Oil film: a prism light effect with dense rainbow interference rings
Think of petrol on a wet road. Oil film shrinks the Ripple field to a Shape scale of 64 so more rings crowd into the frame, then opens Spread to 96 until they bleed into each other. Complexity at 11 fills every ring with hair-thin prism lines, Grain at 14 roughens the charcoal backdrop like asphalt, and a Speed of 12 lets the sheen creep instead of flow.
Make it yours
Clean up the sheen for product pages
Grain is 14 here, the grittiest setting among the prism presets. Take it under 5 and the same rings feel like a soap bubble or holographic foil, a better match for beauty and packaging work.
Open the rings up
Complexity at 11 is one step from the control's ceiling of 12 and produces the moire-like shimmer. Dropping it to 4 or 5 replaces the fine lines with broader color bands that survive small sizes and video compression.
FAQ
Why does Oil film look so unlike Prismatic ribbon if both use the prism spectrum?
The colors are the same; the geometry is not. Prismatic ribbon bends one band along an arch, while Oil film uses the Ripple field at a small scale with nearly maximum Spread and Complexity. That turns a single rainbow into overlapping rings of thin-film color, closer to iridescence than to a classic prism beam.
How it works
Pick a field and a curve
Choose one of 5 fields and 4 curves, or start from one of 17 looks such as Prismatic ribbon or Iridescent halo.
Tune the light
Adjust scale, bend, spread, detail, angle, glow, grain and speed.
