A series of a single shot (of Jordan, filmed by the incredible Ronin) with a variety of visual effects applied to them. The effects are generated via code – that use the following techniques: time displacement, absolute difference & in the last two clips, dynamically generated brush strokes with an omnidirectional displacement map applied. A custom AIR app is used to generate the code and drive Photoshop CS3 Extended.

My first objective was to continue exploring the Time Displacement and Absolute Difference algorithms I worked on a while back in MATLAB, but port them into my AIR app while at the same time taking advantage of the tools available to us via Photoshop. For a very long time, I have also dreamed about isolating only the moving pixels from one frame to the next, vectorizing them and then applying brush strokes to that area – in effect, only painting where there's movement. The last two shots in this series highlight the dynamically generated brush strokes.

Big thanks to the Ronin (theronin.co.uk) for allowing me to use his footage to experiment with.
