I have listed some of the free photo editing softwares, which are totally free and can be downloaded. Although initially it would be tough to get used to new interfaces of these softwares until you get used to. From what i have seen seashore is easy to use and i have been using it a lot lately. Gimp for mac is also good, but i felt difficulty working with it as i am so used to photoshop interface.
