Enhanced RAW shoots
iPhone sensors are able to take stunning RAW shoots but its exposure algorithm often gives priority to higher shutter speed at cost of ISO.
Doing so it increases the chances to take perfectly still shoots but at the same time introduces more noise to the final shoot. Noise itself isn’t a big deal when shooting in JPEG or HEIC since the integrated NoiseReduction algorithm is very efficient in retain details while removing unwanted noise pattern but it becomes crucial when requesting an unedited RAW image.
To improve noise ratio, Lumina will adjust exposure to lower ISO value while keeping an acceptable slow shutter speed.
Thanks to Stability Detection technology Lumina knows what is the minimum shutter speed for every scene.

HDR Mode
Professional grade HDR mode. HDR is a photography technique that involves a fusion of multiple shoot of the same scene to obtain the best possible results.
Lumina can recover up to 2EV stop from clipped highlight and up to 1EV stop from shadows.
To enable this, Lumina, in HDR mode takes up to 3 shoots with variable shutter speeds then, using its powerful AI models, blends pixels wise each shoot to create a stunning image.
The key for an optimal HDR shoot is to determine the right exposure of each shoot in the bracket, in order to retain the maximum recovery room.
Lumina determines the right under/over exposure delta analyzing histogram in realtime.
Lumina uses Metal technology to speed up this process up to 10x.
Lumina's HDR mode is paired with others AI models that can predict in which scenario the best result is archived via an HDR shoot or via an enhanced single-shoot.

NightMode
The unique NightMode algorithm of Lumina enables all iPhones to take stunning shoots even in complete dark environment. Lumina combines the power of AI with powerful Computer Vision technique to archive the longer possible exposure while retaining the right color balance. The final image is the result of hundred of thousands of operations, they are processed using the power of Metal API and are performed in realtime.
Night Mode takes full advantages of Lumina's Stability Detector algorithm, that almost avoids blurry images.
In fact, the maximum shutter speed has two main limits: 1) maximum shutter speed for that iPhone model and 2) the scene stillness. The first can be resolved by some well known Computer Vision technique while the second need special AI model.
