The hardware feature in the S9's primary 12-megapixel lens mechanically opens the aperture at either f/1.5 or f/2.4 to make those low-light images so they can be as bright as they need to be!
The S9 camera can slow down a video clip to 960 frames per second at 720p resolution for 0.2 seconds to create a 6-second clip you can share with your favorite social networks. Isnt that amazing?
