Did you know, that photos taken by your iPhone’s camera contain some informations like GPS data? It may impact your privacy when sharing a photo. Hopefully, most social networks purge these data, but social networks are not the only way to share your photos. For example, you may want to send photo by e-mail. These data are called metadata. It may include many informations like camera model, exposition settings, if flash was fired, exact time and date of taken photos and many more. So how to check for these metadatas included in your photos?
Solution is called ViewExif by Steven Zhang. Just download this app from App Store. Please note, that you will need iOS 8 or higher, because it works like extension for “Open with…” menu. After installation, we will need to enable ViewExif for share menu. Go to Photos app and tap on Share menu:
Now tap on More and by swipe enable ViewExif:
Optionally, you can move it in Share menu for desired position, mine looks like this:
After choosing a photo, tap on ViewExif icon in extension menu. You will see something like this:
As you can see, there are many metadatas. Not all are displayed in this screenshot, as there are so many datas. Of course, you can scroll to show more. By Share Menu in ViewExif’s upper left corner you can remove all metadata and send your photo to another person without affecting your privacy.
I tried many photo metadata viewers and ViewExif I found as the best one. Sometimes occur a bug – a field “Name” shows invalid name, but name is not changed by ViewExif, it’s only bug in viewing file name. All metadatas are correct (I tested it) and name is unchanged.
Awesome is, that ViewExif does not only work in default Photos app, you can see picture metadata in many 3rd party apps, as it works as extension thanks to iOS 8 APIs.
