Every time you take a photo with the new iPhone, you activate billions of edits. Learning the art of photography has always entailed at least some math. Whether it was the relatively simple calculations that were needed to understand the exposure parameters or the almost impenetrable combination of numbers needed to navigate through the parameters in an old-fashioned flash, there were always numbers behind the process. What is a candle? Modern cameras, however, bring even more math than anything else in the past. In fact, Apple's new iPhone XS Max camera makes "billions" of calculations, but you, the shooter, never see them. In fact, it is only thanks to a new functionality (which has nothing to do with the real mechanics of photography) that the camera of the iPhone even mentions a photographic concept of a fundamental time such as the number f, which tells you how much light your lens passes through can leave the aperture. I filmed for a few days with the iP...

Since very few smart rings are actually being sold, it's hard to know exactly what's inside these finger-mounted devices, but we do have some clues. The backbone of every smart ring is Bluetooth technology. Bluetooth is a close-range wireless technology that allows any two Bluetooth-enabled devices to communicate with each other as far away as 328 feet (100 meters) [source: Bluetooth]. You've probably seen hands-free Bluetooth headsets that let you make cell phone calls without actually holding the phone. Like those headsets, smart rings contain a Bluetooth chip, which is really a small radio that can transmit and receive signals from nearby devices. Like many Bluetooth-enabled devices, smart rings need to be paired with a smartphone to work. Once your phone recognizes and pairs with the smart ring, the two devices can talk to each other. Bluetooth makes it possible for smart rings to function as notification devices, and also as remote controls for Bluetooth-enab...
