  1. Level Horizon Plugin v1.3 for paint.net 4.0+ Download here as part of my plugin pack: http://forums.getpaint.net/index.php?/topic/32048-v Outdated link: LevelHorizon.zip Install the .dll file the normal way, then restart paint.net. You can do everything this plugin does with the built-in Layers > Rotate / Zoom effect. However, I think you'll find this MUCH easier for leveling a horizon. That roll control is cool, but not very easy to get just the right angle for adjusting a horizon. UPDATES v1.3 - Added Plumb Bob functionality. Corrections of +/- 45* or less count as horizontal, greater than that count as vertical. v1.2 - "+" indicators now red. Added IndirectUI rules. Full project now. v1.0 - Initial release. CodeLab script. Tutorial Let's start with the following image: It looks great, but the horizon isn't level! Let's fix that. Step 1: Load your desired image and use the Effects > Photo > Level Horizon menu. Move the effect UI out of the way so that you can see your image to work on it. Using the black "+" in the effect UI under "Starting position" place it on the left side of your image on the horizon. Then, using the black "+" under "Ending position" place it on the right side of your image on the horizon. Note: Use the + for rough placement, then use the sliders or data entry options for fine control. You should see a dashed line on your image that follows your horizon: Step 2: Once you are happy with the location of the horizon indicator line, click the "Show guidelines" check box to turn off the guidelines and show the rotation effect. You should see the image rotated so that the horizon is now flat. If you look in the corners of the image you should see some checkerboard pattern. This indicates where there is no image. We'll fix that next. Step 3: Adjust the "Zoom" slider until the corners of your image are filled. I usually just click the little up arrow a couple of times and that does the trick! Click OK to finalize your image. Source Code Here is the CodeLab source to the effect: The effect dll you can download above is a little more complex in the UI department, but this will show you the algorithm.

  3. This is a relatively simple chroma key plugin for removing the green background from an image. It's based on the algorithm presented in the paper here: http://www.makebelieve.gr/vl/Publications/SAICSIT99.pdf with an addition to reduce the green hue at the edge of objects. It's a terribly simple routine compared to many and certainly could stand improvement, but seems to do the job as well as many of the $100 programs I've tried. -Tim SimpleChromaKey.zip

  5. So, I was scanning a ton of photographs today and kept having to do the same steps to remove dust from the images. I automated it into a plugin.

Just run it and the white dust specks are gone. There is now a simple UI. Select White or Black and those color specks are gone! It's not perfect. It only works on very small specks.

  7. The main purpose of seam carving is to reduce the width (or height) of an image without scaling (squishing) the image. This effect calculates the line through your photograph with the least amount of changes and deletes that line shifting all pixels over to fill the gap. This is often called "content aware resizing". Use This effect is designed to be used with natural photographs. It is not designed to be used with an active selection. So, before running the effect, press Ctrl-D to remove any active selection. Run the effect and click the OK button. One line of your image will be removed. Note: Version 1.5 allows more than one line to be cut at a time. However, there is a limitation on how many lines can be safely cut at one time. You may find that only a few lines may be cut before you need to run the effect again so that more lines can be safely cut. Version 2.0 removes this limitation. Please be patient when carving more than a few lines at a time. Due to the nature of the algorithm, the entire effect is run in a single thread. So, it may take a few seconds for the effect to show up after you move the slider. If you wish to shrink your photograph even further, press Ctrl-F to redo the effect. Continue pressing Ctrl-F until your photograph is the desired size. Protecting Elements This effect will only carve out areas with full alpha. That is, it will ignore areas of your image where the alpha is set below 255. You can use this to your advantage by selecting any area you wish to protect then use the Adjustments > Transparency plugin to lower the transparency slightly. Once you've finished with all of your carving, use the Adjustments > Transparency plugin to restore your image to full opacity. Download (For paint.net 4.0.6+): http://forums.getpaint.net/index.php?/topic/32048-v You'll find it in your Effects > Photo > Seam Carving menu. NOTE: This is slow on camera sized images. Sliding the slider up to 200 could take a couple of minutes to see anything. This is all due to the fact that it is running the algorithm in a single thread. Updates v2.2 - Improved messaging. Added to my plugin pack. v2.1 - Memory usage cut in half, speed improved, messaging improved. v2.0 - Increases carves up to 200 lines at a time, removed "see it" option. v1.5 - Carve more than one line at a time. v1.1 - Fixed bug where it was producing jagged edges. v1.0 - Initial release. _________________ More info about seam carving here: https://en.wikipedia.org/wiki/Seam_carving _________________
  8. Green Tint Reduction Effects -> Photo -> Green Tint Reduction Description Reduce green tint without introducing Magenta. Technical Description When reducing the Green channel to a reasonable amount, parts of a photo can became Magenta. I wrote a script to check for Magenta's Hue range. That worked, but it had the side-effect of Reds becoming desaturated. Therefore, I also had it check the Saturation amount within that Hue range. Instructions Set the Tint Reduction, and then lower the Red Tolerance as needed. Afterwards, further color adjustment could done with Curves, Levels, ect.

