For this exercise I used Photoshop, Big Huge Labs, Filter forge and Lunapic to manipulate a series of images.
This is the basketweave pattern - how different does it look just with a couple of simple filters?
The drip was also very interesting.
The letter motif produced a particularly exciting range of motifs.
This is a really absorbing process - the main challenge has to be how to realise some of the effects you can create in seconds on the pc into something "real"!
