A very visual effect, performable for all scenarios. The Magician shows a card box and ask the spectator for their phone. The spectator takes a picture of the front of the box and picks a place on the picture to zoom. While the spectator is holding the box in their hands, magic happens! The zoomed picture matches the front of the box that has zoomed in on the spectator's hands.
A great effect that works in the spectator hands where the box can be fully examined! It works as opener and closer of any card magic routine. A card magic effect that doesn't require the spectator choosing a card!
