When working from a “subject” there is a tacit, physical transmission of verisimilitude as the hand or brush leaves traces that bring what is seen in the world to life on the surface of the painting. When working with another painting as the subject, a similar thing happens. It’s impossible to create a copy of an existing work. What happens is we find how our hand an eye respond to what we see before us. Working on an original painting is an open ended process. Nothing can show us what it’s supposed to look like or whether it is finished. Working from an existing work we can continually compare to see what has been captured and what is still missing as we look between our canvas and the original. I believe these elements are what make this process so rewarding. Once we’ve internalized what the study has shown us it then feeds and stimulates everything we do.
