This free app uses the iPhone’s dual camera system (iPhone 7, 8 and X) to refocus your portrait shots AFTER you shoot them! Get professional portrait shots with amazing bokeh (blurred background) that you can adjust after shooting by changing the aperture setting and more to get just the right effect. Yes, it works great and is VERY COOL!
Honestly, there are very few reasons to shoot with anything other than my iPhone X now. While pro photographers may disagree, the only real advantage to a DSLR or mirrorless camera is the zoom lens. I challenge anyone to take a better portrait shot with any camera, especially one that fits in your pocket! Focos is a free app and is available in the iTunes App Store for the iPhone 7 Plus, iPhone 8 Plus, and iPhone X. Certain features are unlocked with a $6/year subscription.
