Hmmmm.....I suspect that all those tricks use the same principal. A principal that is very deceiving in the hands of a pro, unfortunately....
Well i stopped using camera edits for a start as it was a bit too cheaty even for me.
Of the 3 above, the knife appearance i kinda mess that up and give it away right before it "appears" The keyring one too unfortunately was harder than I thought. However the lighter one I did perfectly, so I am chuffed with that as did it on my first take too.
And when you consider I have about as much magical talent as a brick, I think I have been quite good, considering I am basically useless.
A bad ass who will beat you like he's using the fists of god.
