Learn more about Smart aperture and how it takes beautiful images.
Applicable for R17 Pro device.

We always hear about aperture on our phone cameras but seem too technical to think or mind about it. To make it simple, the aperture is that hole in your camera where the light passes through. Changing the size of the aperture affects the light exposure of the images that you will take. 
The size of the aperture is called F-Stops. You will see them as these numbers: f1.4, f2, F2.8, f4, f5.6, f8, and so on. The smaller the f-number, the wider the aperture. More light will come in if the aperture is wider. Check more about R17 Pro device.

R17 Pro has the smart ability to automatically switch the apertures to f/2.4 when shooting in daylight and switches to f/1.5  at night to capture brighter images. You don't need to manually change it. When your surroundings start to brighten, it closes quickly to reduce glare, making every shot effortlessly crisp and clear.
