How to edit your photo metadata in iOS 15
When you snap a digital image, you are capturing more than just a pretty picture. Metadata is also recorded and this includes when and where the image was taken, along with its file size and resolution.
You’ll also see which device you used to take the image, as well as the focal length, aperture, shutter and ISO. Unfortunately, you couldn’t edit these without using a third-party app but, with iOS 15, it’s now possible to change the date, time and location.
