What exactly is a color fringe correction? This blog post is intended to explain the problem and the solution we&#8217;ve provided in Lightroom 4.1.(For ACR customers it will also be included an upcoming version of ACR7 for Photoshop CS6, currently available as a public beta)<\/p>\n<p>The content in this post has been written by Eric Chan, the developer primarily responsible for implementing the solution. (Photos have been attributed where requested.)<\/p>\n<h2><strong>Overview<\/strong><\/h2>\n<blockquote><p>Red-green and blue-yellow fringes at the image periphery result from lateral chromatic aberration. This problem is relatively easy to fix, and ACR &amp; LR already have tools to do so. On the other hand, purple and green fringes in out-of-focus areas and along high-contrast boundaries are much more problematic. These fringes result from axial chromatic aberration (wavelength-dependent focus shift), aberrations in sensor microlenses, and flare. In most cases, purple fringes appear in front of the plane of focus, and green fringes appear behind the plane of focus. The aberrations can happen anywhere in the image, not just the image periphery. Sometimes, they are so strong that they&#8217;re easily spotted in small previews, such as proxies and thumbnails (thus, not only visible at 100% pixel view!). Axial CA affects nearly all lenses, from inexpensive cell phone lenses to very expensive top-of-the-line lenses. It is particularly pronounced with fast lenses at wide apertures. Hence, an improved defringe control should appeal to photographers shooting portraits, events, weddings, sports, etc. &#8212; anytime that high-speed lenses are used.<\/p><\/blockquote>\n<h2><strong>Example<\/strong><\/h2>\n<blockquote><p><strong>Example 1: Backyard<\/strong><br \/>\nThe branches and leaves have very strong purple fringing, visible even in the small\u00a0overview image.Overview, original: <img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/lrj.mattalbright.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2012-04-25-at-3.01.20-PM.png\" alt=\"Screen Shot 2012 04 25 at 3 01 20 PM\" width=\"600\" height=\"398\" border=\"0\" \/>Overview, with defringe: <img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/lrj.mattalbright.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2012-04-25-at-3.01.29-PM.png\" alt=\"Screen Shot 2012 04 25 at 3 01 29 PM\" width=\"600\" height=\"399\" border=\"0\" \/>Closeup, original: <img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/lrj.mattalbright.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2012-04-25-at-3.01.40-PM.png\" alt=\"Screen Shot 2012 04 25 at 3 01 40 PM\" width=\"600\" height=\"400\" border=\"0\" \/>Closeup, with defringe: <img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/lrj.mattalbright.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2012-04-25-at-3.01.50-PM.png\" alt=\"Screen Shot 2012 04 25 at 3 01 50 PM\" width=\"600\" height=\"398\" border=\"0\" \/><\/p><\/blockquote>\n<h2><strong>Color Fringing Defined<\/strong><\/h2>\n<blockquote>\n<h3>Types of Fringing<\/h3>\n<ul>\n<li>Color fringing (usually visible on high-contrast edges in the image) can result from several physical phenomena:\n<ol>\n<li>Lateral (transverse) chromatic aberration (red\/green fringes, blue\/yellow fringes),<\/li>\n<li>Axial (longitudinal) chromatic aberration (purple and green fringes),<\/li>\n<li>Flare due to lens-lens and sensor-lens reflections (ghost images), and<\/li>\n<li>Charge leakage in CCD sensors (thin purple fringes).<\/li>\n<\/ol>\n<\/li>\n<li>Adobe&#8217;s existing &#8220;Remove Chromatic Aberration&#8221; checkbox (introduced in Camera Raw 7.0 and Lightroom 4.0), and its predecessors (Profile-based &#8220;Chromatic Aberration&#8221; slider, and manual Chromatic Aberration sliders) handles issue #1 (lateral CA) only.<\/li>\n<li>The previous Defringe popup menu (Off \/ Highlight Edges \/ All Edges) in Camera Raw 7.0 and Lightroom 4.0 handles issue #4 (CCD charge leakage) only.<\/li>\n<li>Up till now, Adobe did not have solutions for problems #2 (axial CA) and #3 (flare).<\/li>\n<\/ul>\n<p>Notes on Axial (Longitudinal) CA<\/p>\n<p>The new Defringe controls are designed to fix axial (longitudinal) CA,\u00a0color aberrations due to ghosting or flare, and color aberrations\u00a0(thin fringes) due to charge leakage, which affects some CCD sensors. \u00a0Here&#8217;s some context on axial\/longitudinal CA:<\/p>\n<ul>\n<li>It can happen anywhere in the image (not just image borders).<\/li>\n<li>It affects nearly all &#8220;fast&#8221; (wide aperture) lenses, typically\u00a0most visible at the wider apertures (e.g., f\/1.4 thru f\/2.8).<\/li>\n<li>Fringes become less visible as you stop down the lens (e.g., more\u00a0visible at f\/2, less visible at f\/8).<\/li>\n<li>Fringes are usually most visible just in front of or just behind\u00a0the plane of focus.