Enhanced RAW shoots Our iPhones can take great raw shoot but auto settings generally prefers the lowest shutter speed at cost of iso. This is great when you request a JPEG or HEIC shoot, since it's noise reduction algorithm is very effective but isn't very good when you take an unedited RAW. To improve noise ratio, Lumina will recalculate exposure to lower ISO value and keeping an acceptable slow shutter speed. Like other modes, also in RAW, Lumina analyzes hands and scene steadiness to calculate the maximum possible shutter speed value. Bracketing Mode Take a true bracket like on your DSLR camera. Lumina will keep ISO for every shoot! You will get a 3 shoot bracket with a range form -3EV to +3EV. If possible ISO settings will be keeped to give a blend-friendly result. Selfie Mode Lumina can automatically detect when is a selfie scene and will enable Selfie Mode. In Selfie Mode, Lumina will take a couple of shoots and select the best. Lumina's Selfie Mode uses Apple's Vision api, that can valutate shoots based on face expression, open/closed eyes, people smiles and other euristics.
