Camera Effect

[KoryB87]

hey everyone! I’ve seen a lot of similar tricks on TV, like James Corden and AGT (Shin Lim) of effects where they take a picture of a spectator holding a blank playing card and later on when they pull up the picture they’re holding the selected card! WHAT IS THIS CALLED?

Rainbow Card is the most recent version of this, I think. There's also a couple apps, the names of which escape me but they're pretty cool, which can essentially edit a card into a photo you're taking.
