In graphic design and photo editing, the "Feather" of a mask is a crucial property that controls the softness of the edges of the mask. When you adjust the Feather, you are essentially determining how much the mask's transition blends with the underlying layers. A higher feather value results in softer edges, which can create smoother transitions and make the adjustments less harsh, providing a more natural look.

Choosing 45px as the feather value indicates a moderate level of softness, allowing for a more balanced transition effect that can enhance the vignette's appearance without overpowering the composition. This value strikes a good balance between visibility and subtlety, making it suitable for ensuring that the vignette effect looks integrated into the overall design.

Other values might either be too subtle (lower values) or too extreme (higher values), potentially diminishing the intended visual effect of the vignette. Thus, 45px is a sensible choice for achieving a soft and effective vignette mask on the layer.
