In the recently released macOS Mojave, Apple has added another feature to its Continuity suite called Continuity Camera. The feature lets you take a photo or scan a document with your iPhone's camera and have it instantly available on your Mac. Continuity Camera works with several native apps including Pages, TextEdit, Keynote and Notes, and basically bypasses several steps that you would normally take to get a photo from your iPhone into a document on your Mac.
Those looking to re-use an older iPhone X case with a brand new iPhone XS may run into trouble. Cases designed to tightly fit around the rear camera bump are facing a change in size between models. While the difference is slight, the iPhone XS camera bump is larger in length compared to the camera on the previous model.
If you owned an an early generation iPhone (or any camera phone or digital camera) before it was equipped with GPS, chances are you have photos in your camera roll that have no location information. iPhones now geotag your photos automatically (unless you have turned the feature off), which helps with categorizing them and allows them to import into your "Places" album. You can, however, add locations to your "dumb" photos using Apple's Photos app on a Mac. Here's how to do it:
iOS 11 adds a tool that, in theory, ensures your camera is perfectly perpendicular to a horizontal surface you are photographing (so, say an object on a table top or on the ground). The feature is integrated with the grid tool, so it will help you take squared off, symmetrical photos. To use it, go to Settings -> Camera and turn on the grid. Now when you point your camera toward the ground, a pair of crosshairs will appear, one fixed and one floating. Line them up to ensure your photo is level.
Digital photos contain lots of metadata including information about the camera they were taken with, a timestamp and, if the camera is equipped with it, GPS data. This data can be viewed by anybody, so it raises privacy concerns. While there are many apps that allow you to edit this data, you can also simply turn off location services for your iPhone's camera in Settings -> Privacy -> Location Services -> Camera. Check off "Never."
