Applying Highpass

The Highpass effect suppresses low-frequency areas containing gradual or smooth transitions of brightness levels. This leaves high-frequency areas, or just the edges of an image, containing stark shifts between brightness levels.

Highpass uses either the Gaussian or Circular aperture options. Gaussian aperture affects the red, green, and blue components of color; Circular aperture uses image luminance. You can make the highpass more pronounced by using the Equalize effect.
