For many, the idea of printing and marketing multiples of a work of art is fairly straightforward: Based on interest and demand, artists determine how many copies to produce of a work – known as “the edition” – and then they make those works available to collectors.

As technologies advance, and as artists develop new and interesting ways to present their work, the familiar editioning model is evolving to accommodate individual artist practices. In this Q&A, art dealer Stephen Bulger addresses some of the innovative variations in editioning standards related to photo-based works of art.
