Auto Chrome Noise Effect Plugin Model / Result : ( original model from http://www.photo-libre.fr ) What's this? Autochrome is a primilary method to obtain colored photos.

This uses the primary color. Color Variation: ...you could add a random variation to the basic colors to make it less regular. Merge with image: ...This mixes the noise with the image if the color of autochrome and the color of the image are "similar", other pixels are turned to grey scale. red <--> orange, green <--> green, blue <--> purple Mask Orange-Green-Purple: ...If checked the image is replaced by the basic colors where the color of autochrome and the color of the image are "similar". Duration: ...This is a slider to make the basic colors remain stable in horizontal lines. Effect Mix: ...This is a slider to mix the final image with the orignal image to make the effect more or less subtile.

The Kuwahara filter is a noise-reduction filter that preserves edges. It can also be used to create various artistic effects. This plugin is based off the Public Domain Kuwahara filter for ImageJ. Download: Kuwahara.zip Place Kuwahara.dll in your Effects folder. Effects->Noise->Kuwahara The Radius option controls the size of the filter sample area. The Use RGB channels option controls whether the plugin uses the RGB channels or the "brightness" (HSV Value) when calculating the output color. The image on the left is the original image, source: https://imagej.nih.gov/ij/plugins/kuwahara.html. The image on the right is after running the plugin with a radius of 7 and Use RGB Channels checked. Source Code: https://github.com/0xC0000054/pdn-kuwahara

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: ClusterClearEffect.zip Example pics: The source code is available here: https://github.com/edwardx999/PaintDotNetClusterClear 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

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.
