After upgrading to iOS 15, you might as well try this tip: open the "Photos" app, select an image, and swipe up. Wait for a moment...
Did you see those numbers and terms? This information is presented in iOS 15 in this way, and may be more novel to you.
You may be familiar with metadata or not, but we need to review it quickly from time to time. When you take pictures with your phone, the device saves a lot of other information in addition to saving the image itself. Exchangeable Image File Format (Exif) data is a type of metadata that is particularly relevant to a photo, which may contain the date and time of shooting, location, camera make and model, and even specific camera settings. It's exactly this information you see when you swipe your photos up in iOS 15.
View Exif data on iPhone
Before iOS 15, the easiest way to view Exif data on iPhone was to use several workarounds, because the phone itself wouldn't show too much information. Now, as simple as we described above: Open Photos, select an image, and swipe up. You can also select an image and click the information icon ("i" in the circle) below the image to view the same data.
Edit Exif data on iPhone
When you open the data for a specific photo, you can enter the title at the top. Just click to add the title and start typing. This is very useful if you want to remember the name of something or take any notes.
Below the title, you will see the day of the week, date and time of the photo taken. Click Adjust next to this message to adjust these information. This is very useful if you downloaded or received a file from someone else and want it to have the correct date. Once you enter the Adjustment menu, you will see the original date and time (you cannot change it), as well as the adjusted date and time. Click the calendar to select January 1 1 year (this is not a typo, you can trace the date of the image back to centuries before the invention of the camera) to any date between December 31, 10000. You can also edit the time and time zone here. A tip about time zone: Entering a time zone name may not work well, so please enter the location of the photo instead.

You can't edit the next set of Exif data, but at least we'll tell you what it means. It includes the camera brand and model (for example, Apple iPhone X), the type of lens used (probably a wide-angle camera or telephoto lens), camera settings, image resolution (in megapixels), pixel size, and the file itself size.
Finally, you will see where the photo was taken, or the option to add the location . If you want to add or change the image location, click this option and enter a location in the search box. Select your preferred location from the options that appear. If you want to delete the location, click to adjust , click X to the right of the search box, and select No position that appears.
Other Exif data in iPhone photosIf you receive the image from someone else, it will carry its own metadata. If their phone associates a photo with a location, it will include that location and you can always delete it. If you want to make sure your phone doesn't send location data with the photos, you can edit it before sending it to someone else, or turn it off altogether. To eliminate all location information, open the Settings app, click
Privacy, go to Location Service, and make sure that the camera and the photos are both. Set to Never. Finally, if you save the image from elsewhere on the internet, it may contain basic information such as "Save from Instagram" or "Save from Safari". Screenshots will be displayed as "Screenshots" with limited data for Exif.
Huh, it's finally done. Just a quick swipe to get so much information.The above is the detailed content of A beginner’s guide to image metadata on iOS 15. For more information, please follow other related articles on the PHP Chinese website!

Windows stuck on 'undoing changes made to your computer'
Jul 05, 2025 am 02:51 AM
The computer is stuck in the "Undo Changes made to the computer" interface, which is a common problem after the Windows update fails. It is usually caused by the stuck rollback process and cannot enter the system normally. 1. First of all, you should wait patiently for a long enough time, especially after restarting, it may take more than 30 minutes to complete the rollback, and observe the hard disk light to determine whether it is still running. 2. If there is no progress for a long time, you can force shut down and enter the recovery environment (WinRE) multiple times, and try to start repair or system restore. 3. After entering safe mode, you can uninstall the most recent update records through the control panel. 4. Use the command prompt to execute the bootrec command in the recovery environment to repair the boot file, or run sfc/scannow to check the system file. 5. The last method is to use the "Reset this computer" function
