For the best part of my working life I have used computers to make functional but relatively uninteresting business graphics, flowcharts, graphs, diagrams and so on. In recent years though, I have been experimenting using computers for making art. Definitions of what art actually is vary, but I tend to follow the idea that art is something that has been intentionally and purposefully created or designated to be art.
I use a variety of mainstream software programs, but try to make my work more individual by making my own digital brushes, textures and transparent overlays.
What I have also found is that, just as when using traditional materials like watercolours paints, there is still an element of serendipity (good luck) when working digitally. The trick is recognising when something interesting has just happened, then unraveling what you’ve just done!