  10. The Laplacian pyramid can be used to improve the overall illumination of photos, typically useful when part of the scene is in shadow. It can also smooth or enhance details in a photo without smoothing edges or introduce halos. Similar filters are used for tonemapping HDR pictures. Unfortunately the processing can take long time on big photos, so have patience... The filter was inspired by the paper "Local Laplacian Filters: Edge-aware Image Processing with a Laplacian Pyramid" by Sylvain Paris, Samuel W. Hasinoff and Jan Kautz. (http://people.csail..../2011/siggraph/) Example on detail enhancement (photo from Toul Sleng prison, Cambodia, © Michael Vinther 2012): Parameters used for example: Download version 1.0.4.0 (2016-02-08): http://meesoft.com/P...ramidFilter.zip Unzip the file in the Paint.NET\Effects folder. You can access the feature from the Effects | Photo menu.
  11. This plugin extracts a color range from image, by leaving pixels of selected color opaque and making the rest transparent. Only alpha values are altered, color remains intact. It is useful if you need to edit certain colors on your image separately: duplicate the image layer and run the plugin to get color-based "selection" for further editing. It is more flexible than Magic Wand or Curves+ which could provide similar results but not always exactly as needed. Menu location: Effects > Photo. Download as part of my plugin pack. Updated to version 2.2 (2008-12-24)! Changes: few UI and code optimizations; moved to Color submenu. Updated to version 2.1 (2008-08-31)! - Compatibility fix for paint.net 3.36 Changes in v2 (2008-01-23): - Effect is now located in Adjustments menu - Added check box "Override Original Alpha" (see details below) - Few minor bugfixes Use the six color controls (on top) to define your color selection, and three adjustment controls (on bottom) to adjust the output. For ease of use, the default color range is defined around primary color. So I suggest to use color picker tool before starting the plugin. Check box near each color control defines whether you restrict color by this parameter or not. Unchecking equals to selecting the full range. Tolerance control makes alpha to fade off gradually, based on color's similarity to selected color. Max tolerance makes full alpha gradient from selected color to it's opposite (for example from full bright to full dark, if brightness from 255 to 255 is selected). Feather control softens edges by blurring alpha channel by selected radius. I recommended to adjust this after all other controls are set, due to heavy impact on processing speed. Base Opacity control adjusts alpha of "non-selected" color. Invert Alpha check box inverts final alpha. Override Original Alpha check box controls how to handle originally transparent/semitransparent pixels: - unchecked (default) -> transparent pixels remain transparent, even if pixel's color match your selected color - checked -> transparent pixels turn opaque if pixel's color match your selected color Reset button returns to default setting (that is: color range from primary color and other controls zero). Note: greyscale pixels are also treated as color, defined by Hue=0, Saturation=0. Example: here I attempted to extract skin tones from the photo. I started with color picker tool and clicked in the middle of his raised arm to get a good color sample. Then opened the plugin, adjusted the color range a bit, finally feathered by amount of 4. Screenshot: You can learn the behaviour of this plugin on my test image, containing hue, saturation and brightness gradients: link. Tip: Feather, Base Opacity and Invert Alpha can be also used independently from color controls (with unchecked Hue/Sat/Brigh); so you may find alternative uses: - Feather - Base Opacity: to "un-erase" erased areas - Invert Alpha: to invert opacity Enjoy!

