Polarr is a great photo editor for amateur photographers with some advanced features. In addition to having a native app for Windows, you can use Polarr on phones, tablets, and Chrome OS. You can install the Polarr Photo Editor from the Chrome Web Store which fully integrates with Google Drive.
One feature of Polarr is the ability to add text to your photo. This is pretty cool in its own right but with the invert setting you can create some awesome photo text.
Photo text allows you to make professionally looking headers for a web site, or even fancy titles for an ebook with Book Creator. Photo text can also be a great way to demonstrate a concept such as Bee.
