New app uses Portrait Mode data to make lighting games

The dual camera system implemented in the iPhones 7 Plus, 8 Plus and X allows devices to record photos from the Portrait Mode (Portrait Mode), an additional feature that creates a depth of field effect from the use of these cameras.

Although the new iPhones have more scenery options in Portrait Mode (Studio Light, Contour Light, Stage Light and Mono Stage), it is not possible to make specific light and color adjustments. exactly what the application enters Apollo, allowing the user to edit the portraits captured from the iPhone's dual camera system.

The app is not the first or the only one that makes it possible to edit photos captured by Portrait Mode. Other programs, such as RAW Power it's the Spotlights, use the depth map of iPhones to adjust color and focus of images. Apollo stands out for allowing super-realistic editing the effect of light distance, color, intensity, etc., all from the way the app makes use of depth information.

On the application's dissemination page, the company Index told how it was to develop Apollo and the mission of the application.

Apollo is the first application that uses the Depth Map of Portrait Mode to realistically add light sources to a scene. The development of the app started as an experiment in November 2017, when we put our hands on a new iPhone 8 Plus. We want to know what could be achieved by using the data and information from the images taken from Portrait Mode. Our hypothesis was simple: if depth information can be superimposed on a 2D image, it is possible to re-illuminate objects with customized light sources.

Some functions of the application that allow you to expand the original functionalities of the dual camera system of iPhones are: changing the color, intensity, distance from the light point and lighting of the scene. The software makes use of a graphics card processing algorithm, which allows it to illuminate a portrait scene in real time.

In addition, it is possible to add up to 20 light sources to images, making it possible to calibrate each one according to the 3D position, the light distribution and the color. The user can even position a light source behind an object in his photograph to produce shadows and emphasize silhouettes.

The Apollo app is available on the App Store for R $ 6.90 without internal purchases. It is important to note that only iPhones compatible with Portrait Mode are able to use the functions of the program.
