Poster mask feathering gradient

Quick answer：

Feathering in graphic design refers to the transition between an object and its background, creating a smooth and gradual blend. This technique is often used in poster design to make text or images seamlessly integrate with the overall design. Gradient, on the other hand, is a smooth transition of color or value, commonly seen in backgrounds or fills. Combining feathering and gradient in poster design can enhance visual appeal and create a cohesive aesthetic.
