  4. I made this plugin to get rid of random ink blots on scanned pages. There are two modes, one builds clusters of pixels outside tolerance of the secondary color, the other builds clusters of pixels within tolerance of the primary color. If the cluster is within the size thresholds, it is painted over with the secondary color. It's found under Effects/Noise Download: Example pics: The source code is available here: This is my first plugin (my first C# project, in fact) so it's not very advanced yet. If you have any suggestions please tell. Also, I couldn't find the formula Paint.Net uses to calculate tolerance, so if you know it, please tell me. 7/16/17 Added Clustering Modes and Linked Sliders 7/15/17 Initial Release
  5. This effect generates "film grain" (or luminance grain). Use it to add some character to otherwise boring-smooth digital image. Especially suitable for black and white photos. Find it as Effects > Noise > Grain Download as part of my plugin pack. Controls Amount – amount of grain. Balance – grain distribution across image brightness. "Shadows" applies more grain to dark parts, "Highlights" applies to bright parts. Tech stuff: basically it uses built-in noise effect at zero saturation, but allows additional balancing of noise level between shadows and highlights.
