This is a pretty helpful spell whenever you want to remember things. It takes a picture of whatever the wizard looks at when he casts the spell (it only requires a small piece of paper to cast). Then the picture can be transferred to whatever else by simply tapping the wand on what you want to transfer the picture to and saying the spell backwards. I know that some wizards can take multiple pictures but I haven’t figured that out yet.
And it’s this spell that got me in all my trouble. If it wasn’t for that person in the crowd outside the Dragon’s Nest, there wouldn’t have been a wanted poster all over the Wizard Quarter in Boston.
