Tanel Posted February 7, 2008 Share Posted February 7, 2008 This plugin (LCE for short) allows to clarify flat or hazy looking photos. It also adds depth or three-dimensional look sometimes. For most of photos you won't need it, but sometimes it's very useful: for distant landscapes or clouds for example. By default the effect is very subtle - to provide enhanced, but still natural looking result. Menu location: Effects > Photo. Download as part of my plugin pack. Updated to version 1.2 (2008-12-24)! Changes: few UI and code optimizations. Updated to version 1.1 (2008-08-31)! - Compatibility fix for paint.net 3.36 Controls: Amount - percentage of contrast to be added Radius - width of contrast detection area Smoothing - reduces the effect gradually at extreme shadows and highlights, to avoid overprocessed look or color clipping. Amount 10-30 should be sufficient for natural result. Radius should be chosen according to image size. There is no rule here but generally: the larger the image, the greater radius you may need. 60 is about optimal for screen size image. 90 or more for large (>3MP) images. 30 for web size images. Smoothing at default setting 5 prevents color clipping in extreme shadows and highlights. Increasing it mutes the effect in shadows and highlights even further. Reducing to zero turns shadows/highlights preserving off. Notes: Similar effect was possible with Sharpen+ plugin, but this one is specially configured for contrast enhancement and is twice faster. Contrast is applied to pixel's brightness only, preserving original hue and saturation. Try also special contrast effects: with several (3-4) passes at reducing radius and growing amount (for example Amount/Radius: 10/60->20/30->30/10). Below are some links to tutorials describing the LCE technique using Photoshop's Unsharp Mask. This plugin does the same, but avoids color shift and clipping problems noted in those pages. <!-- m -->http://www.cambridgeincolour.com/tutori ... cement.htm<!-- m --> <!-- m -->http://www.earthboundlight.com/phototip ... -mask.html<!-- m --> <!-- m -->http://www.luminous-landscape.com/tutor ... ment.shtml<!-- m --> <!-- m -->http://www.lonestardigital.com/photoshop_quicktips.htm<!-- m --> (note: radius 50 in Photoshop is about equal to radius 100 in Paint.NET) Samples: 1st pic - original 2nd pic - LCE, defaults Resized to 40% for web sample. 1st pic - original 2nd pic - Advanced Greyscale plugin: R 100, G 50, B 0 3rd pic - LCE, 4 passes: Amount/Radius 10/60->20/30->30/10->40/5 (Smoothing always 5).

davidtayhs Posted February 7, 2008 Share Posted February 7, 2008 Thanks, Tanel, for another excellent plugin! I've used your Shadow/Highlight plugin to effectively recover details in many photos with horrible exposure settings. Tried using this Local Contrast Enhancement after the Shadow/Highlight plugin and found that the photos looked even better. Thank you!!!

Leif Posted February 7, 2008 Share Posted February 7, 2008 Hmmm. When used on a drawing this plug-in makes some pretty peculiar effects. But peculiar, as in; i got to figure out how to use this to my advantage. :wink: Quote My DA: http://leif-j.deviantart.com/ -------------- Some people seek justice so persistent, that they will do great injustice themselves.

Fisherman's Friend Posted August 27, 2008 Share Posted August 27, 2008 This is important! Since I've updatet to 3.36, LCE doesn't work for me! Before it worked without a problem, now I get everytime something like this: Does anyone else has this problem? I really need LCE! If no-one can be of aid I have no choice and will have too downgrade backwards to 3.35. Quote Link to comment Share on other sites More sharing options...
