To copy an image into a layer mask, follow these steps:
Step-by-Step Guide
Here's a detailed, step-by-step guide to help you copy an image into a layer mask using techniques similar to those in the reference:
- Select the source layer: In your Layers panel, click on the layer whose content you want to copy. This is the image you'll be transferring to the mask.
- Select the content:
- For layer content: Press Ctrl + click (or Cmd + click on macOS) on the layer thumbnail. This will select the visible pixels of your layer.
- For the entire document: If the content covers your entire document, simply press Ctrl + A (or Cmd + A on macOS) to select all.
- Copy the selection: Go to Edit menu and choose Copy (or press Ctrl + C or Cmd + C).
- Deselect the selection: Press Ctrl + D (or Cmd + D on macOS) to deselect the copied pixels. This step is important so you don't make changes to the image you've copied.
- Target the layer mask: Hold Alt (or Option on macOS) and click on the layer mask thumbnail. This action will make the mask active and visible. Now the mask is ready to receive the copied content.
- Paste the copied content: Go to the Edit menu again and choose Paste (or press Ctrl + V or Cmd + V). The previously copied image is now pasted into your layer mask.
Practical Considerations
- Understanding Layer Masks: Layer masks work by using grayscale values to determine the opacity of the layer. Black hides, white reveals, and shades of gray control transparency.
- Adjusting the Mask: After pasting, you can further adjust the mask using tools like the paintbrush to fine-tune the image's visibility.
- Reusing Masks: Once a mask is created, you can copy the mask to other layers by dragging the mask onto the new target layer or using similar copy-paste procedures.
Summary
The process is straightforward once you're familiar with the steps. Remember these key points:
| Step | Action | Keyboard Shortcut (Windows) | Keyboard Shortcut (macOS) |
|---|---|---|---|
| Select Layer | Click on desired layer in Layers panel | N/A | N/A |
| Select Content | Ctrl + Click on thumbnail (or Ctrl + A for full document) | Ctrl + click or Ctrl + A | Cmd + click or Cmd + A |
| Copy Selection | Edit > Copy | Ctrl + C | Cmd + C |
| Deselect Selection | Ctrl + D | Ctrl + D | Cmd + D |
| Target Layer Mask | Alt + Click on mask thumbnail | Alt + click | Option + click |
| Paste Content | Edit > Paste | Ctrl + V | Cmd + V |
By using these steps, you can copy any image or selection directly into a layer mask, giving you fine control over the transparency and visibility of layers in your image editing workflow.
