Reproducing a work of art (or anything for that matter) is always an interesting technical challenge. Perhaps most importantly colours and the geometry of the original work need to be accurately represented. Or as accurately as possible.
The other day a painter of many vibrant colours and of dark passions, portrait painter Emma-Leone Palmer asked me to shoot her latest body of work. What I found very important about reproducing her oil paintings was to preserve the vibrance of her colours without introducing unwanted reflections. Paintings are also three-dimensional objects and keeping (or hinting at) the reality of the canvas and the strokes are essential.
As you can see in the diagram on the right, the setup was very simple: two powerful strobes with softboxes.
