What is Alpha Lock?

Alpha lock is a powerful tool in digital art software like Krita that enables artists to restrict editing to the transparent pixels of a specific layer or selection. Essentially, it allows you to protect your existing artwork while making changes to the transparent areas only.

According to user JohnK on the Krita forums, “Alpha lock is a feature found in many digital painting programs. It helps you lock the transparency of a layer so that you can only paint on the already painted pixels.”

Now, let’s dive into the step-by-step guide on how to alpha lock in Krita. By following these instructions, you’ll be able to unlock the full potential of this powerful feature.

Step 1: Open Your Artwork

Before you can start alpha locking in Krita, you need to have your artwork ready. Open your existing artwork or create a new canvas to work on. Make sure you have all the layers you want to work with prepared.

Step 2: Select the Layer

In Krita, you can alpha lock individual layers. To begin, select the layer you wish to apply alpha lock to. You can do this by clicking on the appropriate layer in the Layers docker.

Step 3: Enable Alpha Lock

Once you have selected the desired layer, it’s time to enable alpha lock. This feature is accessible through the “Layer” tab in the top menu. Click on the tab and a drop-down menu will appear. From that menu, choose “Lock Alpha” or utilize the convenient shortcut Shift + Alt + A.

Step 4: Observe the Alpha Lock Indicator

When alpha lock is successfully enabled for a layer, you will notice a small checkerboard pattern near the layer’s thumbnail in the Layers docker. This pattern serves as an indicator that alpha lock is active for that particular layer.

Step 5: Make Changes within the Alpha Locked Layer

Now that you have enabled alpha lock, you are free to make changes within the layer without affecting non-transparent areas. This means you can experiment with various brushes, colors, and effects, focusing solely on the transparent pixels. Let your creativity flow!

Step 6: Disable Alpha Lock

If you wish to disable alpha lock for a layer and regain the ability to edit the entire layer, it’s a simple process. Just return to the “Layer” tab in the top menu and click on “Lock Alpha” or use the Shift + Alt + A shortcut again. This will unlock the transparency and allow you to make changes to the entire layer once more.

How to Alpha Lock in Krita – FAQ

Q1: Can I alpha lock multiple layers simultaneously in Krita?

Q2: How can I check if a layer is already alpha locked?

A2: It’s easy to determine if a layer is alpha locked in Krita. Look for the presence of a checkerboard pattern near the layer’s thumbnail in the Layers docker. If you see this pattern, alpha lock is active for that layer.

Q3: Can I use alpha lock on a selection instead of a layer?

A3: Yes, alpha lock can be applied to a specific selection as well. To do this, make the desired selection using Krita’s selection tools and then enable alpha lock. The transparency editing will be restricted to the selected area only.

Q4: Does alpha lock affect layers below the locked layer?

A4: No, alpha lock operates solely within the layer it is applied to and does not affect any layers below it. This allows for precise editing without unintended consequences.

Q5: Can I apply alpha lock to a specific color range within a layer?

A5: Unfortunately, Krita does not have a built-in feature for applying alpha lock to a specific color range within a layer. However, you can manually select and lock specific color areas using Krita’s selection tools to achieve similar results.

Q6: Can I use alpha lock with different blend modes in Krita?
