A. While the vignette blur feature is no longer available, you can manually create a vignette effect using the available tools. Start by selecting the 'Blur' tool and apply it around the edges of your image. Then, use the 'Eraser' tool to refine the area where you want the vignette to be less pronounced, creating a gradual transition.

B. Alternatively, you can use the 'Gradient' tool to create a darkened border around your image. Select a radial gradient, adjust the colors to black or dark shades, and apply it to the edges of your photo, adjusting the opacity to achieve the desired vignette effect.
