What it does

Joe's Soft Spot blurs the image insider of or around a user-specified spot. The spot's size and softness can be adjusted and the spot itself can either contain the blur or blur everything outside it. The resulting effect is similar to a photographic soft spot filter such as the Tiffen Center Spot filter.

Example Images


Original Image

Blur: 20

The Controls

  • Blur (0 - 250)

    Amount to blur the affected portion of the image.

  • Origin

    The centerpoint of the effect circle.

  • Radius (0 - 500)

    The radius of the effect circle.

  • Edge Soften (0 - 200)

    The softness of the blur-circle's edge. A value of zero results in a hard-edged circle.

  • Gaussian

    This setting determines the falloff of the gradient's edge. I think Gaussian looks more natural, so I made it on by default.

  • Invert

    Reverses the affected area between a soft spot and a soft circular frame.

  • Aspect (0.1 - 10)

    Defines the effect aspect ratio. Values less than one skew vertically, values greater than one skew horizontally. This amount is multiplied by the sequence aspect ratio, so a value of 1 is round no matter what aspect ratio is being used in the sequence.

  • Mode, Opacity

    Composite controls to specify how to apply the blurred image back onto the original.
