Under the Hood: Building Facebook Camera

The Facebook Camera app for iPhone was developed with a focus on merging photo capture and consumption into a single interface. The team iterated on UI design for displaying multi-photo posts, captions, and tags. A key decision point was whether to start in camera mode or feed mode, influenced by iOS lock screen camera updates. A prototype was developed that places a mini camera roll at the top of the feed, providing easy access to the camera and recent photo thumbnails, serving as a prompt to share and working well with the lock-screen camera.
