Paint.net
Price: Free with option to pay to support the project through Windows Store.
The link shown below provides a good description of this photo image editor. I suggest reading through it to see if you want to give it a try.

While I have not used the effects available in this program much (so far), the ones that I find most interesting are:
- Tile reflection: I use this to create somewhat of a window effect. A couple of examples are shown below.
- Pencil sketch: This produces a black and white pencil appearance.
- Ink sketch: This produces a color pen-and-ink type effect.