  13. I prefer to sharpen my photos with unsharp mask, because of finer results compared to built-in sharpen effect. So far I had to use other programs for that operation. Switching between programs is annoying - so I decided to learn the code and design a plugin with features I need. Hope you find it useful too. Menu location: Effects > Photo. Download as part of my plugin pack. Updated to version 3.1 (2008-12-24)! Changes: few UI and code optimizations. Updated to version 3 (2008-08-31)! Changes: Threshold control is re-designed to have much better feel and control over the result. Previous threshold had strong impact already from very small values, while large values were quite useless. The new one is literally "zoomed in" to small values only, so it is easy to find good setting with scrollbar. Updated to version 2 (2008-01-03)! Changes: - re-located the effect into Photo submenu - added Review button (press & hold the button to see original image, release it to see changes) - improved keyboard usability - reduced default Radius to 1 which is more suitable for most of images, especially for screen size photos - Color Mask has now some real impact on results: by aming strength based on pixel color. Range is expanded to 0-200 - Tonal Range control in Highlights tab is reversed, in order to work in same direction as in Shadows tab: increasing the value expands the range - Faster rendering after OK click, especially when image fits to window - Code optimized for Paint.NET 3.2 (though it's still not a PropertyBasedEffect) - Source code available (VS2005 express): sharpen+2src.zip Using the plugin: * use three main controls (on top) to achieve required effect * use adjustment controls (in tabs) to fine-tune the result * re-adjust any control if needed Main controls Those are traditional unsharp masking controls (learn more here): Amount - percentage of sharpening to be applied 100 - 200 usually does the job. Radius - width of area (pixels) around edges to be sharpened 1 is good for small (web) images; 2 - 3 for large (several MP) images. Threshold - minimum level of pixel contrast (brightness difference between pixels) to be sharpened Use it to prevent sharpening of even surfaces like sky or skin. Keep at zero if you want to sharpen fine details. Adjustment controls those naturally don't apply any additional effect, but rather adjust it's strength by percentage from main Amount: Edge Balance Bright Borders - Percent of amount applied to bright side of edge Use it to reduce sharpening halo if it becomes too visible, or prevent oversharpening of bright fine detail, like sunlit hair. Dark Borders - Percent of amount applied to dark side of edge Use this to reduce dark halo (rarely needed). Note: it is not recommended to use Bright and Dark controls together: it would effectively reduce overall amount of sharpening (setting both to 0 is equal to setting main amount to 0). Shadows Strength - percent of amount applied in shadows Use it to reduce sharpening impact to image noise (noise is usually most pronounced in shadows). Tonal Range - level of brightness (at 0 - 255 scale) where shadows adjustment will be applied Range is "soft" control: strength of sharpening rises gradually back to normal through 50 next levels above selected level. Tip: set Strength to 0, move around Range control to find the brightness level where noise kicks in, then re-adjust Strength to appropriate amount. Highlights Strength - percent of amount applied in highlights Tonal Range - level of brightness (at top of 0 - 255 scale) where highlights adjustment will be applied Range is "soft" control: strength of sharpening rises gradually back to normal through 50 next levels below selected level. Color mask Adjusts strength of effect based on pixel color Notes * Strength of controls is NOT equal to "other brand" sharpening tools (like USM in Photoshop or Gimp). For example radius 2 in this plugin is close to radius 1 in Gimp USM (due to differences in Gaussian blur rendering). So don't apply settings recommended in Photoshop tutorials - better trust your own eyes. * Sharpness (edge contrast) is increased through brightness channel only - thus no hue shift is caused (as far as color channels are not clipped); this is another difference from "other brand" USM tools. * Shadow and highlight areas are detected from blurred grayscale image, to achieve more even output spread. Alternative use: Instead of sharpening you can use this plugin for local contrast enhancement - to give extra clarity to a flat, hazy image; for example following settings: Amount 20, Radius 80, Threshold 0. (Be patient with this one: the larger the radius, the slower the effect runs - due to Gaussian blur function rendered in background). ------------------ General recommendations for sharpening (collection of unwritten rules I try to follow) * Sharpening only works on sharp images. Use it to remove lens softness or give 3d look to otherwise flat image. * Don't try to fix blurry images with sharpening - it only makes things worse. Leave it blurry or shoot the photo again. * Sharpening should be the very last image processing operation before save / print, as it actually distorts image detail for better appearance (Generally my preferred workflow is: white balance -> noise reduction -> levels/curves/contrast -> saturation -> crop/resize -> sharpening). * The best sharpening settings depends on output - whether it is web image, small print or large print - every kind has different needs. Do experiments to find most appropriate settings. * For best output preview (to predict the results), use 100% zoom while sharpening a web image, use 50% zoom if sharpening for print. * Images appear sharper on LCD monitors than CRTs. So be careful while using CRT. * Mass production printers at photo stores automatically sharpen every jpg image (while they may keep tif's intact). So keep your settings modest or don't sharpen at all if you are going to use those services.
  14. This plugin is designed to fix excessively contrasty photos, by brightening shadows and/or darkening highlights. Menu location: Effects > Photo. Download as part of my plugin pack. Updated to version 2.2 (2008-12-24)! Changes: few UI and code optimizations; moved to Photo submenu. Updated to version 2.1 (2008-08-31)! Changes: - Plugin now starts with default settings loaded (shadows: 100; smoothing 50) - Compatibility fix for paint.net 3.36 Changes in version 2 (2007-09-20): - Improved core algorithm produces smoother tone transitions - Added "Basic" user interface and re-arranged some previous controls (see below in blue) - Added "Review" button for quick before & after check: hold the button down to see original, release the button to re-apply changes USING THE PLUGIN Start in Basic mode - use Shadows and Highlights controls to get desired brightness; use Smoothing to adjust tonal blending. Switch to Advanced mode to override / fine-tune any settings. BASIC CONTROLS * Shadows - strength of shadow adjustment * Highlights - strength of highlight adjustment * Smoothing - blending of shadows and highlights. Adjust this together with Shadows and/or Highlights controls to get the desired look. Generally low values suite for images with extreme shadows & highlights, higher values for more balanced images. Basic controls actually use sets of Advanced controls. You can switch to Advanced mode anytime to override / fine-tune the settings. ADVANCED CONTROLS Shadows: * Amount - strength of shadow adjustment * Tonal Range - brightness range of shadows to be adjusted (at the bottom of 0 - 255 scale) * Saturation - saturation of shadows Highlights: * Amount - strength of highlight adjustment * Tonal Range - brightness range of highlights to be adjusted (at the top of 0 - 255 scale) * Saturation - saturation of highlights Note: saturation controls are independent from brightness, so alternatively you can only increase saturation - for example adjusting sky color. Smoothing * Local Contrast Radius - preserves local contrast by bluring the original image at selected radius (in the backround) before reading the tonal values. In effect setting Radius 10 - 20 avoids fine textures from becoming flat. Default radius in Basic mode is 12, which is optimized for screen size images. You may need greater radius (30, 50 or more) for large, several MP images. Note that large Radius values slow down processing, so I'd recommend to tune it last. * Local Contrast Intensity - as a side-effect, Radius may produce halo near strong edges - for example around dark objects against bright sky. Intensity control allows to reduce halo. Reducing it too much results in flat look due to loss of contrast. Values between 50 and 100 (%) should be okay. * Compression - amplifies strength of effect progressively towards the extreme shadows/highlights, allowing to reveal much more detail especially from deep shadows. Color Mask aims the strength of adjustment into certain color areas based on selected color balance. For example increase red value while reducing green and blue, to aim majority of adjustment at skintones; or increase blue to aim adjustment at sky. Some extreme before & after samples: Settings applied: Basic mode, Shadows 180, Smoothing 50 Settings applied: Basic mode, Shadows 140, Highlights 40, Smoothing 80

