Tanel Posted August 21, 2007 Share Posted August 21, 2007 (edited) 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.
