How to take pictures in NFS Most Wanted 2012? What keyboard key should i use to get screenshots?

Until the planned "Dreamshot" mode that was supposed to be in the final game arrivies in an upcoming patch, there's no smooth way to do it if you dont have a 3rd party app such as FRAPS. If you don't have FRAPS and don't want to install it, you can press "Print Screen" and then Alt+Tab out to Windows, open any software like Paint or whatever you're using and paste the image.
