The filters range from adjustments to your standard parameters (brightness, contrast, tint, saturation, color correction, etc.) to more artistic touches (watercolor, pastel, ink, pointillism, puzzle effect, etc.).
PhotoFiltre also includes vector selection, using two different types: automatic shapes (rectangle, oval, triangle, rhombus, rounded rectangle, etc.) and custom shapes you can create with the lasso or polygon tool.
If you still think your photos look too basic, PhotoFiltre also has advanced effects like contour and transparency which you can apply to your images with preset skins or ones you've created yourself.
