2. VSCOcam is by far my favorite photo editing app, because the filters emulate film. Ever since this app came on the scene I rarely use instagram filters. You can also use the app to lighten, add contrast, saturation, etc.
3. TouchRetouch is genius. I just found out about the app a month or so ago and it has changed my life. You can remove anything unwanted from a photo, sort of like you would in photoshop. In this photo I removed a speaker and a fire alarm, which would have taken the focus away from my subject.
