Simulates dirt on the camera lens and in-lens reflection. Subtle use of this effect can often be helpful in adding realism to CGI shots or elements, and making them feel less perfect or artificially precise.
The dirt element can be procedurally generated from various seed values, or you can use another layer as the dirt source. The in-lens reflection flaring can be generated from the applied layer or from another source.
- Preset: Choose any of the built-in presets for immediate results, or as a starting point for further adjustments.
- Light Layer: Choose the layer whose luminance will be used to illuminate the lens dirt. When None is selected, the contents of the layer to which the effect is applied will be used. Select any other layer on the timeline to use its contents instead.
- Dirt Layer: Choose the layer whose contents will be used to generate the lens dirt. When None is selected, the dirt generated by the Lens Dirt effect will be used. Select any other layer on the timeline to use its contents instead.
- Threshold: Set the minimum luminance level at which the contents of the Dirt layer or dirt map will be visible. Higher values restrict the effect to brighter areas of the frame, thereby making the effect more subtle.
- Intensity: Adjusts the brightness of the dirt. Higher values make the effect more obvious.
- Blur: Blurs the light layer which illuminates the dirt, without altering the detail if the dirt itself. For realistic results this value should be kept relatively high.
- Pivot Angle: Modifies the angle at which the light layer enters the virtual lens. For realistic results this value should be kept relatively high.
- Blend: Choose the blend mode used to composite the effect onto the underlying layer.
- Dirt Map: When no Dirt Layer is selected, the Lens Dirt effect will generate its own dirt map.
- Seed: Each seed value contains a unique procedurally generated dirt map. Change the seed if you want to use a different dirt map.
