I believe you know Adobe PhotoShop. It's a very famous and complete software for photo editing. But do you know Paint.NET? It's also a photo editing software. But it's free. It's open-source. Now, the latest version is Paint.NET 3.31If you're looking for a photo editing open-source program with special effects, layers support and an easy-to-use one, you should use Paint.NET.
I recommend this because you can get it for free. You can use it to complete most of your photo-editing works. It can edit most of image files. Click here to download. It's only 1.5 MB, but it's powerful.
