Simulate the organic textures that can be created in darkroom processing on your digital images. Choose between Streaked, Corroded or Concrete styles, and vary the effect by applying the texture in either white or black. Use the Strength slider to adjust the opacity and tone of the texture globally, and use control points to adjust or remove the effect selectively.
