As many visitors of WyomingJarbo.com will see. I use Photoshop a lot. But you may not be willing to pay the price for Photoshop. So there are some free alternatives that you should check out.
One is GIMP. Originally made for Linux, but has a Windows version as well. It’s pretty advanced, so check it out.
Another is Paint.NET . I think it was named this because people should realize how outdated Microsoft Paint really is. It supports JPG, GIF and PNG. You must have the .NET Framework update installed on your computer.
Both are great for photo retouching. But you should also have a copy of Picasa2 on your computer as well. It does retouching, and organization.
Check those out, and stop using Microsoft Paint.
