contort

Contort is a feature-packed yet but easy to use photo editor, that even includes a wide variety of filters.

Contort has clear, symbol-based menus that make it very easy-to-use. To edit photos, simply drag and drop them into the program's interface. Not only that, but you can drag multiple photos into Contort, and it can stack them all within the same layer simultaneously, without slowdowns or problems.

Once the images are imported, you can start to edit them with Contort's wide variety of features. The distortion tool can modify any element of the image: just selecting it and then adjust it using the button on the upper part of the menu. There's also loads of filters to choose from, that can make your image look like anything from a painting to a classic 1920s photograph, as well as a fusion tool, that can combine elements from multiple images into one file.

Overall, Contort is a decent photo editor that offers many of the same features as popular programs such as Photoshop or GIMP, although it's much easier to use, even for users with no photo editing experience.
