1, Range: The mask is mainly used to control the transparent area of the layer, and the visibility of the layer is controlled by painting black, white or gray on the mask. Shape layer is to paint a color or gradient on the selected area, or to create a selection with shape layer and fill the selection with color, so the application scope of shape layer is wider.

2. Operation mode: The use of the mask needs to be drawn or corrected by hand, which can be achieved by using tools such as brushes and erasers. The shape layer can quickly modify the shape layer by adjusting its properties, such as fill color, irregular shape and border size.

3. Transparency: Both the mask and the shape layer can adjust the transparency, but the mask can control the transparency of the whole layer, while the shape layer can only control the transparency of the selection. Generally speaking, masks are more suitable for fine decoration in complex images, while shape layers are more suitable for creative painting and typesetting design.
