Drop Shadow

Node icon
Filter

Adds a configurable drop shadow behind the image content, with offset, blur, color, and opacity control.

Drop Shadow generates a shadow beneath the visible content of the image. The shadow is derived from the alpha channel: wherever the image is opaque, a shadow appears behind it. Offset, blur radius, color, and opacity are all adjustable.

Inner Shadow mode renders the shadow inside the content boundary instead. Shadow Only mode outputs just the shadow without the original image, which is useful for compositing the shadow separately.

Render shadow inside subject boundary

Shadow OnlyToggle
Default: false

Output only the shadow without original image

Expand CanvasToggle

Auto-expand canvas so shadow isn't clipped

Notes

Expand Canvas only visible when Inner Shadow is disabled.

  • Use Expand Canvas to ensure the shadow isn’t clipped by the image boundary.
  • Shadow Only mode is useful when you need to composite the shadow on a separate layer.
  • Inner Shadow creates an inset/embossed look. Combine with low blur for a subtle effect.