<\/li>\n<li>Fringes typically appear purple\/magenta when they&#8217;re in front of\u00a0the plane of focus, and appear green when they&#8217;re behind the plane<\/li>\n<li>of focus.<\/li>\n<li>Even at the plane of focus, high-contrast edges (especially\u00a0backlit) may show purple fringes due to flare.<\/li>\n<\/ul>\n<\/blockquote>\n<h2><strong>How to use the new Defringe Controls<\/strong><\/h2>\n<blockquote>\n<h3 style=\"font-size: 15px;margin-top: 0.83em;margin-right: 0px;margin-bottom: 0.83em;margin-left: 0px;color: #222222;font-family: Verdana, Helvetica, Arial;font-variant: normal;letter-spacing: normal;line-height: 13px;text-align: -webkit-left;text-indent: 0px;background-color: #ffffff\"><a name=\"Description_of_Global_Defringe_C\"><\/a>Slider Overview<\/h3>\n<p>There are 4 sliders:<\/p>\n<ul>\n<li>Two amount sliders (Purple Amount, Green Amount). These are normal\u00a0sliders.<\/li>\n<li>Two hue sliders (Purple Hue, Green Hue). These are &#8220;split&#8221;\u00a0sliders.<\/li>\n<\/ul>\n<h3 style=\"text-align: -webkit-left\">The two &#8220;Purple&#8221; controls are intended to be used to remove purple\u00a0fringing (regardless of the cause).<\/h3>\n<p>The &#8220;Purple Amount&#8221; slider determines the strength of the purple\u00a0fringe removal. The range is 0 to 20, with default 0 (which means\u00a0disabled). Higher values mean stronger correction, but may also\u00a0negatively impact colors of real purple objects in your image. Note\u00a0that fringe removal is limited to the hue range defined by the Purple\u00a0Hue slider (see below).The &#8220;Purple Hue&#8221; slider determines the range of hues removed. This\u00a0control has two knobs, which determine the endpoints of the hue range.<\/p>\n<ul>\n<li>Click-and-drag either knob to adjust one endpoint at a time.<\/li>\n<li>Click-and-drag the central bar (the part of the slider between the\u00a0two knobs) to move both endpoints at the same time.<\/li>\n<li>Double-click a knob to reset its value to the default.<\/li>\n<li>Double-click the central bar to reset both endpoints to the\u00a0default.<\/li>\n<li>The minimum spacing between the endpoints is 10 units. Hence,\u00a0dragging the left knob too close to the right knob will cause the\u00a0right knob to move automatically, to preserve the minimum spacing\u00a0of 10 units.<\/li>\n<\/ul>\n<p>The Green Amount and Green Hue sliders work similarly for green\u00a0fringes. However, the default range for the Green Hue slider is 40 to\u00a060 (narrower range) instead of 30 to 70. This is to help protect\u00a0common green and yellow colors (e.g., foliage) by default.<\/p>\n<p>These controls are best used when viewing an image closely (e.g., 100%\u00a0or higher).<\/p>\n<h3 style=\"font-size: 15px;margin-top: 0.83em;margin-right: 0px;margin-bottom: 0.83em;margin-left: 0px;color: #222222;font-family: Verdana, Helvetica, Arial;font-variant: normal;letter-spacing: normal;line-height: 13px;text-align: -webkit-left;text-indent: 0px;background-color: #ffffff\"><a name=\"Option_Key_Feedback_Visualizatio\"><\/a>Option-Key Feedback (Visualization) for Global Controls<\/h3>\n<p>Alt\/Option-key visualization is available for all 4 controls. I highly\u00a0recommend using these visualizations to help set the slider values\u00a0appropriately:<\/p>\n<p>Option-key + click-and-drag on the Purple Amount slider to visualize\u00a0purple fringe removal. The preview window shows only the affected\u00a0areas of the image (all other areas will be shown as white). This lets\u00a0you concentrate on the affected areas and verify that the purple\u00a0fringe color gets removed.<\/p>\n<p>Option-key + click-and-drag on the Purple Hue slider (either knob, or\u00a0the central bar) to visualize the range of hues to be defringed. The\u00a0preview window &#8220;blacks out&#8221; the affected hue range. Pay attention to\u00a0the borders of the &#8220;blacked out&#8221; area and check if there are any\u00a0residual purple\/magenta colors.<\/p>\n<p>Works similarly for the Green Amount and Green Hue sliders.<\/p>\n<h3 style=\"font-size: 15px;margin-top: 0.83em;margin-right: 0px;margin-bottom: 0.83em;margin-left: 0px;color: #222222;font-family: Verdana, Helvetica, Arial;font-variant: normal;letter-spacing: normal;line-height: 13px;text-align: -webkit-left;text-indent: 0px;background-color: #ffffff\">Description of Eyedropper Tool<\/h3>\n<p>The 4 global Defringe controls above are powerful, but new users may find them tricky to learn. For this reason, there is an &#8220;eyedropper&#8221;tool so that users can click directly on the image to help set the appropriate parameters.<\/p>\n<p>Using the eyedropper for Defringe is similar to using the eyedropper to using the White Balance selection eyedropper: when you&#8217;re in the LensCorrections -&gt; Color tab (so that the Defringe controls are visible), select the eyedropper and click on a fringe in the image. \u00a0It helps to be zoomed in (e.g., 200% or even 400%) to\u00a0facilitate accurate\u00a0color picking.