I have been trying out the live trace tool on the image below. Here are the results:
I liked this effect of limiting the colours. This would be also useful for screen prints, or limiting colours for printing.
Very striking. Hard to keep detail with this function though.
This looks pretty similar to the original image.
The three colour trace was really interesting. I then transformed the colours with the recolour artwork tool. I like this technique, there is a lot of potential.
