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."
While lens filters for the iPhone's Camera app have been around for several iOS generations now, iOS 11 not only changes the available filters, but changes the user interface as well. Apple touts them in its iOS 11 preview:
"New professional-quality filters take the camera on iPhone to another level. Portrait photos are more expressive. Skin tones more natural. There are even filters for applying classic looks to your portraiture photography."
The QR code reader should be on by default if you have iOS 11 installed. Simply focus on a QR code and your iPhone will notify you that you can go to the website on Safari, or whatever other action the QR code offers (join a Wi-Fi, email somebody, etc.). If for some reason it isn't on, head to Settings -> Camera and toggle on "Scan QR Codes."
Adobe has updated Lightroom Mobile to version 2.7.0. The latest release adds a new feature described as "Authentic HDR" to Apple devices, and makes it possible to export original RAW images directly to the iOS camera roll. While the native Camera app includes its own HDR functionality, Adobe touts their raw HDR as a superior shooting mode.
One of the clearest iPhone 7 images yet has leaked over at Nowhereelse.fr. Showing the back panel of the iPhone 7 case, the photo is further confirmation of design tweaks that have been previously discussed. The reconfigured antenna lines, here in white on a gold colored model, wrap around the edges of the device. A larger opening for the camera is also clearly visible.
