Gradientxterminator Photoshop Plug-in !LINK!
GradientXTerminator is a gradient removal plug-in for Photoshop that is fast, easy to use, and really works. It can process 16-bit or 8-bit images, grayscale or RGB color. It easily tackles large-scale gradients from light pollution, but can also handle vignetting and even tricky edge, corner, and circular gradients that are very hard to deal with otherwise. And assuming you already use Photoshop in your work flow, you may now have one less program to transfer your image into.

In Adobe Photoshop, gradient control can be carried out via basic functions such as Curves, but a Photoshop plug-in that can swiftly flatten gradients and restore an even background colour saves a lot of time.
When astrophotographer Russell Croman (aka RC-Astro) introduced his StarXTerminator plug-in for Photoshop in late 2021, I was intrigued. I have been using his other Photoshop plug-ins StarShrink and GradientXTerminator for some time and find them very useful. So I was curious to test the third member of the RC-Astro plug-in family.
What makes StarXTerminator better is that while it runs as a Photoshop filter, it installs a proprietary artificial intelligence (AI) module that can do much more than any existing Photoshop filter can. The AI has been trained on many images to recognize stars vs deep-sky objects. The StarXTerminator panel has a button for downloading a new and improved AI module when one is released by RC-Astro. The version of the AI module is independent of the version of the plug-in itself.
