I often get intimidated by image editing programs because they're usually so rich in features that it just becomes overwhelming. PhotoFiltre Studio is a pleasant surprise, however, making basic retouching and editing of images easy and accessible. It allows you to perform simple or advanced editing of an image and apply a vast range of filters. Everything is managed through the toolbar with which you access the standard filters. It also has a "layer manager" which controls all the advanced brushes, nozzles, red eye remover plus other useful tools.
The filters are easy to use and for anyone not very familiar with using them, PhotoFiltre Studio provides an excellent introduction into what they can do for you. Many provide simple functions such as changing the brightness, contrast, dye, saturation, and gamma levels, etc. However, there are also some much more impressive filters such as those that create watercolor, pastel, Indian ink, or mosaic effects.
It also features tools for more adventurous users such as vector filters that allow you to manipulate images into rectangular, ellipse, triangle, rhombus, and rounded rectangle designs. If you're new to image manipulation or editing, or are just lost when it comes to using filters, PhotoFiltre Studio will make you feel much more at ease.
