With iOS 15 you can natively view the EXIF data of photos, without having to install third-party apps.
With iOS 15, every image in the app Photo has a new “Info” button that shows the image format, the details of the camera used to capture it and the location where it was taken. Before now, there was no way to view this information directly in the Photos app, but you had to install a third-party app or use other devices. This new interface can also be used to add captions and to see the location where a photo was taken, plus there is an option to adjust the metadata EXIF such as the date of acquisition.
Some photos will also have a symbol next to the Info button, which means there is information you can see in mode Search for. For a photo of a flower, for example, the Photo app is able to compare it with other flower images on the web, providing a possible identification of the flower.
There is also a new option that allows you to tap the “Live” button on any photo of this type to automatically turn it into a loop, bounce or long exposure.
