*** Apollo operates on Portrait Mode photos (requires iPhone 7 Plus, 8 Plus, X or NEWER). *** Apollo is the FIRST application that enables you to add light sources to your **Portrait Mode** photos, after the photo was taken! Apollo reconstructs a 3D map of your photo which you can augment with new light sources in real time. Take your portrait mode photographs from awesome to unforgettable by selecting the color, intensity, distance of a light and illuminate your photos and selfies to your heart's content. *** WARNING: Taking portrait mode photos requires iPhone 7 Plus, 8 Plus, X or NEWER. *** Apollo is the first app to use the depth data of your portrait mode photos to calculate photorealistic light and shadow. Using a proprietary processing algorithm running on your iPhone's graphics card, Apollo is able to render light sources on a portrait scene or selfie in real time. Apollo allows professional photographers and amateurs alike to try things that are not possible in the physical world. You can shape scene lighting by adding or even removing light. Since lights are computationally rendered in the scene, it is possible to put a light source within the frame: say hello to invisible lamps! The UI is optimised for use with one thumb, allowing you to always view the entire photo. One price, no in-app purchases and no subscriptions. We hope that Apollo is part of the computational photography revolution. We are doing our best but your support is crucial. Send us your feedback, ideas or bug reports on our support email. Show off your lighting chops on our social media outlets. --- Instagram: @apollo_illumination_app and share with tag: #apollo_illumination --- Facebook page: apollo.illumination --- Follow us on twitter: @Apollo_illum or share with tag: #apollo_illumination
