What dictates the stacking order of layers in an image editing application?

The stacking order of layers in an image editing application is determined by the arrangement of layers in the layers palette. This arrangement defines which layers appear on top of others in the final composition. Layers that are positioned higher in the layers palette will be displayed above those that are lower, allowing designers to control visibility and how elements overlap. Understanding this is essential for effective editing and compositing, as it enables the artist to manage foreground and background elements dynamically.

While the order in which layers are created may influence their initial stacking, any subsequent adjustments to the layers palette can completely reconfigure how they are presented. Therefore, it is the placement within the layers palette that ultimately dictates the final appearance of the composition.
