For general information, I am aware that not everyone can afford the high priced photo editors. There is an open source editor, called GIMP. It does almost everything everyone normally does with editors, but is free for the download. You would have to learn how to use it, and techniques required will be different than the usual program. But, it gets the job done.
It was intended for Linux, which I use, but it has been ported to Windows as well.
There are considerable HOW-TO's on the Web.
If you can afford the high priced programs, that is fine, too.
