It isn’t going to be just the Nexus 5 users who are going to benefit from Google’s emphasis on photography in their latest flagship device: as it turns out, the camera app, which is part of AOSP, comes with a photo editor which in my opinion is one of the most powerful ones ever.
While it offers a significant number of preset filters for the casual user, there are numerous options for those who want finer control, and also allows them to save their combination of effects as a preset that they can reuse on different images later on. The editor is also non-destructive (i.e., your originals are safe). Do check out the video below to get the complete picture.
