If Paint.NET is your editor of choice and you find yourself needing to open .PSD Photoshop files, this plugin will help you introduce .PSD images into your Paint.NET workflow.
The plugin doesn't replicate all of the numerous functions of the .PSD file, just the ones that relate to functionality within Paint.NET. You can work with layers, load masks, and open a variety of colour modes and profiles. Because of the limited integration with the .PSD file, the plugin is best suited for pulling a .PSD file into Paint.Net and converting it to be used in your Paint.NET workflow. Working with it in Paint.NET and then trying to bring it back into Photoshop is a bit dicier as far as compatibility goes and can have unexpected results. PSDPlugin is free and required Paint.NET 3.0+.