  16. Here is something to play with! Download as part of my plugin pack. Open from Effects>Photo Updated to v1.1 (2009-07-08)! Few usability improvements: * Default color for channel mixer is fixed to a certain green (rgb:76,150,29) in order to produce "standard" gray balance * Removed the "Enable" check box for channel mixer, as now you can return to standard gray by using channel mixer's reset button * Default color for Tint is primary color (was secondary before) The slider controls are same as in my Basic Adjustments plugin. Color wheels are different. - Channel Mixer Adjusts how much weight each color channel transfers to final brightness. If reset to default then „standard“ grayscale is applied. - White Level sets the white point of an image. higher number makes white brighter, lower makes darker. It can be called "exposure" in terms of photography. - Black Level sets the black point of an image. higher number makes black darker, lower makes brighter. - Tone (Dark / Bright) applies "gamma curve", making image look darker or brighter. No shadows or highlights are clipped. - Contrast applies "s-curve", enhancing contrast of middle tones. No shadows or highlights are clipped. - Tint Applies a shade of single color to final image. The result is similar to Colorize effect in PS (based on my few quick tests). Check box „Pick hue and saturation only“ makes it easier to work with the color wheel: when checked, it disables the color value slider and uses constant value around 40 instead of default 100. This is because darker colors are usually better for tint. Uncheck this option to fine-tune the result with color value slider.
