Did you know that Photoshop has built-in mechanisms that prevent you from editing photos of banknotes? After getting a payday, Reddit user tarballdotgz tried to Photoshop some of his hundred dollar bills, but ran into the above error in Photoshop. Even if you find a way to edit the images in Photoshop, there’s a good chance your printer will give you a similar error if you try to print the image out!

Update: Another interesting fact: apparently one mechanism used to do this is something called the “EURion constellation“, a specific pattern built into banknotes worldwide. (Thx David!)
