What is one way to duplicate a layer in Photoshop?

Duplicating a layer in Photoshop is a fundamental operation that allows you to create an exact copy of an existing layer. The method of right-clicking on the layer in the Layers panel and selecting "Duplicate Layer" is a straightforward and effective approach. This action opens a dialog box where you can rename the new layer if desired, giving you immediate control over the duplication process.

Duplicating a layer using this method preserves all properties of the original, including effects, masks, and blending modes. This can be especially useful when you want to modify the copy without affecting the original layer. The ability to create multiple duplicates or alter the properties of the duplicate enables extensive flexibility in editing.

Other options do not facilitate the creation of an independent duplicate layer. Dragging a layer to the trash would delete it rather than copy it. Merging a layer combines it with another layer, effectively losing the original layer's individuality. Changing a layer's name simply modifies its identifier in the Layers panel without affecting its contents or duplicating it.
