These parameters simulate lens vignetting darkening the edges of the image.
— Focal Factor: Adjusts how far the vignetting extends into the image.
— Geometry Factor: Affects how dark the vignetting is and how pronounced the edges are.
— Tilt Amount: Affects how balanced the vignetting at the top of the image is versus the bottom of the image.
— Tilt Angle: Affects how balanced the vignetting left of the image is versus the right, but only when Tilt Amount is set to something other than 0.
Add Dirt
These parameters let you simulate dirt particles (not dust) that have adhered to the film. These are larger specks, although there’s several ways you can customize these.
— Dirt Color: This control lets you choose what color you want the dirt particles to be (black simulates dirt on a print, while white simulates dirt on a negative).
— Changing Dirt: This checkbox lets you alternate between simulating temporally unstable dirt on the film (checkbox on) and dirt on the lens that doesn’t move (checkbox off).
— Dirt Density: Lets you choose more or less dirt particles appearing over time.
— Dirt Size: Lets you choose the average size of dirt particles to appear.
— Dirt Blur: Lets you defocus the dirt, so it’s not so sharp.
— Dirt Seed: Changes the random distribution of dirt when you change this value, but for any given value, the results for any given set of control adjustments remain consistent.
Add Scratch
Five sets of Add Scratch parameters let you add up to five scratches to the image, simulating something scratching the emulsion while the film played.
— Scratch Color: Lets you choose the color you want the scratch to be (scratches can be a variety of colors depending on the depth of the scratch, type of film, and method of printing).
— Scratch Position: Lets you adjust the scratch’s horizontal position on the image.
— Scratch Width and Scratch Strength: Let you adjust the scratch’s severity.
— Scratch Blur: Lets you defocus the scratch.
— Moving Scratch: This checkbox lets you choose whether the scratch is jittering around or not.
— Moving Amplitude: Determines how far the scratch moves.
— Moving Speed: Determines how fast the scratch moves.
— Moving Randomness: Determines how the scratch meanders about.
— Flickering Speed: Determines how much the scratch flickers lighter and darker in severity.
