+### Rear Camera

+For photos, the camera will flash much like the stock iOS camera. For video, the torch(flash) will enable for the duration of the video capture.
+
+### Front Camera
+
+For models that support [Retina Flash](https://developer.apple.com/library/content/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/Cameras/Cameras.html#//apple_ref/doc/uid/TP40013599-CH107-SW7), the front camera will use the default flash for image capture. If Retina Flash is not supported, a faux Retina Flash is used similar to Snapchat.
+
+For front facing videos, a white, 85% opaque view will be placed over the video feed for the duration of the video capture.
