Histogram equalization attempts to evenly distribute values across an image’s histogram. Color Only mode can increase global color contrast. An active shadows/highlights control and blend ranges protect blown highlights and shadows. High-radius low-amount (HiRaLoAm) unsharp masking is a technique for increasing local contrast, or “clarity.” The radius is large compared to that used for conventional sharpening, often an appreciable fraction of the overall image dimensions.Īdvantages: the plugin is able to use radii of thousands of pixels for very large images.
(Please note that IrfanView 64 bit uses only 32-bit filters.)įine USM Sharpen/Deblur gives you full control over the unsharp masking and deconvolution processes, including halo elimination, luminosity mode, very high amounts, edge masking, and blend ranges.Īdvantages: dual-mode USM and deconvolution, halo control, and integrated edge masking.
They work for me in Photoshop CS2 and CS5, PhotoLine 21, PaintShop Pro 2018, and IrfanView 4, in Windows 7 and 10. Įach filter is available in three versions: 64-bit for most 64-bit applications, 32-bit for most 32-bit applications (running in either Windows 32 or 64 bit), and an XP version for some 32-bit applications. GNU General Public License if someone wants to make Mac or Linux versions, that’s fine with me.Ĭan I run these filters on a Mac? Or on Linux? Yes.
I have provided the source code and released them under the Retinex and Very High Radius High Pass Contrast include bug fixes.Īnd run in Windows applications.
The Retinex filter now allows for independent adjustment of the luminosity and color components.The “glamour blur” functionality of the Very High Radius Unsharp Mask filter is now its own filter, with more targeted controls and an edge mask.Four-channel separation now includes the option for six-channel adjustments.Fine USM Sharpen/Deblur has an improved edge mask, and improved interaction between the two sharpening methods.General improvements include an improved progress bar, an HTML help file for each filter, and an active Shadows/Highlights control and blend ranges for the contrast-increasing filters.Version 1.2 of each filter, and several new filters, were released in March 2018. They have reduced memory requirements and should run better on larger images, with linear dimensions of 10,000 pixels or more. Version 1.201 of eight of the filters were released in June 2018. They have an improved shadows/highlights mask and some speed improvements. Version 1.202 of four of the filters (Very High Radius Unsharp Mask, Very High Radius High Pass Contrast, Adaptive Histogram EQ, and Adaptive Contrast Curve) were released in June 2019. They use the same method for creating blurred masks as some of the other filters, and are suitable for images with linear dimensions of 10,000 pixels or more. The Very High Radius Contrast Mask and Very High Radius Shadows/Highlights filters were released in June 2019. More information is available on the download pages. Here is an overview of the plugins that I have made for Photoshop and compatible applications such asĮach of them was made with specific goals in mind I have pointed out the advantages of each plugin.
