      Effect:Circular Lens
      Category:Special Effects
      Speed:Fast

      Description: The Circular Lens Effect produces a circular/oval Color 1 inside of Color 2 or black.

      If you enable the Fit To Brush Option you will paint with the Circular Lens sized to your brush.

       
      Options: The Circular Lens Effect has the following Options Pane:

      Outer Radius:This value sets the distance from the center of the Outer edge of the Effect. If this value is larger than Inner Radius, then areas outside the Outer Radius are Color 2, and areas inside the Outer Radius are Color 1. If this value is smaller than Inner Radius, Color 1 and Color 2 are reversed.
      Inner Radius:This value sets the distance from the Outer edge of the Effect to the pure Color of the inner portion of the Effect. This basically sets the size of the gradient between the inside and outside. If this value is smaller than Outer Radius, then areas outside the Outer Radius are Color 2, and areas inside the Outer Radius are a gradient to Color 1, and areas within the Inner Radius are purely Color 1. If this value is larger than Outer Radius, Color 1 and Color 2 are reversed.
      Color 2 Bleed %:This value sets the amount that Color 2 Bleeds into the Effect. If set to 0% there is no bleed and Color 2 becomes black, regardless of what it originally was. Any value higher than 0% allows the true Color 2 value to bleed through. At 100% you have a pure Color 2.
      Fit To Brush:If set to a Red X the Effect spans the screen such that as you paint you reveal the Effect. When set to a Green Check Mark the Effect is sized to the brush such that as you paint the entire Effect is within the brush itself.
      Output Color 1:By default this is set to REPLACE which means that the set color will be output to Color 1. You can change this as explained in Options Pane Color Mixers.
      Output Color 2:By default this is set to IGNORE which means that the Color 2 will be ignored (the original Color 2 will be kept). You can change this as explained in Options Pane Color Mixers.

      Example: The following examples show the Circular Lens Effect.

      This first image combine three Effects. In Slot 1 is our Texture Effect with our Arches National Park photo loaded as the Texture. In Slot 2 we put our Colorful Curves Effect with Output Color 1 set to Ignore and Output Color 2 set to Replace. In Slot 3 we have our Circular Lens Effect with default values:

      Because Color 2 Bleed % is set to 0% the Effect is blended to black instead of the Colorful Curves Effect.

      We now set the Color 2 Blend % of the Circular Lens Effect and set it to 100%. The result is that the Colorful Curves is used as Color 2 instead of black:

      We now set the Inner Radius of the Circular Lens Effect to be just slightly smaller than the Outer Radius. You can see how this makes the transition much harder, rather than softer:

      In this final image we have reversed the Inner Radius and Outer Radius values from their default values. Inner is now larger than Outer. You can see that this reverses how Color 1 and Color 2 are used:
