It's important to note that you're now editing the mask, not the image itself.
- Paint on the Mask:
- Black: Painting with black on the transparency mask makes the corresponding areas of the image transparent.
- White: Painting with white on the transparency mask makes the corresponding areas of the image opaque (visible).
- Grays: Painting with shades of gray will create varying degrees of transparency.
- Use a Brush: Choose a brush that suits the type of background removal you're doing. A hard-edged brush is good for sharp lines, while a soft-edged brush can create feathered edges for a more natural look when dealing with hair or fur.
- Remove the Background: Using black as your color, carefully paint over the areas of the background you want to remove. Zoom in for finer details.
- Refine Edges: If necessary, use white to paint back any areas you accidentally erased. You can also use shades of gray to create semi-transparent areas, which is useful for blending edges.
- Disable or Delete Background Layer (if applicable): If your image already had a background layer (e.g., a solid color), make sure to either disable its visibility (by clicking the eye icon next to the layer) or delete it. This will allow the transparency to be visible.
- Save as PNG or KRA: When saving, use the PNG format to preserve the transparency or KRA (Krita document) to save the whole project with layers. JPEG format does not support transparency and will fill transparent areas with a solid color (usually white).
By using a transparency mask and painting on it with black, white, and shades of gray, you can precisely control which parts of your image are transparent, effectively removing the background.
