If you want to duplicate a layer in Photoshop, there are a few different ways to go about it. One way is to use the Copy Layer command (Ctrl+J). This will copy the layer’s contents onto the clipboard, and you can then paste it into another document or image. Another way is to use the Layer Masking feature. To do this, first select the layer that you want to duplicate, and then click on the Layer Mask icon (the black circle with a white cross inside of it). This will open up the Layer Mask dialog box. In this dialog box, you’ll need to set some properties: First, select the Copy option from the drop-down menu next to “Include in Selection.” This will tell Photoshop that you want to copy the layer’s contents, not just its masking information. Next, make sure that “All Layers” is selected from the drop-down menu next to “Destination.” This will tell Photoshop where you want to paste your copied layer—it’ll be placed on top of all other layers in your document. Finally, set the Opacity value for your copied layer to 100%. This will make it completely invisible—you won’t be able to see or edit it in any way. whichever method you choose, be sure that both your original and copied layers are active before proceeding. ..
