Effects node
Edge Sobel
Classic Sobel edge detection. It outputs how sharply the picture changes as greyscale lines, and Invert flips black and white.

What it does
Edge Sobel is an image effect: it changes the picture that flows through it. It takes picture in and gives picture out.
Try it
Wire it into a Displacement node so only the edges of a photo lift off the surface.

Controls
Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
| Control | Range or options | Default |

| amount | 0.1 to 8 | 1.5 |
