It's exclusively targeted at astrophotography, but https://www.rc-astro.com/resources/NoiseXTerminator/index.php is an awesome tool for that. He also provides a tool called StarXterminator that extracts separate star and background images so that you can process them separately and then combine them afterwards. I use the PixInsight plugins but he also offers Photoshop plugins. Cost is $60US for one, $100 for both.For astro and wildlife photos I regularly shoot high ISOs.
There are also StarShrink and GradientXterminator plugins for Photoshop by the same author.
