I studied art at Bellas Artes and Artes Aplicadas, Universidad de Chile, many, many years ago.

Now , my medium is the computer through Photoshop.
Sometimes, images are created on a paper with brush or ink or pencil, as well as used any of the above mentioned mediums in combination. Then, on the computer, I work manipulating and experimenting with them, in order to create new images.
But sometimes, is the other way. Primarily, images or background are worked on the computer and, then, treated with different mediums: oil pencil, charcoal, oil, etc.
