Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.

Snow Leopard Box Set Briefly Appears in Apple Online Store [Updated]
The Mac Box Set bundles Mac OS X with iLife '09 and iWork '09. A Leopard version was launched in late January at a price of $169, and a similar version will be available for Snow Leopard at the same price point. Apple has noted that the box set will be required for users looking to upgrade from OS X 10.4 Tiger to Snow Leopard, as the standalone OS X Snow Leopard, priced at $29, will require an existing installation of OS X 10.5 Leopard.
The brief appearance of the Snow Leopard Mac Box Set provides further evidence that the launch of Apple's new operating system is rapidly approaching. Snow Leopard Build 10A432 was reportedly designated the "Golden Master" version to be sent to manufacturing for the public release, and several sources have also claimed that Apple may be releasing Snow Leopard as early as Friday, August 28th, ahead of Apple's previously-announced September launch window. Over the weekend, purported photos of the Snow Leopard packaging also surfaced, indicating that manufacturing has indeed begun.
