In GTA IV, protagonist Niko carries a Whiz camera phone that is required in a number of missions throughout the game. You can use the camera phone outside of missions to take photos, too, though they cannot be saved.
You’ve upgraded to a smartphone in GTA V, and the Snapmatic app is what you’ll use to take photos for most missions requiring them. Protagonist Franklin does get chance to use an SLR camera in the 'Paparazzo' mission, and the 'Casing of the Jewel Store' mission provides you with a pair of glasses with a built-in camera, but these are mission-specific and can’t be used elsewhere. A fun feature that has been added at this stage in the GTA series is the ability to upload your photos to social media via the Rockstar Social Club. And yes – you can take photos outside of missions, so get snapping!
The EyeFi service is a combination of hardware and software. An EyeFi SD Card plugs into your camera and has built-in Wi-Fi to upload your photos to the company’s cloud service. From there, you can share images in albums or upload them to social media sites like Facebook, or to other photo-sharing sites like Flickr and SmugMug.
However you can also upload your photos and upload or link your video directly from the Athlete Profiles or Competition Pages (Competition Results or Upcoming Competitions).