<br \/>\nClicking on a pixel will cause the Defringe system to perform a local analysis of the pixels in the neighborhood, resulting in one of the following 3 outcomes:<\/p>\n<ul>\n<li>It determines that you clicked on a purple fringe, and it\u00a0 automatically adjusts both the Purple Amount and Purple Hue\u00a0 sliders.<\/li>\n<li>It determines that you clicked on a green fringe, and it\u00a0 automatically adjusts both the Green Amount and Green Hue sliders.<\/li>\n<li>It determines that you clicked on an area that was too neutral or outside the supported color range (e.g., all white or gray area or an orange color) and reports an error message.<\/li>\n<\/ul>\n<p>While moving the eyedropper tool over the image, you will see the eyedropper icon change to purple or green and the Purple Hue or Green Hue slider highlighting.\u00a0 This shows approximately what hue you&#8217;re currently targeting, and which of the two fringe colors (purple or green) would be adjusted if you were to click.<\/p>\n<p>Press ESC or Return\/Enter to dismiss the eyedropper sampling window once you have done with the selecting the purple and green fringe colors.<\/p>\n<h3 style=\"font-size: 15px;margin-top: 0.83em;margin-right: 0px;margin-bottom: 0.83em;margin-left: 0px;color: #222222;font-family: Verdana, Helvetica, Arial;font-variant: normal;letter-spacing: normal;line-height: 13px;text-align: -webkit-left;text-indent: 0px;background-color: #ffffff\">Description of Local Defringe Control<\/h3>\n<p>The global Defringe control is sufficient in many cases, but sometimeslocal refinement is required. One reason is the need to &#8220;protect&#8221;certain scene colors (prevent them from being defringed). Another reason is to help suppress some minor residual fringing in aparticular area.\u00a0For these reasons, Defringe is also available as a local adjustment.<br \/>\nDetails:<\/p>\n<ul>\n<li>Available as a brush or gradient (as with all our local adjustment channels).<\/li>\n<li>Only available in PV 2012.<\/li>\n<li>Standard range is -100 to +100, default 0.<\/li>\n<li>Minus direction (towards -100) means &#8220;do not apply defringe to the affected area.&#8221; This is a way for the user to &#8220;protect&#8221; certain image areas from being incorrectly defringed. For\u00a0 \u00a0 example, applying a strong purple fringe removal may indeed effectively remove those fringes, but it may also desaturate or otherwise (undesirably) alter edges of purple objects in your\u00a0 \u00a0 picture. Painting with Defringe -100 over those areas will completely protect them and keep them at their original color.<\/li>\n<li>Positive direction (towards +100) means &#8220;apply additional defringing to the affected area.&#8221; This is a way for the customer to fine-tune and take care of small problem areas.<\/li>\n<li>For images that have only limited color fringe problems in a specific area, it may actually be easier (both faster and safer) to use the local Defringe control.<\/li>\n<li>Note that local +Defringe will remove fringes of all colors (not just purple and green) and hence is independent of the global Purple Hue and Green Hue settings.<\/li>\n<li>The maximum strength of local +Defringe is limited (not nearly as strong as global defringe), so for extreme cases you will need to use the global Defringe instead. (In general, I\u00a0 \u00a0 \u00a0 \u00a0recommend using global Defringe first anyways, then following up local Defringe if needed.)<\/li>\n<\/ul>\n<\/blockquote>\n<h2><span style=\"font-weight: normal\"><a name=\"Suggested_Workflow\"><\/a>Suggested Workflow<\/span><\/h2>\n<p>1.

The letters in front have purple fringes (&#8220;Meghna&#8221;), and the letters in back have green fringes (&#8220;Happy&#8221;), with some alternating green-magenta bands. These are typical symptoms of axial chromatic aberration. With the new defringe filter, the purple and green fringes are largely reduced. Note that this is not a straightforward desaturation (which would turn the letters and cake gray).<\/p><\/blockquote>\n<blockquote><p>Overview of image:\u00a0<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/lrj.mattalbright.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2012-04-25-at-2.49.03-PM.png\" alt=\"Screen Shot 2012 04 25 at 2 49 03 PM\" width=\"600\" height=\"400\" border=\"0\" \/><\/p><\/blockquote>\n<blockquote><p>Closeup, original:\u00a0<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/lrj.mattalbright.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2012-04-25-at-2.49.16-PM.png\" alt=\"Screen Shot 2012 04 25 at 2 49 16 PM\" width=\"600\" height=\"402\" border=\"0\" \/><br \/>\nCloseup, with defringe:\u00a0<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/lrj.mattalbright.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2012-04-25-at-2.49.25-PM.png\" alt=\"Screen Shot 2012 04 25 at 2 49 25 PM\" width=\"600\" height=\"399\" border=\"0\" \/><br \/>\n<strong>Example 3: Champagne<\/strong><br \/>\nSimilar situation.
