In today’s world of painters, certainly tools are an important part of the job. We can also look at tools as technology. Now many artists, especially those that deem themselves as purists, hate the word technology. They think of its use as cheating. Yet many wouldn’t think it was wrong to use a ruler to make a straight line, and whether you like it or not, a ruler is absolutely a simple form of technology. So is a pen, pencil and easer for that matter. They, like most technology, all use science and invention to make a task easier, or more efficient and often more precise.
