I edit my photos using editing tools online. I tend to stick with one website until I get bored and then move on to something else, so a lot of my photos will be edited sort of similar because of this.
I always edit my photos. I think it's fun. Even if I am not very good at it. It's just something I do when I have nothing to do.
Since I mainly take photos with a phone camera or a webcam, editing makes them look more interesting.
