Filterion

Filterion is a compact photo editor application, made for fast and easy edits to boost up your photos.

It was created with ergonomics in mind, so you can use multiple gestures to change different filters and effects at once. For example, if you select brightness and contrast, you can edit both at the same time in a 2 dimensional rectangle. This way, it's easier to set the mood of your photos as you like, without having to move through different options.

The graphic engine is build upon on Brad Larson's GPUImage library, which means it can apply complex filters on your photos in real time.
