Nokia Place Tag Beta has just become available to those on Windows Phone 8 this morning.
Sometimes the app will cause your camera to get a green screen, if this happens it is not only in the Place Tag app but in the stock camera too. To fix this a full reboot is required, after that all is okay again.
“Nokia Place Tag takes more than a photo. It reveals info about the places within your photo, such as museums and famous buildings, which you can then share as a postcard to your friends.
Wish you were here?
You can also use Place Tag to get interesting background info about the places tagged in the photo. And if you need directions, that’s also easily available too.”
