A spectator signs a card. They're given an undeveloped photograph to hold. The card is lost back in the deck. Before their astonished eyes they watch as the photograph develops into an image of a hand holding their signed card.
Photosynthesis is a powerful way to reveal a word, an image or a signed card.
No camera required. Comes complete with the Photosynthesis gimmick and a 24 minute instructional DVD including several routines.
Photosynthesis is a utility prop you can use to make startling revelations. It looks like an ordinary undeveloped instant photograph but will reveal anything you like in including words, cards, images and even signatures.
