Photo Pos Pro
Photo Pos Pro isn't as popular as Paint.net and GIMP, but it's another top-quality free photo editor packed with image enhancement tools.
The interface is smarter and more accessible than GIMP's menus and toolbars, with everything organized in a streamlined and consistent way. There's also a 'newbie' option layout similar to Fotor's filter-based approach.
Smart Layout features both layers and layer masks for sophisticated editing, as well as tools for manual leveling and curve adjustments. You can still access the one-click filter via the main menu.
Pros:
- Smart interface
- Beginner and Advanced Modes
Cons:
- Limited output file resolution
