In graphics editing, what does the term "layer" refer to?

In graphics editing, a "layer" refers to a separate element that can hold images and effects. Layers are fundamental to graphic design and image editing software, as they allow for the organization of different components of a project without merging them permanently. This enables artists and designers to manipulate individual elements independently, adjust their visibility, order, opacity, and effects applied to each layer without affecting other layers. This flexibility is essential for creating complex images and designs, as it allows for non-destructive editing, meaning changes can be made without permanently altering the original image.

The concept of layers also enhances collaboration, as different designers can work on various layers simultaneously. Furthermore, using layers allows for easy adjustments and experimentation, making it a powerful tool for achieving the desired visual composition.
